Quote - If I want photo quality I use a camera. 

Riiiight, you just happen to have on hand real nude models with swords and an actual temple in your backyard so you can just run out and snap a photo? How do you photograph something that doesn't exist? The whole point of renders which look like photos is that you can create an illusion of reality.

The movie industry uses cameras all the time, but they also use CG when they want to include stuff which can't be photographed (or filmed) because it doesn't exist.
