ABSTRACT:
A camera having an ordinary automatic exposure function which automatically decides a proper shutter speed and f-stop based on the results of photometry is additionally provided with a slow-photography mode. When the camera is set to the slow-photography mode, a predetermined shutter speed and f-stop outside a range of shutter speeds and f-stops capable of being set by ordinary automatic exposure control is set. This makes it possible to photograph night scenes, fireworks displays and the like. Photography is possible even in a light-value region in which the camera shutter would be locked against release in ordinary automatic exposure control owing to too little light.
