Photographers have for a long time been gazing with hypnotic absorption at this mechanical-optical marvel, the camera. Let them lift their eyes and consider that which is in front of the camera. There awaits the model - Mona Lisa in the person of Mary Jones. What are they going to do with her? It would be well if photographers could forget for awhile the expensive camera and it's marvelous insides and the impressive array of chemicals in the closet under the stairs, and concentrate solely and definitely on the model. For it is through the model - whether it be a goat or a duchess - that life is made to stir in the dead substance of the picture.
