ABSTRACT:
A method of operating a photographic camera to provide exposure information in association with a latent image picture frame includes the step of automatically providing a nominal exposure for the picture frame. An operator-selected exposure is provided for the picture frame which differs from the nominal exposure by a known under- or over-exposure. The picture frame is exposed in accordance with the operator-selected exposure, and data 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 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 with the under- or over-exposure.
