To manage color in Photoshop, you need to go ahead and configure your color settings which are located underneath the ‘edit menu panel’ of Adobe Photoshop. As you click on the color setting option, a dialogue box will open up. Even though it may look a bit daunting at first but as you precisely go through it, there are only a few things that you will need to understand.
The first thing you need to do after opening the dialogue box is to go to the right-hand side of your box and click in the ‘more options’ button to reveal all of the available options with regards to color settings of Photoshop.
Now, if you start from the top the first option you will see is ‘settings’ drop down menu which has several presets from which you can choose. You can also set your own custom configuration according to the relevance of your artwork and design.
Now, underneath this option we have ‘working space’, and this is where you specify a default color profile for each color mode. So we have RGB, CMYK, Grayscale, and Spot.
A working space is usually considered as a color profile that you use when editing and adjusting your images. It’s not device specific but it has a large enough color range that it can actually contain all the colors that are present in your digital image.
Now, there are many options available for RGB working space. And they are:
Monitor RGB: It sets the working space according to current monitor space. In this option, Photoshop turns off its color management properties.
Color Sync RGB: This profile is specified to Apple Color Sync, and is not for windows.
Adobe RGB (1998): This is the best color profiles to see 8-bit images and for converting RGB mode to CMYK mode. This profile provides a larger range RGB of colors.
Apple RGB: This profile is specified for Mac computers.
Color Match RGB: This profile works only with Radius Press View Monitors.
Pro Photo RGB: This working space provides a very large color range. It was originally named ROMM RGB and later it was named Pro Photo RGB. It is very good for viewing 16-bit images.
Wide Gamut RGB: This color profile also provides a very large color range. This profile can display many colors that can’t be displayed by the monitor.
Color Management Policies
Once you’ve chosen your preferred working spaces we can proceed to configure Photoshop’s color management policies which determine how Photoshop handles color profiles when opening and working with images.
In color management policies, you have three modes and these are RGB, CMYK, and Grayscale. In these three drop-down menus, you can actually select if you want to turn them off or whether you want to preserve profiles that are embedded in the digital file or whether you want to convert to working RGB space.
Underneath these particular color modes, we have a couple of checkboxes primarily for ‘profile mismatches’ so when you actually open up your documents it will ask you, whether you want to actually embedded profile or convert to your existing default working space. You also have a checkbox called ‘missing profiles’ which means if you open an image and it doesn’t have an embedded color profile, it will actually ask you if you want to leave it without a profile or actually convert once again to your default working space.
Color Conversion Options
Now, underneath policies, we have ‘Conversion options’ which as the name suggests is how Photoshop actually manages the conversion process between color profiles. My suggestion would be to leave the engine setting to Adobe (ACE). You’ll also need to actually adjust the ‘intent’ and that is a drop-down window below the engine option.
You will have four options from which you can actually choose from and these are perceptual, saturation, relative colorimetric and Absolute Colorimetric. I recommend that you can use ‘perceptual’ or ‘relative colorimetric’ for photographs and utilize the use of ‘Black Point Compensation’ which controls whether to adjust for differences in the black point when actually converting colors between different color spaces. So, leave this thing checked. Underneath this, we have ‘dither’ option, and also keep this option checked as it helps in reducing banding when converting 8-bit images between different color spaces. Next option is ‘compensate for scene referred profiles’ and this profile is used for videos.
The option that largely assists you with calibrating your monitor is ‘desaturate monitor colors’ which is under the advanced controls. So if your photographic or inkjet prints are actually coming out less saturated than that which you are viewing on your monitor, then you can turn on this setting and add a specific percentage value that will desaturate your monitor and you will be able to balance the two in order to match them more closely which will help with your color management. The default value is given 20%. Under this setting there is another option which is ‘RGB color using gamma’ and you should also uncheck this option.
Note: If you still have any doubts and would like to know more information about any specific option within the color setting, all you need is to do is hover your cursor over that particular option that you have doubt about and you will notice that there is a description panel in the bottom of that dialogue box. And this panel will give you a small technical description of that particular option.
And finally, once you are satisfied with your settings you can save them by going up to this ‘Save…’ button at the top and click it. Thus you have saved your custom settings as a new preset and they will appear in the settings drop-down menu as whatever you choose to save them and name them by.
Understanding Assign Profile And Convert to Profile
Photoshop always uses currently selected RGB or CMYK working space that you have set up in your color settings as an assumption for what those numbers are associated with an untagged document.
For example, if you’ve opened an image which is in sRGB, it will be assumed that it is in Pro Photo RGB if the image is untagged. And that’s simply because you may have Pro Photo RGB selected in your RGB working spaces in my color settings.
The convert to profile command does change the numbers in the document and it will also tag the ICC profile that we’ve selected into the document.
So, assign profile commands and convert to profile commands have some similarities. But the important thing to understand here is that the assign profile command never changes the RGB or CMYK numbers. It simply changes the definition of those numbers.
