   Do cameras see what we see?        How does light and motion affect what is captured by the camera?

I am interested in the intersection of image processing and computational photography asking questions that concern with how to obtain what we want from a camera -- the scene as an image as we see, the camera motion, the object motion, the changes occurred at different times, and blurring and geometric distortions or the lack of them.
