What is "Value" in HSV?
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, gives me a 0.74 in the viewer.
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.
