Abstract
A photographic exposure control apparatus includes a directable light source, and an auxiliary shutter which is located between a camera lens and a subject. The auxiliary shutter includes a housing structure which has a window therein. The window is selectively opened and closed by a blade which is movably mounted on the housing structure, which is motor driven, and which allows the housing structure to block entry of light into a camera lens when the window is closed, and to allow light into the lens when the window is open. The method of the invention includes the steps of positioning a subject and a film-containing camera so that the subject is in the view of the camera, underexposing an image of the subject on the film, positioning an auxiliary shutter between the subject and the camera, with the auxiliary shutter in a closed condition, darkening the environment containing the subject and the camera, providing an emitted light beam which may be directed towards the subject using a light source and a fiber-optic cable which has an auxiliary shutter control button located thereon, directing the emitted light beam at the subject, opening the auxiliary shutter for a predetermined time interval with the emitted light beam directed at a particular portion of the subject, and closing the auxiliary shutter with the auxiliary-shutter control button at the end of a predetermined time interval.
