Abstract

A control circuit for operating a camera in the B shutter mode includes a microcontroller for computing an appropriate film exposure time period based on a measurement of ambient light in a scene to be photographed. Under the control of a user-actuated shutter switch, the microcontroller opens the camera shutter, counts off the computed exposure time period, and closes the shutter at the end thereof. The control circuit includes the capability of permitting the user to compensate the computed exposure time period, abort the computed exposure time period, end the computed exposure time period prematurely, and select an exposure time period in place of the computed exposure time period. Exposure times are displayed to facilitate user compensation, premature conclusion, and independent selection of the film exposure time period, in order to facilitate successful practice of time exposure photography.
