ABSTRACT:
An image pickup apparatus capable of obtaining a satisfactory picked up image, even if a light emission device cannot emit the requested light amount. When notified that at least one of slave flash devices is unable to emit a set amount of light, a master flash device recalculates amounts of light emission of the flash devices based on a possible light emission amount of a flash device having a maximum deficiency of light amount relative to a set light emission amount, thereby maintaining light amount ratios at the time of multiple flash photographing.
