ABSTRACT:
An exposure control apparatus for use in photographic printers assigns the originals which are received for printing to groups or sets, for example, according to filmstrip membership, and bases the printing exposure for each such original, at least in part, on characteristics determined for a corresponding set taken as a whole. In a presently preferred apparatus, the exposures for individual frames from a filmstrip are controlled in accordance with the average optical density for the overall filmstrip in selectively weighted combination with individual frame, optical density characteristics.
