Imagine capturing an image and investing hours post processing within Photoshop prior to achieving artistic gratification. The next day, happy with your accomplishment you’re ready to share your photography with the world.

Upon reopening the image within Photoshop you’re shocked to discover that the colors don’t look right, washed out or oversaturated and completely unacceptable.

Photoshop Not Saving Colors Correctly

Immediately wondering, why Photoshop is saving colors wrong? I often get asked this question and the solution to this problem is relatively simple, albeit intricate.

Essentially the image hasn’t been correctly color managed, converted to and embedded with the appropriate color profile. As a result, Photoshop does not have the right information in order to accurately display or print your image.

In this article, we’re going to explore what is color management, why it is important and exactly how to control colors within Photoshop, so that your images display and print as intended.

What Is Color Management?

“Color management” refers to the controlled conversion of color values between various devices (e.g. digital cameras, image scanners, monitors, ipads/tablets and photographic printers) through the use of color profiles to achieve accurate and predictable outcomes.

In short, what you see in your camera and on your computer monitor is a close match to that which is displayed in a photographic print under controlled lighting conditions.

Of course, there are a lot of variables and technical aspects of color management that need to be taken into consideration.

But, it’s important not to become overwhelmed and that how you choose to integrate color management into your editing workflow should be proportionate to your skill level and specific requirements as a photographer.

Also, don’t forget that the complexity of colour management increases when moving between color modes i.e. RGB, CMYK and LAB which can make achieving your desired outcome more difficult.

Color Working Space Profiles

The essential color working space profiles that are predominantly used by the photographic community include:

Each of these working space profiles is structurally different in shape, size and tonal depth which determines the range of potential color values that fall within their boundaries.

ICC Color Profiles - sRGB, Adobe RGB & Pro Photo Gamuts

When working with raw image files, it’s best to attempt to maintain your digital camera sensors original color values and their relationships through using an appropriately sized working space profile.

Selecting an appropriate color profile will depend on your subject matter, lighting conditions and diversity of color. But, essentially as a rule of thumb it’s best to use a profile that contains all of your digital camera sensors potential color values to avoid losing valuable data throughout post processing.

However, sometimes it is unrealistic to maintain large colour working space profiles like Prophoto which contain color values that cannot be accurately reproduced, due to the restricted color range of output process whether that be display or physical print mediums.

For the most part sRGB or AdobeRGB 1998 provide the most appropriate color gamuts that are easily reproducible and therefore won’t cause too many headaches with respect to achieving accurate color between devices.

When Can Color Profile Mismatches Occur?

If Photoshop’s settings aren’t configured correctly, it can lead to colour management mismatches where images are not displayed using the appropriate color working space profile, resulting in poor color presentation and inaccurate color rendering.

Common situations when this problem can occur include:

  • Saving or exporting an image as jpeg (or any other file format) using “Save As” or “Save For Web”
  • Converting between different “Image Mode” color spaces (eg. RGB – CMYK)
  • Sending image files from Photoshop to an inkjet printer
  • When the colour balance of your computer monitor or tablet is incorrectly (eg. you’re running a program like f.lux which adjusts the color temperature according to the time of the day)

What Factors Influence & Can Cause Color Mismatches?

With numerous reasons as to why this problem can occur, an inexperienced Photoshop user can be forgiven for not fully understanding or pinpointing the exact cause of their color management troubles.

Generally speaking, complications arise from not using the correct color profile when editing images within Photoshop. Color profile problems can occur from a variety of incorrect workflow decisions and/or color settings within Photoshop.

Examples of why you may be experiencing difficulties include:

  • Not embedding color profile with images upon saving or exporting
  • Not selecting the appropriate color profile upon opening an image (“Embedded Profile Mismatch”)
  • Selecting “Use the embedded profile” which may not be an appropriate workspace or printing profile for your requirements
  • Assigning an inappropriate color profile to a document
  • Converting a document’s color profile to an unsuitable working space
  • Discarding the embedded profile and ignoring color management practices

A momentary lapse in concentration can inevitably lead to decisions and actions that can negatively affect your color management workflow causing catastrophic outcomes.

Why Is It Important To Prevent Color Management Issues From Occurring?

The consequences of not taking the time to address color management issues that you may have can produce undesirable effects that detract from your overall photographic expression and creative direction as an artist.

Images that aren’t viewed with the intended color profile could appear washed out or oversaturated with disappointing contrast, brightness and tonal values.

Images that aren’t correctly color managed and converted from working space profile (e.g. Adobe RGB) to an output profile (e.g. specified inkjet printer), the eventual photographic prints will not accurately represent that which is viewed on your computer monitor or ipad/tablet.

Additional unwanted expenses (eg. refilling ink cartridges, paper stock or printing services etc) can be accrued due to having to reprint photos that haven’t turned out as expected.

As you can see, color management plays a vital role in maintaining consistent workflow practices that generate predictable results without fail.

How To Solve Color Management Problems & Ensure Colors Save Correctly?

With so many potential things that could go wrong with your Photoshop photo editing workflow, how do you prevent them from occurring and achieve accurate color renditions each and every time?

  • First, ensure that you are editing within the appropriate color working space (e.g. sRGB or AdobeRGB) and color mode (e.g. RGB, CMYK or Grayscale).

    – Confirm your digital camera’s default color profile is set to either sRGB, AdobeRGB or ProPhoto to provide relevant metadata and guidance throughout post processing.

    – Set Photoshop’s default color working space and conversion options from within the “Color Settings…” dialog window.

  • When choosing “Save As” to export your images, ensure that you have selected the “Embed Color Profile” checkbox in the dialog window before saving your work.

    Upon opening or printing an image with an embed a color profile, Photoshop (if correctly configured…) will immediately ask if you would like to continue using the embed color profile for color management.

  • If upon reopening image files, Photoshop doesn’t ask you whether you would like to use the embed color profile, then go to “Edit > Color Settings”.

    Within Color Settings, locate “Color Management Policies” ensuring that all checkboxes listed under “Profile Mismatches” and “Missing Profiles” are selected by default.

How to Preview Your Photographic Print Prior To Printing?

When editing images within Photoshop utilizing working space profiles, any adjustments made can present favourable. However, it’s important not to get carried away making extreme color corrections without fully understanding the impact that it will have on your final output, especially if printing is involved.

To avoid unnecessary heartache and to preview accurate color representations of your photography output, I recommend using Photoshop “Soft Proofing”.

What Is Soft Proofing?

Simply put, soft proofing enables you to remain editing in your color working space (e.g. AdobeRGB) whilst viewing your image through another profile, specifically your printer’s output profile. Thus, enabling you to view your color corrections through the eyes of your printer in real time, without intentionally sacrificing color or tonal values during the editing process.

Of course, it goes without saying that you must have accurate color management profiles for your output processes or otherwise soft proofing will be unreliable and imprecise.

The color profiles supplied by inkjet and paper manufacturers offer potentially great outcomes, however your mileage may vary and you should always test by printing color management charts/scales to compare and contrast.

To configure “Soft Proofing” default settings, proceed to Photoshop’s top navigation menu and select “View > Proof Setup”. Here you’ll find settings that will mimic the potential output of your chosen paper type and printer.

Photoshop View / Proof Setup / Custom

  • Presets – Self explanatory, once you have configured your preferred Soft Proof settings click save and set these as your default settings.
  • Device to Simulate – Select the appropriate color output profile for your paper type and printer. Then, select whether or not you want to “Preserve CMYK Numbers” which will simulate how colors reproduce without performing a color space conversion and affecting the original color values.
  • Rendering Intent – When converting images between color profiles, Photoshop utilizes rendering intents to manage how color values are mapped and organised accordingly within color spaces. There are four rendering intents available and each handles the color conversion process differently.

    Watch the video tutorial above, where I explain exactly how rendering intents manage color values and why I recommend utilizing perceptual or relative colorimetric for photography.

