### Be gamma correct: Long article on practical gamma correction

**Jun 14, 2009** | tutorial | generic 3D, 3ds Max | gamma_correct_v12.pdf

Gamma correction is one of those buzz words that are really easy in terms of theory and math but confusing in how it is applied in practice. As a consequence, it is largely ignored by many graphics practicioners. This illustrated 11 page (!) article is my attempt in clarifying gamma correction in the context of 3D CGI by answering most of the typical questions: *"What is gamma? Why do we have it? When should I perform gamma correction? And what happens if I just ignore it?"*
