Poser Gamma Correction performs an anti-GC on image maps and color swatches, then the rendering kicks in, and then a GC is peformed on the result.This sandwich approach makes it very different from other forms of CG, which work on the final render only (as a post-process).

As a result, the Poser GC affects the effects of lighting / shading only while plainly lit areas stay intact. Vue GC works sort of similar, but different in its details.

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