When I'm doing stills, I don't particularly like postwork that consists of drastically "painting over" a render. I prefer to get as much out of the software I'm working with first and foremost. I will, however, do minor things like DOF, color correction, and some other minor fixes after the fact for stills. However, when it comes to my commercial works (particularly as an animator), extensive postwork can become a must. It's not a matter of "pride" when there's money on the line, and clients wanting the BEST you can give. My commercial animations usually consist of compositing 3D elements into 2D scenes, so "postwork" is absolutely unavoidable there. You need to do things like color correction for film and video, somtimes I do motion blur in post, or DOF in post because it's much easier and faster. You can't really paint over things to a great extent or fix joints, etc. when doing animation. Well, you can, but it would be extremely time consuming and not very cost-effective. ;-)
