The opening paragraph says it all.

Quote - Gamma Correction is probably one of the most baffling and misunderstood concepts in existence. You will find more written about it than you can possibly need or want to digest, and each author will make their own unique attempt at explaining the �ins-and-outs-and-what-have-yous� when in reality most of us don�t really care, and don�t even realize that we�re affected by it almost every time we turn on a computer. Unfortunately when it comes to creating stellar 3D graphics, the use of gamma correction becomes very necessary, even though an in depth understanding of it does not. Fortunately Poser Pro contains some straight forward options for using Gamma Correction. This document attempts to explain the necessity as it relates to Poser Pro in a practical manner while giving you a basic understanding of the process by which you can produce excellent Gamma corrected images using Poser Pro. In effect we�ve tried to simply as much as possible and keep it pertinent.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
