I nice to see that even Vidpro The Master has problems.
Though Thanks for the Desaturated Idea. I Did a global Desaturated effect as a test. And totally forgot to try single colors alone.
On Challenge 5 pic. I noticed you seemed to have set a gray tone to it. Was this for Clarity alone or perhaps for another reason? (I have noticed that B&W picture layers at a 10% opacity will sometimes add clarity.)
I took the same pic. And darken the highlights until I could have a good idea where her areola was. Added peach color Via above Breast tissue, and used "multiply" at 10% opacity. Then I proceded to auto-level. Darken the mid-tones, highten the shadows. Then reduced Noise for the whole picture by 50%.
