Economizing on Polaroid Films

[摘要] The use of three slides, each capable of masking two of the three lenses leaving the third to make an exposure on a tri-lens Polaroid camera of a scintillation camera, is described. Successive use of the three slides during three consecutive exposures results in the recording of three projections of a study on a single print.
