It is important to perceive photography as a selection and interpretation of the world in two respects. First, from a point of view of the photographer who selects and interprets a scene or incident in the process of encoding an image. Second, from the perspective of a viewer who interprets (reads) the photograph in the process of decoding. This orientation views the photographic communication as an active process of interpretation, by both the creator and the viewer.
This would also appear to be the view of John Berger.
Every image embodies a way of seeing. Even a photograph. For photographs are not, as is often assumed, a mechanical record. Every time we look at a photograph, we are aware, however slightly, of the photographer selecting that sight from the infinity of other possible sights.