  • Black Point Compensation – Maintaining true blacks when converting between ICC color profiles can be challenging due the variability of color gamuts and rendering intent used. I recommend selecting black point compensation to ensure your images preserve true blacks throughout the conversion process.
  • Display Options (On-Screen) – When printing your photography, you’ll quickly discover that the brilliance of whites and density of blacks displayed on LED computer monitors or ipads aren’t necessarily representative of those found in a photographic print.

    Photoshop’s soft proofing attempts to “Simulate Paper Color” (e.g. offwhite) and/or “Simulate Black Ink” on screen to overcome any perceivable differences. Acting as a visual filter, these settings aren’t applied to your image file and therefore don’t affect tonal values.

To toggle on and off “Soft Proofing” you can go to “View > Proof Colors” or use the keyboard shortcuts “Command + Y” for Mac or “Ctrl + Y” for PC.

By toggling on Photoshop’s soft proofing, it’s easier to evaluate image adjustments in real-time to determine whether or not they will have the desired effect and reproduce as expected.

Troubleshooting

But, What If Your Prints Still Appear Unsatisfactory After Making Changes To Your Photoshop Settings?

Whilst color management is an exact science, when working from home with limited resources it can be easy to forget that you may not have all the required equipment (e.g. color spectrophotometer) or software to manage color with great accuracy.

However, improvements to your workflow can be easily achieved by ensuring that you have correctly configured your Photoshop Color Settings.

Here’s a quick troubleshooting checklist to help identify any potential issues that you may be experiencing:

  • If you haven’t correctly configured your photoshop color settings, there’s a possibility you might be using the wrong color profile. View “Document Profile” to ascertain which profile your document is currently assigned.
  • If you have opened an image in the wrong working space you can utilise “Assign Profile” to apply your original color profile and revert back to its previous appearance.
  • Utilize “Convert to Profile” with perceptual or relative colorimetric rendering intent to change between color profiles accordingly.

In Summary

In this article you’ve learnt what is color management, why color profiles are important, potential causes or reasons why color mismatches occur.

We’ve discussed how to fix color management problems through improved color management workflow practices, enacting fail safes and what to do if you still encounter issues without explanation.

Although we’ve only scratched the surface when it comes to the science of color theory, the fundamental principles that you’ve learnt will help you on your journey to producing perfect photographic prints, time and time again.

Camera Raw’s interface makes it extremely easy to edit RAW image files with precision and can circumvent the need for additional (potentially destructive…) adjustments within Adobe’s Photoshop.

But, what if you don’t have a camera that shoots in raw? Can you still take advantage of Camera Raw’s nondestructive editing?

Well, the answer to that question is yes.

Even if your camera only shoots in JPEG or TIFF, you can still open and edit these files in Adobe Camera Raw and take advantage of most of the associated benefits.

What File Format Types Can Camera Raw Open?

It may not be apparent or obvious, but Adobe’s Camera Raw plugin can open and editing numerous image file formats that include:

  • RAW Files (.CRW (Canon), .NEF (Nikon), .ARW (Sony), .RAF (Fuji) & .DNG (Adobe))
  • JPEG (Joint Photographic Experts Group)
  • TIFF (Tagged Image File Format)
  • PSD

Unfortunately, Camera Raw can’t open and does not support PNG (Portable Network Graphic) or GIF (Graphic Interchange Format) image files.

For a list of all supported camera models, please visit the Adobe Camera Raw Support Page. Select your camera brand for specific information on supported file type extensions and required version of software.

How To Open Camera Raw In Adobe Bridge?

If you don’t want to open up Photoshop, try using Adobe Bridge instead. The Camera Raw plug-in is built directly into Adobe Bridge and therefore you don’t need to load Photoshop.

In order to avoid opening your image in Photoshop, don’t double click on it. Instead right click on your image and select open in Camera Raw. This will open Camera Raw, but it will load within Adobe Bridge instead of Photoshop.

How To Open Camera Raw In Adobe Bridge?

You’ll save a lot more computing power by only opening up Camera Raw and Adobe Bridge at one time, as opposed to having Adobe Bridge and Photoshop opened. Because evidently, Photoshop uses a lot more processing power.

With the way that digital SLR files are these days, they’re a lot larger than what most people are used to working with.

So, by having less applications open on your computer allows your computer to have more processing power dedicated specifically to editing your photos.

How To Set Camera Raw Preferences For Opening Images?

If you go up to the top left-hand corner where the tools are located, you’ll notice that there’s an Open Preference dialogue box.

If you click on that, you’ll see that Camera Raw Preferences will appear displaying general settings.

General

The first one allows you to choose where you’d like to store any changes to images on your computer. You can choose whether you’d like to store those image settings in SideCar XMP files, or if whether you’d like to store them directly in Camera Raw’s database.

Adobe Camera Raw Preferences - General

I prefer to use Camera Raw’s database, but it’s entirely up to you. Next, you can choose, whether you’d like to apply sharpening to all images, or just preview images.

Default Image Settings

From here, you’ll notice you’ll have some default image settings. This is where you can set whether you’d like to apply auto-tone adjustments, auto-gray scale mixes directly to images as soon as they’re opened up in Camera Raw.

Now, I prefer to leave these off, especially if I’ve made changes to a Raw file that I’m quite happy with, and then I open it up again. Because if you open it up again with these settings set, Camera Raw will make it’s own mind up on how the image should look and actually change all those settings on you, which can be quite annoying.

Adobe Camera Raw Preferences - Default Image Settings

From here, you’ve got options whether or not you’d like to specify defaults specific to camera serial numbers. So, if you have multiple cameras that you’re shooting with and picked one of those is your preferred camera, you can set the defaults so they’re only applied to that specific serial number.

You also have the option just to apply defaults that set up in Camera Raw to specific ISO settings.

For example, if you mainly shoot in ISO 100, then you can have all the defaults and the sharpening and the lens corrections all set up for ISO 100. But when you open up a file that’s set to ISO 1600, you can choose that those settings aren’t applied to that file. Because for instance, that file may be a lot more noisy, and you don’t want the same sharpening applied to that ISO setting.

Camera Raw Cache

From here, we have Camera Raw cache, and this is where you can decide how much memory you want to allocate to Camera Raw.

Adobe Camera Raw Preferences - Cache

For example, if Camera Raw’s running quite slow and you have some quite large raw files that you’re working on, you can choose to allocate a specific amount of hard drive space to Camera Raw.

The more you allocate, the faster and the better Camera Raw will perform for you when you’re working on larger files.

You’ll also notice that this purge cache, just here as well. Sometimes if the cache gets a bit clogged up, you can choose to purge the cache and you can also choose to select a location on where that cache is actually stored.

DNG File Handling

I work a lot on DNG files, so this is where you can choose where those files are handled.

Adobe Camera Raw Preferences - DNG File Handling

I prefer to ignore SideCar XMP files because, obviously, with DNG files, that information is already included in a single DNG file.

Also, I like to update my embedded JPEG previews, so that they’re actually set to medium size. This is because I prefer to reduce the size of my DNG files. If I have it set to a full size, then obviously the size of the file is going to be quite larger than if it was set to medium size.

Jpeg & Tiff Handling

Now, as I’m sure you’re aware, Camera Raw can open JPEG in two files, so you can choose how those files are handled in Camera Raw preferences.

Adobe Camera Raw Preferences - JPEG & TIFF Handling

Now, we’ve got some automatic settings here, but you can also choose whether you’d actually like to disable JPEG and TIFF support if you’d like.

Contrasting Processes For Opening Image Files

Now, let me walk you through a couple of different ways of opening your JPEG and TIFF files in Camera Raw.

As you can see, I have a folder open here, and it only contains JPEGs. Let’s now go and double click on one of these JPEGs. As you can see, it’s opened up in Adobe Photoshop which is not what we want.

Folder Containing Jpeg Files

Let’s go and close that. That’s generally what happens.

Instead, Open In Photoshop…

What you can do instead of opening it directly from your folder there, if we were to open it in Photoshop you can select open and view the same folder.

You’ll see they’re all JPEGs there.

Photoshop / File / Open

I’m going to open this file here. But, instead of leaving the format set to JPEG, change that and set it to Camera Raw. We’re sort of tricking Photoshop into automatically opening up your JPEG file in Camera Raw as opposed to ordinarily opening it up in Photoshop.

