Période

This type of camera used c. 1954+

Canada

Example of a good quality stereo camera which was used in Canada, nd made during the last popular revival period of stereo photography, the 1950s. It was originally owned by Ralph Winston Scott, Calgary AB.

Fonction

To record 2 still images simultaneously on adjacent areas of photographic film for stereoscopic (3D) viewing with appropriate viewing device.

Technique

The Iloca IIA is an example of a miniature, 35mm stereo camera. The pattern for this type of camera was set by Jules Richard's Vèrascope (1979.0101; 1981.0937). Introduced in 1894, it consisted of an all-metal body, double-lenses, and an optical viewfinder between the lenses. With only minor variations it continued to be sold until the 1930s. Although the Vèrascope was a plate camera, Richard also introduced a 35mm film stereo camera in 1914. It failed to catch on, however, and was discontinued in the 1920s. Several 35mm stereo cameras were introduced in the 1930s, but this was a period of decline for stereophotography and relatively few were sold. Stereophotography enjoyed a revival after WWII, reaching it's peak in the 1950s. The most popular stereo camera of the post-war years was the Stereo Realist, manufactured in the U.S. by David White Instrument Co.. Apart from the fact it took 35mm film, increasingly popular among amateur photographers after the war, it differed little in its general layout from the Vèrascope of 1894. Wilheim Witt, a producer of good quality 35mm cameras, introduced its first stereo cameras in 1950. The Iloca II was introduced in 1951, the company's first to use the Stereo Realist's 24 x 23 mm image size, which had become the de facto industry standard in North America. The Stereo IIA, introduced in 1954, differed from it's predecessor only in it's more modern, streamlined appearance. Both featured coupled focusing of the twin Ilitar 1:3.5/35mm lenses, shutter speeds up to 1/300 second, and a direct optical viewfinder. Due to stiff competition from cameras like the Iloca, David White Instrument Co. contracted Wilheim Witt to produce a cheaper version of its Stereo Realist. The result was the Realist 45 (1981.1184).
