Abstract: A shutter system for a movie camera or the like which controls the exposure of film including a main shutter wheel rotatably mounted on an axis and first and second adjustable shutter wheels positioned adjacent to and coaxially rotating therewith. The first and second adjustable shutter wheels may selectively pivot relative to the main shutter wheel in opposite angular directions so as to close off a portion or all of the arcuate apertures within the main shutter wheel.
