You do put things so eloquently, HBorre - much more important detail and far better justification for GCing your materials (or using software-GC).

BB said in another thread that gamma-correction was a pro feature, poorly understood by the masses and so therefore not included in non-Pro versions of Poser. Initially, I disputed the reasoning behind this view. The difference in image quality was significant enough for me to be sold on the concept, and since then I don't render a scene unless all materials have been at least considered for GCing.
Why only considered? Because there are more refined approaches to correcting colours. Corrected-sRGB, for instance.

Implementation does require Matmatic and basically reverse-engineering your shaders in order to insert the corrected-sRGB node set, but the difference between GC and corrected-sRGB is quite remarkable, especially in those lower-light situations.

However, in all fairness to neophyte Poser users, a simpler scheme on the software level needs to be devised to prevent this cranking up of nuclear-powered lights because of a problem with how Poser processes colours. This should NOT be a Pro feature. There should be some default setting that allows Poser users to create reasonable-looking renders without resorting to changing materials for their entire scene.
