The Photo-Jumelle was developed and manufactured by Jules Carpentier, it is loosely shaped like a pair of binoculars with one lens used for focusing or viewing the other for taking the exposure. It was the first of a number of French cameras of this shape either for mono or stereo exposures and was also an early adopter of the 4.5 x 6 cm plate size which proved popular in the 1900s.

Two sizes were produced - 4.5 x 6 cm and 6.5 x 9 cm. Several variations exist:

  • 4.5 x 6 cm, fixed focus, rapid rectilinear lens, fixed aperture. The earliest model had this specification.
  • 4.5 x 6 cm, fixed focus, f6.3 Zeiss Anastigmat lens, iris diaphragm.
  • 6.5 x 9 cm, fixed focus, rapid rectilinear lens, iris diaphragm. Introduced in 1894.
  • 6.5 x 9 cm, fixed focus, f8 Zeiss Anastigmat lens, iris diaphragm. Introduced in 1894.
  • Prior to 1894 the shutter was tensioned by pulling a plate at the end of the camera front. Later a sliding pin situated between the 'lenses' was used.
  • Focusing was added to the larger models.
  • In 1895 variable shutter speeds using a pneumatic delay were added to all models except the smaller size with rapid rectilinear lens.
  • Some models have a ring on the rod used to change plates, others a small disc.

In Britain the Photo-Jumelle was retailed by The London Stereoscopic Company as the Binocular Camera. To their later models an exposure counter was added. A variant called the Daylight Binocular was also produced by L.S.C. which had a daylight loading facility and full size focusing screen.

A number of accessories were produced for the camera the most interesting being an enlarger for the smaller size which is shown in the 1892 patent.
