So what do you do if you’ve used Levels to properly set the highlights, midtones, and shadows, but the flesh tones in your photo still look too red? You can try this quick trick for getting your flesh tones in line by removing the excess red. This one small adjustment can make a world of difference.
Open a photo that needs red removed from the flesh tones. If the whole image appears too red, skip this step and move on to Step Three. However, if just the flesh-tone areas appear too red, get the Quick Selection tool (A) and click on all the flesh-tone areas in your photo. (Press-and-hold the Alt [Mac: Option] key to remove any areas that were selected that shouldn’t have been, such as the clothes and hair.)
