I think therefore I am. Sounds good. Not so with photographs. We might confuse the real thing with the image. Looking at the real thing isn't the same as looking at the photograph. When we look at an image we sense the reality but we see the frame which is the boundary of that reality. Our thinking is limited by what we see. Reality involves a different level of interaction. Being there is not the same as seeing it on a print. Look at the photo as a small window into your own thoughts. Then, when you think of the image in that way you won't loose sense of your own reality.
