Cameras are powerful tools. They don't just create images, they create perceptions... or even perhaps realities. Reality for us is how we see it, right? If our eyes and brains had evolved in such a way that down looked like up and vice versa (not such a far-fetched theory, really) then we would invariably think of the reality of down and up in such reversed roles.
Generally speaking, we use cameras to reflect our reality...or more specifically or perception of reality (not that they are really all that different in a fashion). But cameras can be used to introduce new perceptions, can't they? Look at the popularity of extreme wide angle lenses? Why do photographers like them so much? Because they show us a perception of a familiar world in a way we cannot normally see it in. It's exciting. I sometimes like taking it a step further. After all, there is a difference between stretching your perceptions of reality through wide angle lenses and completely re-arranging them. When you start to the see the world as re-arrangible building blocks, you start to think of the reality you so take for granted a bit differently too. See, that is what I mean by powerful tools. Cameras not only have the ability to show us the world in a different fashion, they have the ability to make us think about a different world, or even on occasion, believe in it. Crazy stuff.
Or maybe I have just had too much juice to drink.
