This is a bit theoretical but I hope someone can chime in…
I never really understood how gray point worked, so I decided to create a range of fills, apply gray points, and plot the results in an Excel sheet.
Well, I’m now even more confused… 🙂
For one, Levels gray point and Curves gray point do different things. (I confirmed this by Apply Image/Difference). In general, Curves seem to add more contrast (and that’s all without touching black and white points, just the gray!)
Anyway, can anybody throw some light on how Levels and Curves calculate the gray point?
