ABSTRACT:
A stereoscopic picture-taking method comprises the steps of (1) positioning two image-bearing transparencies each having substantially the same positive image at separate right-position and left-position locations relative to one another; (2) projecting light through the right-positioned transparency first to a right-positioned taking lens of a camera and then to a right-positioned imaging area on a filmstrip in the camera, to expose a latent image on the right-positioned imaging area of the positive image on the right-positioned transparency; and (3) projecting light through the left-positioned transparency first to a left-positioned taking lens of the camera located to the left of the right-positioned taking lens and then to a left-positioned imaging area on the filmstrip located to the left of the right-positioned imaging area, to expose a latent image on the left-positioned imaging area of the positive image on the left-positioned transparency. Preferably, the positive image on the right-positioned transparency and the positive image on the left-positioned transparency are of a similar main subject shown in front of a similar background, with the main subject in the two transparencies being in at least slightly different locations relative to the background to appear to be viewed from at least slightly different perspectives when looking at the two transparencies.
