ABSTRACT:
An apparatus for changing a size of a camera's photographing aperture, which defines an image area on a film, includes a mechanism for intercepting light within the photographing aperture. The light intercepting mechanism is movable between a retracted position, in which the aperture is fully opened, and a projected position, in which the aperture is partly covered. The apparatus further includes an association mechanism which moves the light intercepting mechanism between the retracted position and the projected position. At least a forward most projecting edge of the light intercepting mechanism is moved towards the film when the light intercepting mechanism is moved into the projected position.