File Open / Default Format / JPEG

We set that to Camera Raw, and then we go click open. As you can see, it’s now opened up in Camera Raw. That’s how you get around opening up JPEGs or TIFFs in Camera Raw using Photoshop.

File Open / Select Format / Camera Raw

Once you start making changes to your JPEG files you’ll notice that it starts to write those corrections to your JPEG’s metadata. So, it’s nondestructive.

It’s not physically changing the file, unless you want it to. In that case you’d need to go and save it as a new file or open it as a copy of your original JPEG in order to physically change the original file information.

Open Jpeg File In Camera Raw Via Photoshop

But, in this particular example any correction that I make to this file, it’s only getting stored in the metadata which is really neat, especially if you ever want to jump back or come back directly into Camera Raw itself and make further corrections to your JPEG or TIFF files.

With that said, I mean you can do the majority of all the different adjustments that are available to you in Camera Raw to your JPEGs. I mean within reason. Because, obviously, your JPEG files aren’t Raw files. So, they don’t contain as much information as a Raw file does.

But, you do have available to you all of the actual panel options and all of the tools. So, you can primarily make the majority of adjustments that are available to you to your JPEG and TIFF files. So, you’re really not limited.

To make simple corrections you can go through and just work your way through the panel making slight corrections here and there. It doesn’t take you that long until you’ve got a result that you’re reasonably happy with.

In Comparison

In comparison to Photoshop you have to set up different layers, use different filters and different adjustments like levels, curves, color balance, selective color, a whole range of things like that in order to try and reproduce similar color corrections that you can do in Camera Raw within a couple of seconds to a couple of minutes.

There’s a big difference in the ease of use using Camera Raw as opposed to trying to recreate the same results in Photoshop. That’s one of the main advantages of wanting to use Camera Raw to edit your JPEG and TIFF files.

How To Open Multiple Jpegs In Camera Raw?

Simply select the images you would like to open and either hold down Command (Mac) or Control (Windows) or shift. Then proceed to right click and select ‘Open in Camera Raw’.

The other main advantage of Camera Raw is the ability to batch correct by opening multiple JPEG files and adjust them all at once.

You can apply and synchronize settings across a range of photographs saving time, instead of trying to make those adjustments in Photoshop.

It’s very similar to using Adobe’s Lightroom, for example.

How To Change Sky Color In Photoshop Using Gradient Layers https://www.shutterbuggs.com/how-to-change-sky-color-in-photoshop/ https://www.shutterbuggs.com/how-to-change-sky-color-in-photoshop/#respond Sun, 18 Aug 2019 02:01:42 +0000 https://www.shutterbuggs.com/?p=1839 A couple of years ago, I had taken to the skies for my first attempt at aerial photography.

A couple of years ago, I had taken to the skies for my first attempt at aerial photography. With my feet now firmly on the ground, I revisited browsing through hundreds of exposures in an effect to isolate worthy images.

It was long before I discovered an image with reasonable composition and positioning of the elements. Unfortunately, I had missed out on capturing the perfect light at dusk because of the flight time restrictions.

Unhappy with the color of the sky in my photograph, I decided to fix it.

How To Change Sky Color In Photoshop Using Gradient Layers

Photoshop makes it incredibly easier to manipulate the color of the sky through the use of adjustment layers. However, to create a realistic sunset that is graduated in colors you’ll need to utilize gradient layers.

Gradient layers can mimic that effect that is created when using graduated filters in front of your camera’s lens.

What I had originally visualised in my mind was going to require a little bit of photoshop editing in order to achieve my desired outcome.

Letʼs get started…

1. ) Open RAW File In Adobe Camera Raw

In this particular example, Iʼve used Adobe Photoshopʼs – Camera Raw to make my initial raw file adjustments, but you could use whatever program you feel comfortable with such as Adobe Lightroom.

Open File In Adobe Camera Raw

My aim here was to accurately reproduce the diffused September afternoon lighting I had experienced on the day. This resulted in a sound foundation from which to work on in Photoshop.

The final step after making all my adjustments in camera raw is to open the adjusted image in Adobe Photoshop.

2. ) Duplicate Background Layer

Select Layer: Layer ➞ Duplicate Layer

Once the image was opened in Photoshop, I dragged and dropped my background layer on top of the “Create a New Layer” icon which in effect duplicated my background layer.

Duplicate Background Layer

3. ) Apply “Local Contrast” Sharpening

Local contrast sharpening attempts to increase the appearance of larger areas of light and dark transitions, very similar to how sharpening with an “unsharp mask” increases the appearance of fine edges.

But, before I can apply this technique… I need to mask off the highlights within the photograph so not to blow them out past level 255 in the histogram.

A. Select Color Range

Select → Color Range → Highlights

I used color range to isolate the highlights and make a selection. Color range is great for all kinds of purposes, but in this particular instance all I need to do is select hightlights from the drop down menu, make sure the checkbox below is set on “selection” and not image and then click OK.

Select Color Range - Highlights

B. Inverse Color Range Selection

Select → Inverse

The next involves inverting the selection from highlight to mid-tone/shadow as these are the areas I want my sharpening to be applied to. To do this we navigate to select in the menu and click on “inverse”.

Inverse Color Range Selection

C. Add Layer Mask

Layer → Layer Mask → Reveal Selection

The final step involves adding a layer mask to our new background layer using the color range selection weʼve created by clicking the “Add Layer Mask” icon.

Add Vector Layer Mask

D. Apply Local Contrast – Part One

Filter → Sharpen → Unsharp Mask

The concept behind local contrast sharpening involves applying the unsharp mask at a very high pixel radius with a small percentage amount. I personally like to start with the amount value at 25%, radius at 100 pixels and the threshold at 0. This really starts to add depth to a photograph.

Apply Local Contrast Unsharp Mask

Now just be careful though to pay attention to the highlight values in the selection using your histogram. Because in some cases 25% as an amount may be to much and you may need to knock it back to between 10 – 20% in order to avoid blowing out the high mid-tone values in the masked selection.

E. Apply Medium Unsharp Mask

Filter → Sharpen → Unsharp Mask

At this stage, I want to reduce the radius of pixels to about 10 and set the amount percentage to somewhere between 25 – 50% and apply the unsharp mask again.

Apply Medium Unsharp Mask

This is a form of cumulative sharpening where we start off large with the local contrast and begin to reduce the pixel radius.

F. Apply Small Unsharp Mask – Optional

Filter → Sharpen → Unsharp Mask

This stage is optional and depends on whether any sharpening has been applied during camera raw processing.

Apply Small Unsharp Mask

I personally print my photographs up to 40 inches wide. Therefore I prefer to sharpen after I have interpolated my photograph to its final print size. This enables me to better control digital artifacts.

Please Note: The percentage amount should be visually adjusted according to the type of photograph you may be working with and personal taste.

4. ) Create Colored Gradient

Layer → New Fill Layer → Gradient

Because I was unable to capture this photograph after dusk when the earthʼs shadow cast creates an amazing array of colors, I needed to improvise.

New Fill Layer - Gradient Fill

With an understanding of the color spectrum it is relatively easy to recreate in photoshop with a little bit of ingenuity.

Gradient Fill Editor

First I created a custom color gradient layer using the color values listed below. I then adjusted them accordingly to reproduce the effect of the earthʼs shadow.

5. ) Reduce Opacity

With such strong color values, I reduced the opacity of the color gradient layer until the color in the sky became visually pleasing.

Layer Mask Thumbnail - Sky Highlights

This method allows you the greatest control to within 1 percent. After some consideration I finally choose 18% as the final opacity value.

6. ) Masking Off the Sky

Select → Color Range → Highlights

The final step in the process of creating this color gradient was to mask off the areas within the image where I didnʼt want this gradient effect to be applied to.

I used color range to isolate the highlights and create a selection from which I could create a layer mask.

I then clicked on the layer mask thumbnail, holding down the alt/option key which in return displays the mask, enabling me to work on it.

