METHOD AND APPARATUS FOR RECORDING AND USING EXPOSURE DATA IN A PHOTOGRAPHIC SYSTEM

摘要

A method of operating a photographic camera (10) to provide exposure information in association with a latent image picture frame includes the step of automatically providing (28) a nominal exposure for the picture frame. An operator-selected exposure (32) is provided for the picture frame which differs from the nominal exposure by a known under- or over-exposure. The picture frame is exposed (26) in accordance with the operator-selected exposure, and data (30) is recorded in association with the picture frame indicating the difference between the nominal and operator-selected exposures. A method of operating a photographic printing system is provided, responsive to the recorded data, for marking (74) a photographic print to indicate to an observer the under- or over-exposure of the negative. A method of operating a transparency processing system is provided wherein, responsive to the recorded data, the slide mount is marked (54) with the under- or over-exposure.
