Good point, Ole, and I like the way you stated:

"The whole point is to see what's outside your own head, instead of the inside like most people do."

But I don't agree with it completely. There is no way to disassociate yourself from your own, personal viewpoint. The whole point for me is to document my personal relations and interactions with what is actually outside of me and the manner in which I affect it. There are also many wonderful images which are the product of documenting the inside, Sally Mann's "What Remains Behind" and David Levinthal's work with toy figures and the 20"x24" polaroid camera.
