The Vélo-Jumelle cameras are falling-plate detective cameras, made by Hermagis in the last years of the 19th century: they are announced as new in an article in Hermagis' own short-lived quarterly magazine, L'Amateur d'Excursions Photographiques of June 1898.[1] They are described as a new model of the existing Vélocigraphe cameras, but made in the tapered jumelle shape to save some size and weight. The article stresses the speed of use of the camera, claiming that two exposures can be made per second.[1]
The camera was announced in versions for 6½x9 and 9x12 cm plates, and as stereo models for 7x15 plates (one stereo pair per plate) and 8x9 cm plates (using two plates per stereo pair; this is equivalent to a camera using 9x18 plates, but allows more convenient use of the camera for single exposures).[1] An advertisement reproduced at Collection Appareils also offers the mono camera in 13x18 cm size, but not the larger stereo camera.[2]
The camera body is of mahogany, with morocco leather covering. It has a behind-the-lens shutter with five instantaneous speeds, 1/10 - 1/200 second, plus 'B', and an f/6.8 Hermagis lens (either a Néo-stigmat or an Aplanastigmat) with helical focusing.[2] There is a folding Newton finder on the top.
