Region: Germany    Period: 1890–1930    Occupation: Instrument maker   Tag: Indupor

Stereo-Indupor-Gesellschaft was founded in 1920 by the photographer Alfred Krauth and Carl Neithold. The company was based in Frankfurt am Main. Stereo-Indupor developed a new system centred on the 9 x 12 cm format. The Indupor system comprised stereo cameras, stereoscopes, and accessories, including frames for stereoviews. With this system, the company targeted applications in portrait and industrial stereo photography. Stereo-Indupor also published and sold sets of stereoviews.

The choice of the large 9 x 12 format was notable, as the preceding decades had seen a trend towards smaller formats such as 45 x 107 and 6 x 13. The Indupor system achieved mixed success. The stereo cameras are rare today, which indicates limited commercial success. The folding stereoscope, however, was highly successful. The viewer was produced on a large scale, and many rebranded, and possibly imitated, versions are known. The front panel of the viewer was used in the company’s logo.