Gaussian Blur Filter

Filter → Blur → Gaussian Blur

Now instead of feathering the original color range selection, which would only effect the outer edges of the sky, I decided to soften the layer mask by applying a Gaussian Blur Filter with a radius of about 50 pixels.

Photoshop Levels - Layer Adjustment

Apply Gaussian Blur to layer masks is a simple way to take the edge of selections.

7. ) Add Levels Adjustment Layer

Layer → New Adjustment Layer → Levels

With the addition of the color gradient layer for the sky, I could see that the lower two- thirds of image required a slight density and color balance adjustment in the mid-tones and shadows to closer match the hues of the evening sky.

Photoshop Levels Adjustments

I therefore, created a new adjustment layer for levels and added a layer mask to exclude primarily the highlights and the sky.

8. ) Add Curves Adjustment Layer

Layer → New Adjustment Layer → Curves

After my levels correction, Iʼd noticed that specific tonal areas in the image had lost there vibrance with the addition of a magenta color balance shift.

Using a curves layer, I was able to target these areas using specific points on the curve, without effecting any other areas.

Photoshop Curves Adjustment - Green

This allowed me to add additional units of green back into these areas. Itʼs a minute change, but it makes a huge difference visually.

9. ) Add Another Curves Adjustment Layer

Layer → New Adjustment Layer → Curves

The highlight values located on the open cliff face of Mt Lindsey were sitting slightly to high. On closer inspection those values appeared unnatural to the eye as a result.

Therefore I decide to add a curves layer to target the highlights at the peak of the RGB curve and adjust the color balance by reducing the contrast of the blue curve.

New Adjustment Layer - Curves

Whilst all the original values were within range, lowering them resulted in a natural sand stone finish.

Add Highlights Layer Mask To Curves Layer

However, I still needed to create a layer mask for the new curves layer to prevent the changes from effecting the highlights in the sky.

10. ) Add Selective Color Layer

Layer → New Adjustment Layer → Selective Color

Selective color is an amazing tool for any type of color balance adjustment, large or small. If you find that you need to make substantial color shifts, try changing the radio button in selective color from relative to absolute for more dramatic results.

Photoshop Selective Color Settings

Here I made a couple of tweaks primarily to the red value, dialing in more magenta to remove the green cast and added black to increase the density. This created the hue and subtle glow of an early summer sunset.

11. ) The Preparation of the Moon

Unfortunately, the moon was not in the original photograph and in actual fact would never have been present at this angle, as this photograph is facing south, south-east.

Original Photography Of Moon

But personally, I think the addition of the moon is a nice touch that adds interest to the shot. I had photograph the moon a couple of months early for such an occasion.

In order to prepare the moon to be inserted into the main photograph, I have to first extract it.

A. Duplicate Background Layer

Layer → Duplicate Layer

To begin, I duplicated the background layer by dragging and dropping it onto the “create a new layer” icon.

Photoshop - Duplicate Background Layer

B. Select Moon Using Magic Wand

Magic Wand Tool ( Keyboard Shortcut – W )

I then choose the magic wand tool and clicked on the black night sky to create a marquee selection and isolate the sky from the moon.

C. Feather Selection

Select → Modify → Feather

Because the moon was photographed against the dark night sky, it leaves a dark outline around the edges of the moon, which would stand out clearly on a lighter background.

Photoshop - Feather Selection

To solve this problem without getting to fiddly, I applied a feathering of a 5 pixel radius to the selection, which will in return softened the edges and gradually decrease the effect of the black outline.

D. Remove the Night Sky

Edit → Clear

Next I need to remove the excess night sky from the background, so that all I was left with was the moon.

To do this I navigated to the menu and clicked on “Edit > Clear”, which in return deleted the selected area from the background layer.

Photoshop - Clear Selected Area Of Image

To see exactly what Iʼd cut out, I needed to turn off the original background layer. What you should see next is something similar to the screenshot on the right.

Photoshop - Moon Background Removal

The end result is that I now have a moon ready to be inserted into the finally photograph.

12. ) Copy & Paste Moon

Edit → Copy – Edit → Paste

At this stage we want to copy the selected moon layer and paste it into the main photograph file.

Another alternative way to do this is to have both photograph files open, so that we can drag and drop the moon layer from the first file on top of the second file. Either way, they achieve the same result.

13. ) Free Transform to Adjust Size

Edit → Free Transform

Now depending of the resolution of the two files, you should see a difference in size. In this case the moon was obviously to large. Using the free transform tool I resize the moon layer to something more realistic.

Photoshop - Transform & Reduce Size Of Moon

Quick Tip: To keep the proportions the same when using the free transform tool, just hold down shift and that way you wont distort your image proportions.

14. ) Select Layer Blending Mode

Layer → Layer Style → Blending Options

What are layer blending modes? A simple explanation would be that layer blending modes enable layers to interact with other layers in different ways.

Photoshop Layer Blending Options

Photoshop Layer Blending Mode - Overlay

In this example Iʼm choosing to use the “overlay” blending option, which multiplies or screens the colors, depending on the blend color of the involved layers.

Photoshop Layer Blending Mode - Overlay Example

15. ) Adjust Opacity of Moon Layer

Layer → Layer Style → Blending Options

The moon was still visually quite bright in comparison to the rest of the landscape in the photo. To address this problem, I adjusted the opacity of the moon layer from 100% down to 80%.

Reduce Opacity Of Moon Layer

16. ) Add Blank Layer Mask

Layer → Layer Mask → Reveal All

The moon still looked slightly out of place in the graduated sky. I came to the conclusion that I needed to graduate the density of the moon.

Add Moon Layer Mask

To do this I had to create a blank layer mask to which I could a add a gradient.

Add Blank Layer Mask To Moon

17. ) Using the Gradient Tool to Add a Gradient to the Blank Layer Mask

Gradient Tool ( Keyboard Shortcut – G )

I then proceed to first select the gradient tool from the tool bar and made sure that the gradient I was going to be using was pure white to black, left to right.

Select Gradient Tool

With the correct gradient set, I want to make sure that the gradient starts with white and finishes with black.

Gradient Tool Settings

The color palettes in the tool bar, decide which color comes first, hence white is on top of black as highlighted in the screenshot to the right.

Switch Between Foreground & Background Colors

After establishing this fact, I zoom in on the moon making sure that the moon layer mask was selected.

Apply Gradient To Moon Layer Mask

Because I only wanted the gradient to be applied to the height of the moon, I needed to guide the gradient tool from the top outer edge of the moon to the bottom.

Gradient Tool Example Application

As you can see the gradient has been added to the layer mask and the moon has become graduated.

Conclusion

When I first started out in photography, I found it extremely easy to become overwhelmed with the amount of information I had to learn on everything from the science of photography right through to color theory and management.

How To Change Sky Color In Photoshop Using Gradient Layers

As technology changed, the transition from film to digital seemed relatively quick in retrospect, although I still remember working of digital film scanners that would take an entire day to scan and render a digital file.

I began learning Adobe Photoshop when it was in version 4, with very limited functionality. Although most of the fundamental tools that were there then, still reside in the software today numerous versions later.

Technology has evolved to a point where nothing is impossible, but the fundamental principles of photography still remain the same. Itʼs these fundamental principles that are the keys to your success and will not only help you become a better photographer, but will enable you to see the world in a new light where photographic opportunities become endless.

Challenges Of Aerial Photography

The corrections I made in photoshop to this photograph were dramatic, but deemed necessary because of the difficulties I had encountered to capture this marvel which included:

  1. Vibrations of the aircraft during flight.
  2. Speed & angle of flight (45 degrees)
  3. G forces of the aircraft.
  4. Daylight hour flighting restrictions.

Because of the nature of where this photograph was taken, multiple reshoots would be almost impossible, time consuming and costly, but this is where photoshop can come in very handy.

As a photographer, learning how to print photos in Photoshop and get the most out of your inkjet printer is important.

The key to printing high quality photographs from Photoshop is being able to understand and configure the available printing options and color management settings to your exact printing requirements.

