Could anybody make (if not already made) a plugin which gives an image a dirty, worn down effect to it. If it already exists then I might be searching for the wrong thing, but I'm not entirely sure how to word it. I know about the film plugin but that just adds grain, I want it to look dirtier.
Below is a picture that kind of shows what I'm looking for. See how it looks kind of....dirty. How do I do that?
