I remember a dust up here at RMP years ago over a render of Elijah Woods (?) as a Hobbit that won a contest.

 

I wonder what post-work could be used to make a standard celebrity photo look like a Poser render? JPG repair and faux-HDR with some judiscious smudging? Anyone care to take it on? Be a cool experiment... esp. if no merging with an actual render was used.
