ABSTRACT:
A section of film forms a gray scale having a series of portions forming steps with progressively changing densities and is supported below an opening in a top wall of an enclosure with an internegative being supported therebelow, the internegative being movable to allow sequential exposure of a series of separate portions thereof, while using different color selected filtrations. The gray scale and the number and relation of the exposure positions are such that the internegative is used to a maximum extent and such that a color balance is readily seen from a visual examination of the developed internegative.
