But photography is not all seeing in the sense that the eyes see. Our vision, a binocular one, is in a continuous state of flux, while the camera captures and fixes forever (unless the damn prints fade !) a single, isolated condition of the moment. Besides, we use lenses of various focal lengths to purposely exaggerate actual seeing, and we often “overcorrect” color for the same reason. In printing we carry on our willful distortion of fact by using contrasty papers which give results quite different from the sense or object as it was in nature.