In this article, we’re going to delve in a little bit deeper and examine what are some of the settings that you can take advantage of inside of Photoshop when printing directly to your inkjet printer.

Keyboard Shortcut: Command + P (Mac) or Control + P (Win)

Go to ‘File’ in the main navigational menu, scroll to the bottom and locate ‘Print’, similar to any other software application that you have utilize.

If you click on ‘Print’ it’ll bring up the print settings. Within the ‘Print’ dialog box there are several important options to configure prior to printing photos directly from Photoshop to your home printer.

Customizing Your Print Settings & Presets

When you’re customizing your print settings, depending on your computers operating system, whether it’s a PC (Windows) or a Mac, you might notice slight differences with respect to available menu options.

Customising Photoshop Print Setting & Presets

You shouldn’t notice any differences with this particular window, however if you click on ‘Print Settings’ there may be small noticeable differences with what you’re currently viewing in this tutorial.

I’m currently working on a Mac.

I have a variety of different options available to me that aren’t necessarily available to you if you’re working on a PC.

So, that’s just something to keep in mind…

However, Photoshop’s print dialog box which we’re currently viewing should be identical to that of a PC.

How To Set A Default Printer

The first thing you’ll notice when you look inside this window is you have your printer option. This is fairly self-explanatory and requires that you choose the type of printer that you want to print from.

Select Type Of Inkjet Printer

Underneath the printer selection dropdown you’ll find all the common options that other software applications use for printing. There is the number of print copies, layout (eg. horizontal or vertical page organization) and print settings which we’ll quickly take a look at now.

  • Printer – Available printers idle on your network.
  • Presets – Customize setting predetermined and saved as a preset.
  • Paper Size – Available paper formats (width x height) printer is capable of working with.
  • Media & Quality – Type of media (eg. paper surface) & print quality setting.
  • Layout – Pages per sheet, border, reverse page orientation and flip horizontally.
  • Paper Handling – Collate pages, pages to print, ordering & scaling.
  • Cover Page – Type (eg. standard, unclassified, confidential, classified, secret, top secret) and order (eg. before or after document).

Essentially ‘Print Settings’ can be customized according to your printer and how you want to set it up.

How To Change Bit Depth When Printing

Underneath print settings is ‘Send 16-bit Data’ which when checked enables Photoshop to send 16-bit data from your photos to the printer for higher quality prints.

Photoshop Print - Send 16-Bit Data

What Is 16-Bit Data Or Bit Depth?

Digital cameras capture light in 12, 14 and 16 bits of information, which may sound all technical…

But, it’s just a fancy way of saying how many levels of information can be captured by your digital camera sensor and stored within each raw file.


An example of this would be a standard 12-bit digital camera and when you times 2-bits by the power of 12, you end up with a camera that is capable of capturing 4,096 levels of information that can be manipulated.

Unlike a standard 8-bit JPEG converted in-camera, which only contains 256 levels of information (0-255).

Dynamic Range Of Digital Camera Sensors

‘Send 16-bit Data’ is quite useful for sending all the information of your image file directly to the printer to produce a higher quality print, without having to convert it down to 8-bit.

In the past, photographic printers (eg. Durst Epsilon’s or Lambda’s) utilized by large photographic labs to print their clients photographs would require 8-bit files in order to print them.

They wouldn’t print from 16-bit files and you’d have to flatten Photoshop files and convert them to printer color profiles to make sure they were ready for printing.

But printing directly from Photoshop you don’t have any of those limitations.

You can print directly to your printer using 16-bit data if you want and achieve a higher quality prints.

Obviously larger file sizes are going to take slightly longer to print because you’re sending more data to the printer as opposed to that of an 8-bit file. In some cases, that’s going to be twice the file size.

How To Position An Image Prior To Printing

Underneath the ‘Send 16-Bit Data’ checkbox is ‘Position’.

Position as the word implies is fairly self-explanatory and allows you to position your printed image precisely within the canvas area of your paper.

Adding a border or deciding whether your printed image should be center or off-center for the purpose of mounting or framing is easy.

Photoshop - Print Position

How To Scale Up Or Down An Image For Printing

Underneath ‘Position’ is ‘Scaled Print Size’ option which enables you to ‘Scale To Fit Media’ or when unchecked to resize your image.

By entering a custom width and height or specifying a scale percentage you can determine precisely how large or small your images will be printed.

Scale Print Size

The link icon indicates that the scale, width and height relationships are locked and preserved.

Therefore, when one value changes it will directly influence the remaining and prevent accidental distortion of the image during resizing.

The majority of time I would select ‘Scale To Fit Media’ unless I required an exact border for mounting and/or rebate for framing.

What Is The Bounding Box?

The bounding box is a rectangle border that is highlighted around the edges of the image. It allows you to move, transform, rotate and scale the image using the mouse cursor.

Colour Management Options

Before I explain each of the color management options…

What Is Color Management & Why Is It Important?

Color management is the controlled conversion of color values and their relationships between various devices such as digital cameras, film scanners, monitors, photographic printers and papers through the use of color profiles.

The prmary goal is to achieve colors that match across each device which in return gives you the photographer consistent results.

The color management options within Photoshop’s print settings present as document or proof.

  • Document – Shows the name of the document profile. When no profile is embedded in the document, this shows the profile as specified in the Color Settings dialog box. If “Photoshop Manages Colors” is selected, make sure to set the profile for your printer in the Printer Profile pull-down menu.
  • Proof – Prints the document by emulating how it will output on another device, such as a printing press. If color handling is set to “Photoshop Manages Colors”, use the Printer Profile menu to specify the profile of the device you are printing to. The proof profile shows the name of the profile used to convert colors to the device you are trying to emulate.

Color Handling

Photoshop provides two options for the handling and management of color values through the printing process:

  • Printer Manages Color
  • Photoshop Manages Colors

I prefer to enable ‘Photoshop Manages Colors’ which I find gives me the greatest control.

Printer Profiles

Choosing whether you want to utilize the documents existing color profile or specifying a color profile that you want to use for soft proofing is easy.

Color Management - Printer Profile

In the dropdown menu, select an appropriate color output profile that you would like Photoshop to convert your image to prior to printing.

Or, if you selected the color handling option ‘Printer Manages Color’ the color output profile you would like the printer to use.

Ink & Paper Profiles

In this case, I’m going to utilize ‘Photoshop Manage Colors’ and specify an output inkjet and paper profile that have been profiled by the printer manufacture Epson.

Under printer profile, you’ll notice that I have quite a few different printing profile options and at the very bottom all of my Epson R1800 paper profiles are visible.

ICC Output Inkjet Paper Profiles

For each inkjet paper surface, I have about two output profiles that I can select according to the particular paper type that I’ve decided to print my photograph on.

Type Of Paper Surface

Each set of printer inks is defined by a characteristic color gamut and it’s ability to be reproduced is dictated by the qualities of the inherent paper surface on which you print.

Therefore, if I were to select my premium glossy paper profile you would notice that it’s potential color gamut is greater than that of premium matt paper and is noticeable on the image preview.

With ‘Photoshop Manages Colors’ checked, prior to printing Photoshop will convert from Adobe RGB to the selected output profile which in my case would be premium glossy photo, an accurate representation of the achievable print quality using Epson premium glossy paper stock.

Conversion Rendering Intent

Below printer profile is the ‘Rendering Intent’ options, which I’ve discussed in a previous video tutorial.

What are Rendering Intents?

Photoshop’s Definition: A computer monitor has more colors and saturation than photo paper. A digital image can have colors that a printer can’t reproduce. Colors that can’t be reproduced are called out-of-gamut colors. The gamut is the color space that a device can reproduce. Rendering intents decide what to do with the out-of-gamut colors.

Four different Rendering Intent Options available and they are:

  • Perceptual – Delivers colors that are natural for human eyes. Takes the out-of-gamut colors and moves them to the closest in-gamut colors. Shifts the inside-gamut colors so the relationship between all the in- and out-of-gamut colors remains the same.
  • Saturation – Preserves saturation over color. Pulls saturated colors out to the edge of the gamut, increases color ‘strength’.
  • Relative Colorimetric – It moves out-of-gamut colors to the closest in-gamut color, keeping in-gamut colors unchanged. Little altering of the colors in the image.
  • Absolute Colorimetric – Good for proofing. If necessary, adds a ‘tint’ of paper color for simulation.

