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