The books used simple line drawing illustrations and occasionally a photo gallery insert printed on glossy paper. The book has over 200 pages of information on all aspects of stereo. I believe it is long out of print, but you may come across a used copy in your travels. Interest in stereo has cycled throughout the history of photography. When it is in a quiet stage, enthusiasts struggle to find cameras and projectors to make stereo images and shows.
Some skilled practitioners create stereo equipment, others track down used gear.
Another approach, represented by the products of RBT of Germany, is to make stereo cameras by combining two standard 35mm cameras. The result is a very effective camera with modern features. For example, the Konica Hexar cameras are used to make the popular RBT S1. Jon represents RBT in New England. This year we have the pleasure of seeing a lecture and show presented by Jon showing both the RBT cameras and their images.
