Abstract
Abstract The present device comprises a mirror means rotatably mounted on a flash unit whereby the mirror lies in a partially rotatable marquee posture, protruding from the front side of an automatic electronic flash unit, over the sensor unit. The mirror housing can be rotated in response to the flash unit being rotated so that light which has been bounced from one or more surfaces, before reflecting from the subject to be photographed, is reflected from the mirror surface to the sensor unit for the purpose of controlling the duration of the flash to effect a proper exposure of the film.
