I think the starting point in any definition of photography has to be in the reality outside the computer or camera. Yes, the film industry does a lot of purely digital work now, but there's still a great deal of assembling of pieces of reality -- what was done on film in Citizen Kane is now done in a computer. And there is little difference between the original King Kong and the looming Peter Jackson version when it comes to designing the final image. Somehow, whether the model is digital of physical, it has to match with the live footage. As long as that live footage is there, we're talking photography.
