Background....saving image...

Well, I’ve been looking at the works in progress forum and Finished Works forum, and I’ve noticed that some people have better image quality then the way I post my pics. They have like a grainy type pic when they post it and it makes they’re model stand out more. I’ve been wondering how to do that, does anyone kno whow? If you need an example I’ll post one.


They’re probably using Ambient Occlusion (in the World buttons) or rendering with Yafray.
