Looks like it was shot with a crappy lens at a super high ISO and underexposed, cropped in on hard, and then brought back up with levels. The falloff is from smog, not a photoshop technique. Maybe he added noise to it in PS, but I don't know why you would want to add noise - noise is something that every other photographer in the world who shoots digital works to ensure is not apparent.
this is probably what the photo looked like before it was poorly edited:
