I posted this originally in "comp.graphics.apps.photoshop" but it
might be interesting to see what people here think...
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?
