摘要

Stereoscopic photographic equipment (22) allows two right and left stereoscopic photographs to be made in the first (1R) and third (1L) exposure of a continuous film (21) and then two right and left stereoscopic photographs in the second (2R) and fourth (2L) exposure of the film. Positions of perforations of first and fourth exposures are symmetrical relative to center in longitudinal direction of first exposure to the fourth exposure.
