   I know you need to use blend modes for these but I don't know exactly which blend modes correspond to which photoshop effect. It would be super nice if we could get a chart put together in the wiki by someone who knows about these things.

   Not everybody has Photoshop. You are more likely to get help if you use generic terms, even better give us a picture of what you are trying to achieve.

   Digital image processing more specifically convolution, linear and non-linear filtering is what I think zen is trying to do. Although well covered the net over the necessary techniques/algorithms are not simple. There are lots of book on the subject. Believe me when I say you'll learn more trying to do it yourself than by copying something. You'll have to decide whether or not to use shaders or do it with old school GL operations. There are quite a few "Processing" links on the subject. I wont insult your intelligence by listing a bunch of links. Just google DIP and follow the data.
