Chronology of cameras Demaria-Lapierre 
History of the brand Demaria-Lapierre New window

This type of camera is called a "jumelle" ( jumelle means binoculars in French) . Do not issue too quick conclusions ! This name has nothing to do with the fact that there are two lenses, but with the fact that , unlike the camera of the same timeyou hold the camera in front of your eyes , as you would with binoculars.

The "jumelles" are devices whose shape is characterized by a front plate supporting the lens and a rigid chamber in the shape of a truncated pyramid , taking the form of a bellows. They may be equipped with a interchangeable multi- plates holder. When fitted with a pair of lenses , we call them Jumelle stereo . I have already presented a jumelle , manufactured by Bellieni Nancy and a stereo model , the Glyphoscope Richard .

All controls are in front , between the two Kelar lenses. A rotating knob is used to select between an instant (which makes a klong noise ) and time exposure ( two times ) . A cursor is just below this button and allows you to cock the two shutters. The second cursor , a little lower , allows you to choose one of the three apertures. This cursor is directly welded or screwed to a perforated metal plate with six holes ( two sets of three ) that passes behind the lenses.

 The rotating knob , which directs to the values ​​1-5 , yet keeps  its mystery .
 The unit is all metal . It is heavy, but very rigid, which allows to have  a large tripod socket . There is no adjustment of distance . A viewfinder located above the unit allows framing ... approximate .

 The plate holder seems to contain about 12 plates, if we believe the counter located above .
 On the back side , a slider is used to prevent the penetration of light into the magazine. The cursor must be positioned on "open" as soon as you want to take a photo, and of course stay closed when the holder is not mounted on the housing of the camera.

 Once the photograph has been taken , you must pull on the large side handle . By a retraction game the exposed plate leaves room for a new unexposed plate . Unloading / loading the magazine must be done in a darkroom.

 At the same time , the "Detective " cameras also offered the ability to load multiple plates, but their use is more difficult ( problem of sight) and the plates have the annoying tendency to break during retraction . A jumelle is more practical than a detective camera.
