"But another reason is learning how to do things. If I see wonderfully realistic hair, I want to know HOW the artist did it, so that I can learn how to do better hair. And since I totally suck at 2D, I want to know if that hair was done in Poser, using rendering tricks that I could learn, or in Photoshop - that I couldn't learn." Painted hair, 3D strand-based hair, and model/transmapped hair all seem fairly identifiable to anyone familiar with 3D. Sometimes model hair is smeared to take out the transmap artifacts or hard edges in post, but that's a very simple process, and anyone can "learn" how to do this if they really wanted to. I think having the option to view postworked images or not is a decent one in theory, but in practice it's not so simple. If I composited shadows, as in my previous example, using the P6 shadows-only render option, would I be obligated to post my resulting image with a "postwork" tag, putting it in the same lot as all the "paint over" works? Chances are, you'd miss out on a great many outstanding images that you could 'learn' from by filtering out postwork in this way.
