Quote - That's not true gamma correction. Postwork GC has several common failings.

1) It desaturates color in non-linear ways. While you can also use the postwork saturation increase, it doesn't come out the same.

2) It doesn't come up with the correct values because the incoming data (images and color chips) are not anti-gamma corrected. Poser Pro does both incoming gamma and outgoing gamma compensation, resulting in linear calculations in the middle. There are plenty of cases where you get wildly different outcomes.

3) Dark data is lost, and cannot be recovered in postwork. I can demonstrate if you don't believe it.

4) Subtle gradients are lost and get quantized - the artifact produced is called banding.

Of course, if you're not interested in that last 5% of quality, none of this matters so you don't need the "Pro" version.

Does this apply to the "artistic lens" method you posted a while back? I like the fact that Poser Pro will perform the incomming gamma correction, since one usually doesn't have gamma corrected materials (and it seems like a real pain to work with mixes.) I'm putting off getting Pro 2010 mostly because of the rendering speed issues, but it will probably be the first software I buy when I replace my current machine.
