Sometimes I find it hard to adjust "correct" skin tones (skin tones as I like them) from clip to clip. It depends on the lightning and all that. But do you have a trick you often use when correcting skintones?
I often make a key, correct with saturation and the gamma correctors. Sometimes also the HSL. But if the lightning is a bit "different" or it is used a wide lense, it sometimes is impossible with only those correctors.
