ABSTRACT:
In an electronic flash apparatus which is provided with a first discharge tube for bounce illumination and a second flash discharge tube for direct illumination, emission of flash light by the first flash discharge tube and emission of flash light by the second are arranged to separately begin and to simultaneously end to simplify complex circuit arrangement otherwise required for having the amount of light reflected by the object of flash light emission by the first discharge tube and that of flash light emission by the second discharge tube in a fixed ratio. The second discharge tube is arranged to flash without fail despite of the simplified circuit arrangement.
