Abstract

In the disclosed arrangement, an energy storage device such as a capacitor is discharged through a flash lamp. A sensing device produces a signal when the storage voltage is sufficient to fire the lamp. A switchover device normally permits the shutter and exposure aperture to be set for daylight operation, but automatically responds to the signal to switch the shutter speed and the exposure aperture to suitable values for flash operation.
