To Thorsten (you posted while I was replying to the above post):

color space internally.

Ofcourse it does. That my whole point. But when you enter a color you enter a
gamma 2.2 color and Pov.Ray just thinks "what the hell" and treats it as if it
was it's internal linear format (doing nothing if system_gamma and
assumed_gamma is 2.2).

Likewize it mangles images this way. It converts f.ex. a Mac image to PC gamma
(system_gamma says so), but it does not convert the image to it's own internal
linear (= gamma 1.0) format.

Please, please (on my knees begging) tell me that you understand the
implications of this and why this is the wrong thing to do.