Earlier, I’ve mentioned that utilizing either perceptual or relative colorimetric as the rendering intents would achieve the most desirable high quality results.

Then, I’m going to make sure that I check on black point compensation, because I want to really make sure the black points of the image stay consistent.

What is black point compensation?

Photoshop’s Definition: Black point compensation adjusts for differences in black points when converting colors. If checked, the full range of the source space is mapped to that of the destination space.

This setting is useful if your document and your printer have about the same size gamut, but one has a darker black than the other.

Match Print Colors

If you would like the image preview to accurately match the print colors ensure you have selected the appropriate color management options (including the output profile) and then check the ‘Match Print Colors’ checkbox.

When you turn on and off this option you’ll notice the image preview change. The amount the image preview changes will be determined by the image and the print settings configuration.

Gamma Warnings Preview

Below image preview and match print colors option is ‘Gamma Warnings’.

What are Gamma Warnings?

Gamma warnings as represented by gray in the image preview, identify color values that are outside of the selected printer profile and will not be accurately reproduced in print.

If you wish to overcome these limitations you will need to pay close attention to the conversion process and rendering intents used.

For example, you may want to convert your image into a smaller color working space like sRGB prior to printing.

Photoshop Print - Gamma Warnings

Don’t forget to check out my video tutorial explaining what is Soft Proofing? and how can you use it to your advantage in Photoshop to create optimal color prints.

Paper White

Next, we have the ‘Show Paper White’ setting.

Often when printing you’ll choose a photo paper that has an off-white (not a pure white) surface. Off-white has a warmth and yellow tone that can be easily identified in the highlights or whites of the paper prior to and after printing.

By turning this option on Photoshop will simulate the white point of the paper in the image preview to give you an idea of how your image will reproduce in print.

I’m going to leave the ‘Show Paper White’ option unchecked and turned off.

With respect to color managing of your photographs, Photoshop’s Color Management panel within the Print dialog window offers a high level of control.

Conclusion

After the completion of configuring all of the print settings the image is ready to be sent directly to the inkjet printer for printing.

In Photoshop there are numerous ways of converting color images to black and white, but which method offers the most control and will deliver the best results?

This is a question I’ve asked myself many times and consequently have spent countless hours experimenting with post processing techniques in Photoshop unable to make up my mind…

Here’s what I learnt, no editing technique is perfect. The approach you decide upon will depend on your style of photography and what you would like to achieve as an artistic outcome?

How To Create Black and White Photos In Photoshop

Black & White Conversion Techniques

Within this article, we’re going to explore five different approaches you could use for transforming color photos into dramatic black and white images.

Some techniques are simple, but others require explanation before you can truly appreciate their potential and why you would want to use them as part of your digital photo editing workflow.

1. ) Convert Raw Files To B&W Using Camera Raw

It’s not secret that when working with digital images you’ll achieve your best results by starting with the original, unedited raw file. Whilst these days most photographers edit their raw files within Adobe Lightroom there are those of us that only have available Photoshop.

Luckily, Photoshop comes with a plugin called Adobe Camera Raw (ACR) which offers similar functionality and features to Adobe Lightroom and has been built upon the same powerful raw processing technology.

If you’re in a hurry you might choose to simply desaturate your images by reducing the saturation slider found within the “Basic Panel” of Camera Raw. But, I wouldn’t recommend this method when you could use “HSL / Grayscale Panel” which offers far greater control.

By checking the “Convert To Grayscale” option you will be able to adjust the tonal range of any color by modifying the corresponding sliders value.

The only caveat is making sure that you don’t over work and emphasize the limitations of your digital camera’s sensor.

Bayer sensors for example don’t capture 100% Red, Green and Blue. Instead often only capturing 25% Red, 50% Green and 25% Blue which can make extreme edits difficult to execute without introducing chromatic aberrations and destroying the quality of your image.

2. ) Convert Color Images To B&W Without Camera Raw

So, now that we’ve looked at the raw processing options, how do you convert color images to black and white without using Adobe Camera Raw (ACR)?

I’m glad you asked, there are two options to consider… The first and perhaps simplest involves opening “Image / Adjustments / Black & White”, which I’m not going to recommend because I’m obsessed about quality.

I’ve always advocate for using “New Adjustment Layers” where applicable to preserve the most amount image information during the editing process, even though they increase file sizes.

Layer / New Adjustment Layer / Black & White

So, with that said I’m recommending opening “Layer / New Adjustment Layer / Black & White” which will added to your layers panel in Photoshop. If you don’t see your layers or properties tab you can go to “Window / Layers” or “Window / Properties” in the navigation to enable them.

In the properties tab you’ll find controls similar to the “HSL / Grayscale panel” within Adobe Camera Raw where each slider targets a particular colors tonal range.

In additional to custom controls you’ll also find set of preset filters that mimic the effects you would get from camera filters whilst shooting traditional black and white film.

There is also a click and drag modify icon which will allow you to edit your images by clicking on them, I personally don’t use this feature but that’s not to say you want find it useful.

If you wish to replicate those old fashioned sepia tone photographs from the 19th and early 20th century, tick the tint checkbox, then select the hue and saturation you would like to recreate for your images.

It’s that simple… The black and white adjustment layer in Photoshop can be quite useful for transforming those neglected color jpegs into dramatic shades of gray.

3. ) How To Desaturate Color Images In Photoshop

It’s worth quickly mentioning that Photoshop has an adjustment called Desaturate which does exactly that… It removes all color information from an image, leaving behind only its monochromatic tonal relationships.

So, What Is Monochrome?

Monochrome means only containing or using one color… So, whilst your image may appear to be black and white it still remains in RGB mode vulnerable to color casts which may or may not be intentional.

Desaturate is located under “Image / Adjustments / Desaturate” in the main navigational menu and therefore can only be applied directly to image layers.

How To Desaturate Color Images

Desaturate is quick and doesn’t offer any creative controls. But, if you would like more control over desaturating your images don’t forget to take advantage of the Hue / Saturation adjustment. Simply reducing an images saturation levels and altering its hue can create seductive, monochromatic images.

4. ) Convert Color Images To Grayscale

As you may or may not know image files can be created, converted, edited and saved into different color modes which poses distinct color spectrums designed for specific purposes and outputs.

Color modes you might be familiar with include RGB and CMYK, however you might not of heard of Bitmap, Grayscale, Duotone, Indexed Color, LAB Color and Multichannel. But the color mode we’re interested in exploring is Grayscale.

So, What Is Grayscale?

Grayscale mode converts all colors of your image into shades of gray. For an 8-bit image there can be up to 256 shades of gray ranging from 0 (black) to 255 (white).

Grayscale values can be also measured as percentages which can be very helpful when working with Ansel Adams zone system and/or inkjet printing where the percentage values correspond to the amount of black ink output onto the surface of the paper.

The process of converting an image to Grayscale is relatively straightforward and only involves changing from RGB Color to Grayscale via the navigation menu (Image / Mode / Grayscale) within Photoshop.

Image / Mode / Grayscale

The biggest disadvantage to using Grayscale mode is that you will be required to “Discard Color Information” and therefore that information will never be available to you again, unless of course you return to the raw file.

Discard Color Information

If the thought of never being able to access your original color values throughout the editing process scares you, then you’ll most likely want to avoid converting your images to Grayscale in Photoshop.

5. ) Convert Color Images To LAB

The last method I’d like to discuss involves converting your image to LAB mode. But, what exactly is LAB and why would you choose to use it over the other methods I’ve already discussed?

The CIE LAB color model is based on the human perception of color and it’s numeric values describe all the colors we are capable of perceiving with the human eye.

CIELAB Color Space (Top View)

Image By Holger Everding

Considered to be device-independent, color management systems use LAB as a reference point for predictably transforming color from one color space (such as RGB or CMYK) to another.

