"Images were first made to conjure up the appearances of something that was absent. Gradually it became evident that an image could outlast what it represented; it then showed how something or somebody had once looked-- and thus by implication how the subject had once been seen by other people. Later still the specific vision of the image-maker was also recognized as part of the record. An Image became a record of how X had seen Y." -John Berger, Ways of Seeing
