hi BB

to the second (better: 4th) post: I do understand the sense of gamma correcting render results, please do stop the theory and please, if you like, do answer my question.

Poser does not apply a net gamma correction to the result (while exponential tonemapping does, about). Instead, it sandwitches the rendering etc between an anti-GC and a (pro) GC calculation. Therefore, as I have found, the result of Poser GC is not determined by texture brightness at all but by lighting and shadowing instead. And due to the sandwiching, the net effect of Poser GC has nothing to do with the GC needed to map pixel values onto output devices of any kind.

To my findings, in a setup with artificial lighting (like softboxes in a studio), raising the gamma from 1 up creates harder shadows, harder hilights and a loss of color contrast in the midtones.

PS: the difference between GC off and GC=1 is, that when off also explicitely set deviating values in the materials are ignored. For textures which are made to look good on an older Mac, this makes some difference.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