The word “LAB” is an abbreviation for its three different dimensions, L axis controls lightness (0-100), A axis controls red (+128) to green (-128) and B axis controls blue (+128) to yellow (-128).

Image / Mode / Lab Color

But because we’re merely concerned with converting images to black and white, I’ll only be discussing how to work with the L axis or Lightness channel which contains all of your images detail, minus its color information.

LAB: Delete Selected Channels

If you go to the channels panel and delete the A and B channel, all that will remain visible is a black and white image ready for post processing.

So, Why Convert To LAB Color Instead Of Grayscale?

Well, Grayscale converts the color values into shades of gray (including all colors), whereas the Lightness channel of LAB only displays the luminance values and therefore delineates tonal relationships with precision and clarity.

But, I’ve found it’s biggest benefit to be the elimination of any potential imperfections that occur from incomplete information captured by digital cameras with bayer sensors (as discussed earlier in this article).

Unfortunately, LAB files aren’t that user friendly when it comes to sharing or printing your photographs. Therefore, you will be required to convert your images back to Grayscale mode, before you’ll be able to save your images in a compatible file format ready for output.

In Conclusion…

We’ve now walked through five different ways to convert color photos into black and white in Photoshop.

Each technique that we’ve discussed have positives and negatives, but hopefully my commentary has helped you decide which technique would best suit your existing digital workflow.

If you have any further questions, please don’t hesitate to leave them in the comments of this blog post and I’ll do my best to answer your questions as promptly as possible.

In this article, I’m going to show you how to create a spectacular panorama using a tripod, multiple exposures and photoshop.

The image I’m going to be working with today was photographed in a small town called Akaroa (75 kilometers east of Christchurch) on the South Island of New Zealand.

Settled by the French in 1840, Akaroa is a charming and perfectly suited to capture the imagination of any aspiring photographer. Directly across the road from my accommodation is the sheltered harbour in all of its splendour and glory.

DSLR Camera and Equipment

Whilst on holidays, I had my Canon 5D, Canon EF 24-105mm f/4 L lens, Manfrotto tripod and Lowepro backpack.

To create my panorama, I started by capturing eight individual exposures (portrait format) that generously overlapped each other. Because I didn’t have any panoramic equipment with me, I wasn’t able to rotate the camera around the nodal point of the lens.

Therefore, I decided to shoot using a longer focal length (82mm) to reduce potential stitching problems that occur at wide angles when not rotating the lens around its nodal point.

Multiple Exposures Panorama

I had visited Akaroa in the middle of June which meant the afternoon sun was quite low in the sky due to the approaching winter solstice. I only had a short period of time to capture all nine exposures and avoid any potential change in light quality or shadows length.

Not to mention, I had to avoid motion blur and freeze the sailboats that were floating in the harbour by shooting at an appropriate shutter speed.

The majority of images were shot at F/11, 1/60 sec at ISO 200.

Once captured, I proceed to open all images within Adobe Photoshop’s Camera Raw plugin which uses the same raw conversion engine as Lightroom.

It’s entirely up to you as to whether or not you use Camera Raw Plugin or Lightroom to edit your photos, as they’re similar in many respects.

Adobe Photoshop Camera Raw Plugin

When post-processing I like to perform the majority (if not all…) of my editing within the Camera Raw Plugin to take full advantage of the information that is contained within the 12-bit raw image.

Before I can seamlessly stitch together all of the photos within Photoshop, first I need to edit each image and make sure that the densities all match.

Even though they were all shot using the same exposure there are still slight variants of around a third of a stop due to the wide angle of coverage and fading afternoon light.

So, how do I ensure each frame has the correct density? I used the “Eyedropper Tool” to sample values found in the blue sky of each image and then used those statistical values as a guide for making density adjustments.

Camera Raw Adjustments

I made several adjustments within the camera raw plugin and have listed them for you below:

  • Exposure Slider – I made slight density corrections based on the digital camera’s original exposure and the RGB values obtained from the clear blue sky of my control image.
  • Recovery Slider – The highlights found on lighthouse and sailboats were pure white and initially blown out. Therefore, I decided to increase the recovery slider to 100 which may come across as extreme, but was required to pull the highlights back into an acceptable range.
  • Hue, Saturation & Luminance – I wasn’t overly happy with the aquas within the images and therefore decided to increase their saturation levels using the HSL panel.
  • Lens Profile Corrections – To reduce imperfections created by the 24-105mm lens and improve the overall quality of the stitching process, I felt it was important to enable lens profile corrections.
  • Sharpen Panel – It was essential to apply a small amount of sharpening (40 units) to strengthen and guarantee definition within the final image.
  • Noise Reduction – I wasn’t expecting to have any issues with noise when considering all images were photographed at ISO 200. However, I wasn’t entirely happy with the amount of color noise I found within the shadows and therefore I added 25 units to the color slider within the noise reduction panel.
  • Custom Crop – Within Camera Raw (Version 6.5) there are limitations when it comes to sizing an image. At the time, I was only able to size my images according to a handful of preset resolutions found within workflow options. My intentions were to size all images to the final print height of 24 inches, but unfortunately the available sizes were just too small. To overcome this problem I used custom crop, not for the purpose of cropping but instead for resizing my images to 16 x 24 inches.

How To Stitch Photos Together Into A Panorama

Photoshop has a feature called “Photomerge” which is what we are going to be using today to stitch my photos together.

Photomerge was introduced in Photoshop CS, so if you have an older version of Photoshop I’m sorry but you’ll need to upgrade in order to take advantage of this feature.

File / Automate / Photomerge

To open Photomerge you’ll need to go to Photoshop’s top navigational and click on “File / Automate / Photomerge”.

Within Photomerge there are two sections of concern “Layout” and “Source”.

Source as the name suggests is where you will select the image files that you would like merged together into one photograph. You can either add files that you already have open within Photoshop or select files that are located on your computer’s hard drive.

Once your file names appear in the dialog window… It’s time to customise our settings. There are three checkboxes below that you will either need to check or uncheck.

Photomerge Dialog Box

The first is “Blend Images Together” which finds the optimal borders between the images and creates seams based on those borders, and color matches the images.

With Blend Images Together turned off, a simple rectangular blend is performed. This may be preferable if you intend to retouch the blending masks by hand.

The second is “Vignette Removal” which removes and performs exposure compensation in images that have darkened edges caused by lens flaws or improper lens shading.

The third is “Geometric Distortion Correction” which compensates for barrel, pincushion, or fisheye distortion within images.

Photomerge Layout Options

Now beside “Source” is the “Layout” option which is how Photoshop will interpret your images. So, depending on how you photographed your panorama these settings can be very useful.

For example, if you used a wide angle lens instead of a telephoto lens your layout option would be different.

There are six layout options: Auto, Perspective, Cylindrical, Spherical, Collage and Reposition. I’ve chosen “Reposition” for my panorama, primarily because it aligns and matches overlapping content, but does not transform (stretch or skew) any of the source layers.

After clicking “OK” photomerge will begin the process of blending all my images together and below you’ll find my results.

Photomerge Output

It’s almost impossible to identify where photomerge has stitched the images together, but if you wish to examine where each image has been joined, simply open the “Layers Panel”.

As you can see there are areas of the panorama that remain empty because that information didn’t exist within the images that I imported into photomerge and therefore I have two options.

The easiest option would be simply to crop the image, but personally I want to retain as much detail as possible, so I’ve decided to reproduce those areas of the image that are missing from the panorama.

I’m quite lucky because the areas that require work aren’t overly complex and therefore should be that difficult to correct.

How To Reproduce Missing Areas Of The Panorama?

In the olden days, I would have had to use the “Clone Stamp” tool for the majority of this work, but Photoshop has become so clever that this is almost not necessary any more.

1. ) Flatten image layers.

2. ) Select white areas using Magic Wand Tool.

3. ) Press “delete” on keyboard.

