Photography is a method of looking. It attempts to define a particular characteristic of a subject and place it on record. Sometimes that moment of record becomes a subject unto itself. The image surpasses reality.
Looking is far different from seeing. I can see the land. I can see a building. I can see the stars. To see acknowledges that something is present. But looking requires interpretation. "How does it look to you?" is a serious question. Past experience, knowledge and judgement are called to service. Seeing the same subject at a different time, a different look is possible.
This is the value of photography as a method. Pushed to its limit, the method forces looking. It constantly requires thought, interpretation and re-evaluation. Every moment and every view through the lens can reveal a subject anew.
