Abstract
A rotatable disc is provided, for use in a photographic printer, supporting both scanning and large area transmissive filters. The disc is used to selective position a scanning or large area filter between a photographic negative and a single light sensor. The disc thus permits the single light sensor to be used to measure both the scanned and large area transmissive characteristics of the photographic negative.
