ABSTRACT:
Successive frames of an exposed and developed customer film are monitored during transport of the film in a first direction, and the information which is gathered during monitoring of discrete frames as well as of the entire film is stored in the memory of a microprocessor. The direction of travel of the film is then reversed and successive or selected frames of the film are copied during intervals between successive stepwise advances of the film in the second direction. Copying light which is used for the making of reproductions of images of the film frames is also used for illumination of film frames during monitoring. A mirror is provided to reflect light to the monitoring unit during travel of the film in the first direction, and such mirror is retracted preparatory to copying which starts with the last monitored frame and proceeds toward the first monitored frame of the film. The film is converted into a growing roll during monitoring of its frames.
