In a previous post I wrote about stereoviews published by Jules Richard. However, he was better known as an innovator and builder of devices. His introduction of the compact 45x107 and 6x13 formats in 1893 was decisive for the success of French stereoscopy at the beginning of the 20th century. He launched a wide range of stereo cameras, stereoscopes and accessories in various price ranges.
The Glyphoscope was an alternative to the more expensive Vérascope camera. It made stereo photography accessible for amateurs. The marketing slogan was: “Établi tout spécialement pour les débutants en photographie” (designed especially for beginners in photography). The camera was sold from 1905 until the end of the 1930s without changing significantly in design.
Three models of the camera were available. They offered the same functionality but differed by shape, used materials and weight. The models 1 and 2 where made of bakelite and weighed 430 and 345 grams. Model 3 was made of wood and weighed 320 grams. A catalogue from 1913 shows all three models for the 45x107 format. Glyphoscopes that supported the 6x13 format were introduced later but were more rare.
The camera's features:
- Two achromatic, fixed focussing lenses with a focal length of 54mm
- Three diaphragm settings: position 0 (large diaphragm), position 1 (increasing 2 stops) and position 2 (increasing 4 stops)
- A guillotine shutter with two settings: P and I
- A folding crosshair viewfinder
To turn the camera into a stereoscope, the front panel with the shutter needs to be removed. A slide holder for stereoviews, fitted with an opaque glass, replaces the standard plate holder at the back. The Glyphoscope as stereo viewer works quite well, but it doesn't offer the same ease of use and viewing experience as a dedicated handheld stereoscope.
