摘要: A photographic cropper comprises a pair of opposable right-angle portions, each of which contains alternating transversely spaced strips of oppositely magnetized material extending parallel to edges of that portion. The right-angle portions are continuously adjustable relative to each other in the direction of the strips and are relatively adjustable in a direction perpendicular to the strips in equally spaced steps corresponding to the spacing between similarly magnetized strips of each portion.
