Abstract
A camera has a body having an exposure frame surrounding an exposure opening. The exposure frame has a window. A mask core is mounted in the body. The mask core has an axis of rotation extending transverse to the exposure frame. The mask core has a plurality of sectors arranged about the axis of rotation. Each sector has an active position adjoining the window. Each sector shades the window differently in the respective active position. A drive is coupled to the mask core. The drive selectively rotates the mask core between the active positions of each of the sectors.
