Appareil Dubroni
The Appareil Dubroni is a box camera for wet collodion plates. It was invented by Jules Bourdin and was produced from 1864 to 1870. "Dubroni" is an anagram of the name Bourdin; notes to an auction lot at Westlicht state that Bourdin's father did not want the family name associated with his invention.[1] The interior of this camera is lined with glass or porcelain so that sensitization, development and fixing of each plate can be done inside the camera; this was the first camera to use such a system.[1] The chemical solutions were put into and out of the camera with a bulb pipette. There is a large red window in the back of the camera, with a swivelling metal cover (or a hinged wooden one in some models), so that operations inside the camera can be viewed.[2]
The camera was made in four sizes:[2]
- No. 1, or Photographie de Poche, for 4 cm round exposures on 5 cm square plates[1]
- No. 2, for 5x5 cm or 4.5x5 cm exposures
- No. 3, or Photographie de Salon, for 7x9 cm oval exposures (very suitable for portraits)[3][4]
- No. 4, for 8x10 cm or 9x10 cm exposures
Early Photography shows a No. 1 camera in some detail, and explains the processing sequence.[2]
Dubroni also made more conventional cameras.
