From Jamie's still I put in with the render layers a vignetting and a grain. What we need to do now is render each character and background separately so we can stick in some dust. Also thinking about putting a dirty lens effect on it and some sort of haze which I'm just about to look into now and perhaps try.
There's a few things wrong with this shot so please don't point the obvious out, its a test. Also I have given these frames to Kieran Duncan to see what he can do with them :).
