Apparatus and method for making and photographing computer graphic colored images by defining each computer graphic colored image as a plurality of constant color pixel groups, assigning one of a preselected number of colors to each constant color pixel group, assigning one of a preselected number of foreground/background numbers to each constant color pixel group so as to designate its location with respect to the other constant color pixel groups, and exposing a photosensitive material to each constant color pixel group displayed in a predetermined ordered sequence and color so as to maintain the predetermined ordered foreground to background relationship between the constant color pixel groups in the exposure of the photosensitive material to the overlapping areas between the constant color pixel groups.

In a system for defining and displaying an image for photographic reproduction in which the image to be photographed is defined and stored within a computer memory as a plurality of constant color pixel groups and in which each constant color pixel group is displayed to expose a selected photosensitive material at a selected uniform light color and intensity for the appropriate exposure time and in which the time during which the selected photosensitive material should be exposed at the selected light color and intensity is determined for each of the constant color pixel groups and in which the determined exposure times are ordered into a progressively decreasing sequence so that the constant color pixel groups can be displayed to expose the photosensitive material in the ordered sequence starting with the first of the constant color pixel groups in the ordered sequence having the longest exposure time and thereafter adding succeeding constant color pixel groups in the ordered sequence so as to finally display all of the constant color pixel groups, the improvement comprising: means for providing a selected ordered foreground to background relationship between the constant color pixel groups such that said selected ordered foreground to background relationship is maintained in the exposure of the photosensitive material to the overlapping areas between the constant color pixel groups wherein said means for providing said selected ordered foreground to background relationship erases those portions of each constant color pixel group which are overlapped by another constant color pixel group yet to be displayed because of its succeeding position in the ordered sequence.
