摘要 |
A flashlight photographing device wherein the possibility of missing a shutter chance is minimized, a shutter speed can be set appropriately upon trailing shutter blind synchronized photographing, and an interval of time is minimized until a subsequent photographing operation is permitted. The flashlight includes a plurality of flash devices which are controlled such that one of them which has been charged up at the earliest is caused to emit flashlight. After the charged voltage of a main capacitor of one of the flash devices becomes higher than a second predetermined value but lower than a first predetermined value at which the flash device can operate to emit light, operation of an automatic focusing motor or a film winding motor of a camera is started. When trailing shutter blind synchronized photographing is to be performed in an exposure mode wherein a shutter speed is to be automatically set, exposure of the camera is controlled in accordance with a predetermined exposure time as in bulb exposure.
