Many thanks for the detailed explanations of all the possibilities. I tried the “power windowing” in DaVinci with a friend who likes to work with DaVinci and achieved beautiful natural effects that give the actor more presence. The area around the eye (dark circles etc.) can also be naturally lightened. A cool tool if you want to give the eye area more presence. As always, the strength of the effect is a matter of taste…
Many thanks to you!
