Abstract
A photographic packaging system includes a monitoring system which permits the operator to compare frames of the film negative with prints which are being cut so as to assure that the proper prints will be packaged with the corresponding film negatives. The monitoring system includes a television camera and display and a view splitter which is positioned between the television camera and the film negatives. The view splitter splits the field of view of the television camera so that the camera views two separate frames.
