If we had actually started in close to a six-foot man and then pulled the camera back until he was a speck, we would have had to track back about two thousand feet - obviously impractical…instead we photographed him on 65mm film simply tumbling about in full frame. The we front-projected a six-inch image of this scene onto a glossy white card suspended against black velvet and, using our worm-gear arrangement, tracked the camera away from the miniature screen until the astronaut became so small in the frame that he virtually disappeared. Since we were re-photographing an extremely small image there was no grain problem and he remained sharp and clear all the way to infinity.
