Series production of pseudo-relief photographs - using pairs of displaced copies photographed after alignment in simple jig

摘要

Photographs in psuedo-relief are produced by the exposure of a positive and negative of the same scene superimposed with a slight shift between them. The adjustment of the two originals with the necessary displacement is controlled to facilitate the series production of numbers of exposures of constant quality. The original (8) and the film (6) are supported on a surface (28) having a lower stop rising to, at most, the height of the first original (8) for its lateral alignment and an upper stop to align the upper original (10).
