ABSTRACT:
A photographic printer for making prints from a transparent original film has a light source for illuminating the transparent original film and a printing lens for focusing light passing through the transparent original film onto photographic paper to create a latent image of the transparent original film. An anisotropic diffusing lens is disposed between the transparent original and the light source for diffusing light only in one direction, perpendicular to a lengthwise direction in which the transparent original film extends, to prevent scratches in the film from causing defects in the prints.
