Also, look around for toon shading tutorials. There are quite a few of them, here and elsewhere.
BTW, I was gonna post this in its own thread, but never got around to it, partly because I didn't think I could do justice to the subject.
There's a fairly new app that just came out of beta called Filter Forge. It's a Photoshop plugin that lets you create your own filters. It uses a node-based system that is quite similar to the shader system used by Poser. I downloaded the beta, but never really got to play with it. Now it's out of beta and muy expensivo - $300. However, people who use it to create popular filters can get it for free. Check out the site link, as it's a cool piece of tech anyway you slice it.
I'm not a big photoshop user, but what caught my attention about this program was the "comic book" filter someone had created with it. I'll save 1000 words here and just show you why:

You can see more variations on the page for the filter:

I wanted to see how it would do on Poser renders. Never got around to testing it, though. :sad:
