ABSTRACT:
This improved photocopying system projects light from the finder of a camera and through the camera lens to illuminate, on a copy support, the exact area that the camera will photograph. The material to be copied is composed accurately in the illuminated field, the copy lights are turned on, and the camera is operated to make a photocopy. Optical fibers are used to supply light to the finder without overheating the camera.
