Abstract
Abstract A photographic modifier and method for photographically modifying graphics and the like. A first transparent support which carries an image is overlaid on one side by a second transparent support which carries a photosensitive material. A light housing containing a light is movable across the first and second supports on the other side of the first support for exposing the image onto the photosensitive material. One of the first or second supports is movable simultaneously with the light housing to create a modification of the image on the photosensitive material as the light exposes the image thereon.
