I view the scene I'm photographing upside down every time I use my view camera. If nothing else, it does call attention to composition.

Regarding the post from RMLARZ: There is a book called "Drawing on the Left Side of the Brain" that can improve your drawing. It teaches techniques that make you see something as it is, rather than how your brain interprets it. One of the tricks in it is to look at something upside down. This forces you to see light, shadow, shapes etc without reference to how you think it should be.
