Briefly describes RAND research in developing photographic processes for generating pseudocolor transformations using either two or three separations. Techniques for creating the separations by computer in addition to photographically are presented. The computer-generated separations are more difficult to produce, but they make an infinite variety of transformations possible. Digital information containing the gray levels of an image are input to a microfilm platter and the image is created on 35 mm film. The importance of data handling problems is also discussed. 10 pp. Ref.
