Kind of how you push film, i shot this at HI1 (ISO 6400), underexposed by 1 stop, then pushed the exposure up 1 stop in post. this gives, effectively, an iso 12,800 shot. yes, technically its not, but its almost similar. cleaned up in noise ninja. now, in my opinion, this would be presentable in a size suitable for web viewing quite the step up from my D80
