Quote - despite what proponents of it claim, GC is not always better.  youll never get deep, inky shadows with it which are desirable in some types of art and photography. it isnt always about emulating realism -- youll note that many photographers will take their 'realistic' photos into photoshop/lightroom and play with levels/channels until they get something more dramatic.

a perfect example was here in the poser forum when someone was struggling to do a 3D recreation of a photograph (Morey? Amelkovich? cant remember) of a woman posed against a concrete wall. no matter what they did they couldnt get it, until i suggested they turn off GC and bam they got it.

there is no 'universal solution' to everything. as an artist -- and dont lose sight of the fact that this is art, not mathematics or physics -- you should use all tools and generously shared knowledge at your disposal but feel free to break the 'rules' in order to get the results you want (not what people tell you you should want).

Agree! do some test, have fun, use what you think is right for you, don't become crazy trying to get things the way others say shoud be, I've spend hours tying to get a mood in a render with gamma just because I've read so many time I MUST use gamma everytime, just to find what I wanted was right without gamma, and others renders came out great with gamma.
