my 2 cents:

while Photoshop CG does the GC-job after rendering only, Poser Pro GC performs a pre-render anti-GC as well. The net effect is a full GC on the "play of light" (shadow, highlight, ...) and a reduced or even absent GC on the object coloring themselves. And... GC reduces the brightness contrasts by definition.

So, the spooky effect on the non-GC (compared to any GC's image), as well as the stronger colors on the Poser CG (compared to the Photoshop GC'd one) are within expectations, at least mine.

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