Abstract
An exposure control system for a photographic camera of a type having a two-curtain type focal plane shutter. When used in combination with an electronic flash device in which the voltage stored on a capacitor is discharged through a flash tube to illuminate the target object to be photographed, this system is switched from an automatic or manual daylight exposure mode to an automatic flash exposure mode when the voltage stored on the capacitor in the flash device reaches a predetermined amount. The shutter is closed in response to the firing of the flash device.
