Photography renders the moment for most photographers. We grab a slice of time and place, cropped just so, to include elements we feel are significant. Four dimensional consciousness is rendered to a two dimensional plane. I would have said three dimensional space, but in reality we are capturing a moment, a moment in time. The camera is a great tool for achieving this. One can depict more time within a picture, and its OK to do so. Forget the highly focused images of Ansel Adams and Elliot Porter for a moment. We really don't see still images, the camera does, but we don't. The camera can be used, I'd argue it should be used, to smear those parts of experience that move quickly and fix those that don't. Imagine the story a photo of a couple embracing in Grand Central Station would have if all those walking by are smeared with a two second exposure. It would tell how a hug trancends the moment.
