Correcting skin color with Adobe Photoshop is one of the most difficult
tasks professional photographers face every day. If you are a wedding,
portrait, or fashion photographer, you know exactly what I mean. The problem
is that the range of acceptable skin color is very, very limited, and it
varies slightly for different races. Additionally, subtle skin color is
difficult to render on a computer monitor, so making accurate adjustments is
tricky.
