Photography is a medium that is famous for freezing time. The word snapshot suggests that a tiny slice of time is recorded for posterity.

But we do know that time is also a dimension, like length, breadth and width. In fact, physicists have a model called space-time: suggesting that time is part of a continuum with the 3 dimensions that we are familiar with.

A photographic print is flat, and essentially is made of 2 dimensions: length and width. Yet through composition and lens focus we give a print depth, which is a dimension that is perceived but not physically part of the photographic print. Great photographs (and great paintings) give information in all three dimensions. The best images are the ones which let you feel like you can step directly into the frame into a world which is on the other side.
