ABSTRACT OF DISCLOSURE A multiple imaging attachment is provided for achieving proper multiple imaging when the amount of light is changed to expose different positions of a film frame. The multiple imaging attachment 30 is coupled to a camera 10 so that an opening 60 in the multiple imaging attach- ment will transmit light to a lens 14 and the opening 60 in the multiple imaging attachment will transmit light to a lens 14 and the opening 60 is rotatable to direct light to selected portions of the lens 14 to expose selected portions of the film frame. The mask 64 is slidably mounted to move along a predetermined path transverse to the camera lens 14 to maintain a defined relationship between the mask and the lens and compensate for the changes in light. When the amount of light is changed while exposing different selected portions of a file frame, the mask is selectively moved to maintain the defined relationship between the mask and the lens, thereby assuring the necessary blending and overlapping between adjacent exposures to provide proper multiple imaging.
