摘要： Photographic apparatus having both automatic and manual modes of operation is adapted for coupling to a microscope. the apparatus includes a viewfinder for viewing a scene in the microscope and an exposure controlling photometer for measuring the scene brightness. In addition, a rotatably mounted disc shutter is provided having an opening therein for generating a photographic image producing exposure interval and having a pair of mirrors supported thereon for movement therewith, for respectively directing image-bearing scene light to the viewfinder and to the photometer prior to an exposure. In the automatic mode, movement of the disc shutter is under the control of a microprocessor whereas in the manual mode, such movement is under operator control.
