ABSTRACT:
In the arrangement disclosed, a photographic camera operates both with an electronic flash that generates a charge completion signal and a flash without a charge completion signal. In the camera, two switching elements shift between a time constant set for the flash with the charge completion signal and a second time for a flash without the charge completion signal. A control signal responds to the time constant circuit to control an exposure in response to the time constant circuit.
