[dagmx]

I meant using gamma as a conversion function. There's a whole world of color transformations outside of just gamma. Gamma is just one of many transformations, and you can have two color spaces with identical gamma transforms, but different gamuts, white points etc...

I think a lot of people were misunderstanding my comment. I never meant to imply that gamma is the only important consideration in color perception, I was only reacting to the statement that it was optional. Even color spaces that don't use gamma (i.e. are linear) must have a gamma applied before you can view them.