4. ) Fill dialog box configuration:

Photoshop Fill Content-Aware

NOTE: If you’re working with Photoshop CC, Content-Aware Fill (for transparent areas) is now included within Photomerge and therefore you can skip this step entirely.

Refining Content-Aware Using The Clone-Stamp Tool

Final step in the process of creating my panorama is to correct any mistakes or inconsistencies that have been made by Content-Aware Fill.

Refining Using The Clone Stamp Tool

First, I need to visually identify which areas require improvement. Then using the Clone-Stamp Tool, I select details within the image that would make an appropriate replacement.

I hope you’ve found this insight into how to create panoramas using multiple exposures helpful and inspiring.

Today you are going to learn how to take relatively ordinary photos and turn them into something spectacular using Photoshop, all within the next 7 minutes.

Now for today’s challenge, I’m going to be using Adobe’s Camera Raw plugin which you’ll find inside Photoshop and we’re going to be working on a raw image file.

If don’t have any raw files, don’t worry because you can still use Adobe’s Camera Raw to edit your jpegs or tiffs by simply right clicking on a chosen image inside of Adobe Bridge and selecting “Open in Camera Raw…”

There are so many features and tools in Camera Raw that it can sometimes be hard to know exactly what to use, especially if you’re not familiar with the interface.

So instead of giving you my long winded, raw workflow formula, which could take up to half an hour, I’ve decided to pick out the best bits and show you a couple of tools that I used to transform this image into something worthy of attention.

We’re going to focus on three specific features in this video, the “graduated filter tool, the lens correction panel and vibrance and saturation sliders”. So let’s go ahead and get started…

Graduated Filters

Now because this image has little color, the first adjustment I’m going to make is to add a couple of colored graduated filters, one for the sky and one for the foreground to not only draw focus to the center of the image, but also to impart color that’s currently lacking from this image.

Add Graduated Filters

So you’ll find the graduated filter adjustment located in the tools menu or as a shortcut you can press “G” on your keyboard to select it. Once selected you’ll notice you have an entirely new panel and set of adjustments on the right of your workspace.

I’m going to proceed and add a graduated filter starting at the top of the image and dragging it right down to the bottom of the image. Now this will be primarily for the sky.

I’m going to adjust the “brightness” slider to -150 and then set the a “color” hue of 298 with a saturation of 50 percentage.

So Next, I’m going to do the reverse and add a graduated filter starting at the bottom and working my way to the top of the image with the intention of darkening the foreground.

Graduated Filter Settings In Camera Raw

So let’s go ahead and adjust the brightness to say about -75 and then add a high contrast value of 100 to emphasize the trees as a silhouette.

Lens Corrections

The second key adjustment I’m apply is a “Lens Correction”, this is not only for correcting imperfections in my lens but also for emphasising lens vignetting to draw more focus the center of the image and the sunrise.

Lens Corrections is the 6th panel icon in from the left and within lens corrections there are two tabs profile and manual. In the profile tab I’m going to enable “Lens Profile Corrections” making sure that my camera model, and lens profile are selected.

Lens Corrections Manual Settings

Then I’m going to quickly jump over to the manual tab and where if you scroll to the bottom you’ll find lens vignetting. By adjusting the amount slider to -100 and the midpoint slider to 25 I’m drawing even more attention to the highlights of the sunrise.

Vibrance & Saturation

Now the third and final key adjustment is to fine tune the color and saturation settings of the image. So first, in the Basic panel, I’m going to dial in about +50 units of saturation to give this image a little bit of life. I’m also going to enhance the lower saturated colors by adjusting the vibrance slider (+25 units).

Now if the color relationships in your image don’t quite look right, you can refine them by going to the “HSL or Hue, Saturation and Luminance” panel.

In this example I’m going to reduce the orange and yellow hue sliders to about -25 to produce a richer sunrise without effecting the cooler hues.

Although I wasn’t able to include my entire raw workflow in this video, I think you would agree that the results achieved from three small changes are impressive to say the least.

But having said that it’s important to remember, that changes made in Camera Raw are non-destructive and aren’t permanent, which means you can return and re-edit your images at anytime… So aim to make as many corrections as possible inside of Camera Raw, prior to opening your images in Photoshop.

If you approach raw conversions with this in mind, you’ll extract and preserve an image of the highest quality.

How To Stitch Photos Together In Photoshop With Photomerge https://www.shutterbuggs.com/how-to-stitch-photos-together-in-photoshop/ https://www.shutterbuggs.com/how-to-stitch-photos-together-in-photoshop/#respond Thu, 23 Feb 2012 03:39:35 +0000 http://shutterbuggs.com/?p=1 When looking through the lens, it’s often impossible to do justice to the splendor of mother nature, which as a result, leaves me with so many unanswered questions...

One question in particular that comes to mind from time to time is... What aspect ratio will do justice when photographing this magnificent landscape?

I’ll be the first to admit that when using my digital SLR camera, I can become a little narrow sighted and stuck looking at the world in a 3:2 aspect ratio.

However, when I come across a scene that cries out to be photographed as a panoramic, I like to think that I’m up to the challenge. So, what’s the easiest way to take multiple images and blend them together into a panorama that you can be proud of?

Photoshop makes it incredibly easy to stitch multiple images together to create a panorama from scratch and the best part is Adobe Photoshop CS5 does an amazing job that I honestly can’t fault, which can’t be said for older versions of the software.

In fact it does such a great job that you’ll almost never need to position your lens directly over its nodal point and that’s pretty impressive. The process of capturing and creating a panorama is fairly straight forward as your about to find out:

1. ) Capture Series Of Overlapping Images

Start by capturing multiple images of the same scene using a tripod and making sure that they all overlap evenly and were shot using the same exposure settings.


If you wish to use a Motion Control Head or a Pan Tilt Bracket they will provide you with more precision and options for creating not only panoramas but time-lapse videos.

2. ) Open Bridge & Select Sequence Of Images

Open Adobe Bridge and begin browsing to identify which images would be ideal for superimposing to create your panorama.

Opem Multiple Images Within Adobe Bridge

Keeping in mind that the alignment, movement and exposure of each frame can influence how realistic and seamless the end result.

After labelling and rating your files, select them by holding down the Ctrl (Windows) or Command (Mac) key and clicking on each photo. Then import your images into Photoshop by right-clicking on the selection and choosing open with Camera Raw.

3. ) Edit Images Within Camera Raw Or Lightroom

Open and edit all images identically within Adobe’s Camera Raw. Save all images with the same resolution, color profile working space and file format to ensure consistency.

Adobe Camera Raw Editing

Finally, open all of your saved images within Photoshop.

4. ) Open Photomerge In Photoshop

In Photoshop go to the main navigational menu and select… File / Automate / Photomerge…

File / Automate / Photomerge

Once the photomerge dialog window appears you’ll be asked to select and open all the images that go together to make up your panorama.

5. ) Select Layout Option

In the layout settings, select the type of panorama you’re creating. In most cases, you can get away with using the “auto” option, unless of course you know exactly what type of lens distortions are within your photographs.

Photomerge Layout Options

Finally, make sure you have “Blend Images Together” checked and then choose whether or not you would like “Vignette Removal” and/or “Geometric Distortion Correction” applied. Then click “OK”.

6. ) Check For Imperfections

Double check the quality of the merge and look for any imperfections that may have occurred in the stitching process that require your attention to fix. In most cases you will need to view your image at 50-100 percent in order to visually find any problem areas.


Identify Imperfections

If you focus your attention predominantly around where the images have been stitched together you can’t really go wrong. By turning off individual layers you’ll be able to see where the layer masks connect.

7. ) Crop Image

One of the common problems you may face with your panorama is that your image maybe missing sections either top, bottom or on either side.

Panorama After Photomerge Stitching

If this happens you have two options. Either crop your image tightly and work with what you’ve got or utilize Photoshop’s content-aware fill to fill in these areas. Content-aware fill isn’t perfect, but it does give you a great starting point from which you can work from.)

I think you’d agree that the results speak for themselves… I hope you found this tutorial to be helpful and informative. If you have any further questions that I haven’t answered, please don’t hesitate to ask them in the comments below.
