Abstract: An optical imaging system for producing and applying image masks consisting of an original object holder, an image forming optical system, recording means for the image formed, processing means for the recorded image, means for maintaining the recorded image in precise register with the original object. The recorded image is projected back on the original in a modified form by means of adding and controlling optical flare in the imaging system to control image contract and by well known means control image color and sharpness. This modified projected image in register with the original objects acts as a mask for image enhancement. The resulting enhanced image can then be recorded by photographic film or paper and other ray recording devices.
