发明名称 Lens attachment for multiple imaging and vignetting
摘要 A multiple imaging attachment 26 is provided to be utilized with a camera 10 to achieve desired multiple imaging and vignetting effects. The multiple imaging attachment 26 includes a housing 54 having an opening 60 formed therein. Light is transmitted through the opening 60 to a lens 12 to expose the camera film frame. A mask 64 is provided which transmits light to selected portions of the camera film frame. The mask 64 is movable in tracks 70 along a predetermined diagonal path in the housing 54 to permit exposure of second selected portions of the camera film frame. The mask 64 can then be rotated by a coupler housing 30 to permit light to be transmitted to expose third selected portions of the film frame.
