The problem with which this comparative investigation is concerned is the application of a photographically derived image to glass. The image used originated from an ordinary thirty-five-millimeter color slide. This slide, through photographic darkroom manipulation, was translated into thirty individually different, black and white films of four-by-five-inch size. Selected films were then enlarged onto eleven-by-fourteen-inch, Kodalith film. These enlarged films were contact exposed to Ulano's Blue Poly-3, a presensitized silkscreen photofilm. This in turn was adhered to twelve double X silk which was tautly stretched in a wooden frame.
