Some say that photographs should not be altered after they come out of the camera, because that is "cheating."

Once we have said that, we can then apply the concept to the lens and not allow any lens but the "natural" focal length. Then one can get into using different ISO settings or films to capture different levels of light.
Pretty soon, we are back to pinhole cameras and glass plates.
