Hey all,
I’m trying to figure out what the viewer indicator for "Value" is really telling me. That thing at the bottom of the viewer. It’s showing me the R, G and B values, as well as H,S,V and L. Lightness gives me the average of RGB, as it should. An RGB value of 0.5 however, returns V=0.74, while a RGB=0.21404 returns me a V=0.5.
Putting down a new Constant node with the V set to 0.5, still gives me a V=0.74 in the viewer.
From what I understand, Value is simply max(r,g,b) which in a gray-scale image would make no difference.
I’m guessing there’s some gamma:ing going on somewhere. What am I missing?
edit: oh, and I’m talking about 16-bit images, if that matters.
