Enhance photo colors
Normally the ENHANCE controls will apply to the whole of a selected photo - but if you just want to make changes to a particular color within your photo then use the ENHANCE PHOTO COLORS option. You might want to change the color of the sky or tweak the brightness and contrast of a patch of grass for example. Additionally there is also the option to make a selected color transparent.
Just click on the SELECT COLORS TO ENHANCE button on the Enhance tool InfoBar to switch into Enhance Photo Colors mode. Now you can click on the part of the photo you want to adjust.
Cross positioned over the color to be selected. The color at the click point determines the color that gets selected in the photo - you will see a brief flash of a chequerboard pattern on your photo, indicating how much of your photo has been selected. Also a red color point appears at your click point.
Red color point at click point
You can click-drag on this to move it around, if you didn’t quite hit the color you wanted to select. As you drag, the chequerboard pattern appears again and it updates dynamically as you do so, so you can see what parts of the photo have been selected. Or to review what you have selected, just click and hold over a point without dragging it to reveal the chequerboard pattern again.
If you haven’t selected all the colors you wanted, you can simply click again to add another selection point. So for example if you are trying to select all of the blue sky in your photo, there may be various different shades of blue in the sky and so you may need to click on several different parts of the sky to capture them all so that the chequerboard pattern covers the whole sky. You can do this as many times as you want, to extend the selection.
Chequerboard pattern indicating color selections You may also find that you’ve selected parts of the photo you didn’t want to select. There are two ways to help solve this problem. You can adjust the extent of the color selection by adjusting fade and tolerance values, and/or you can use a region or mask to limit the area of the photo to which the color selection is applied. See sections below.
Note that enhance photo colors mode is turned off automatically when you leave the Photo Tool or switch to another document.
