Camera system for relief photography - uses two imaging objectives to obtain two adjacent film images to be projected alternately

摘要

The relief photography system employs a camera with two lenses (12a, 12b) used to obtain two images side-by-side across the film. These two images are projected alternately each image being blocked during projection of the other image. Pref. the camera employs a removable adaptor with two objective lenses (12a, 12b) used to focus respective images onto the left-hand and right hand sides of the film. Each lens (12a, 12b) may be supported by a lens mounting which has an adjustable orientation relative to the adapter. The image may be transferred from the lens to the film via optical fibres.
