A dimming plate for dimming light from an internal flash device of a camera, is disposed on the external flash device of the present invention which is mounted for use on a mounting seat of the camera. A two-lamp-lighting photographing is carried out in a state where the light from the internal flash device of the camera is dimmed by covering a luminescent unit of the internal flash device with the dimming plate of the external flash device. Thereby the two-lamp-lighting photographing can be carried out easily and reliably, where the light emission of the external flash device is used as a main light source, and the light emission of the internal flash device of the camera as a supplementary light source. The external flash device becomes inexpensive because the two-lamp-lighting photographing can be carried out only by incorporating the dimming plate therein without a special sub-luminescent unit disposed.
