Abstract
Illumination apparatus for a three-dimensional enlarging printer in which a moving lamphouse assembly is tilted at angles that vary proportional to the distance of the lamphouse from the center of scan. The tilt angle of the lamphouse is controlled by a motor or the like to direct the maximum illumination available towards the negative and lens associated with the printer and onto the print film to produce a high quality print rapidly.
