Quote - Any help or suggestions...

I certainly don't want to stop the direction of this thread which I think will be useful and informative for lots of people, but going back to the OP for a moment, I'm going to try to take a spanner out of the works - but I may end up by putting another one in!

There is no big deal with Gamma Correction.

(OMG, Mutiny among the Acolytes... prepare the gangplank!)

I mean this: Using GC in Poser enables the render engine to produce renders that:-

a) more closely obey the laws of physics in terms of lighting;
b) are correctly adjusted to be viewed directly on a computer screen without any post work.

a) is the result of using input GC (also called anti-GC);
b) is the result of using output GC.

That's the whole GC deal... no nutshell required. There is a choice which rests with each of us according to our own craft or art.
