ABSTRACT:
An electronic flash device is preferably powered by a high voltage, generally planar multicell battery having a low internal impedance and a high current discharge capability to enable a flash storage capacitor to be quickly charged upon the battery being directly connected to the capacitor. Actuation of a photographic cycle initiating button on an associated camera operates to directly connect the battery to the flash storage capacitor thereby enabling the capacitor to be quickly charged to its required voltage in readiness to provide an illuminating flash of light during the exposure interval which commences at a minute time after the button actuation.
