Abstract
PURPOSE:To automatically control the quantities of light emission of respective flash devices by so constituting a titled adapter that the quantity of the reflected light from a subject is integrated and the ratios of contribution of the plural flash devices to a photograph are set arbitrarily. CONSTITUTION:An adapter 5 is so constituted that it integrates the quantity of the reflected light from a subject 6, that it segments the integrated value to provide correct exposure to the number of flash devices, that the ratios between the respective segments are determined in accordance with the ratios of contributions of respective flash devices to a photograph, that for example one flash device 1 is allowed to emit light, and when the integrated light of the quantity of the reflected light from the subject 6 by its lighting light attains the value having been determined for said device 1, the light emission of said device 1 is stopped by a comparator, etc. that the next flash device 2 is allowed to emit light and when the integrated value of the quantity of the reflected light by the lighting of said device 2 reaches the prescribed value, the light emission is stopped and that the 3rd flash device 3 is allowed to emit light and the light emission and stopping of the flash devices are thereafter controlled successively.
