A subtractive color printing device for use between a source of white light and a color transparency or negative intended to be exposed to at least a portion of the spectrum of such source. An aperture is disposed in the exposure path between the light source and the negative. A plurality of color filters, each mounted on a separate carrier frame, are positioned for independent adjustment to different positions between one position fully exposing and another position fully spanning the aperture. Each filter carrier is driven to such different positions by a motor. A computer is programmed to power the motors, upon a user input, to drive the filter carriers to preselected positions.
