Maison Dubroni was a camera maker in Paris in the nineteenth century. Despite the Italian-sounding name, the company was owned by Jules Bourdin (Dubroni is an anagram of his name; a note on an auction lot at Westlicht states that his father did not want the family name associated with his photographic inventions).
Dubroni is best known for a range of cameras allowing sensitisation, development and fixing of wet collodion plates inside the camera. These are the Appareils Dubroni No. 1 - No. 6 (each seems also to have had its own name; the cited example at Westlicht is a No. 1, identified in the box lid as Photographie de Poche).
Other known cameras:
- Photo-Eclair, about 1886; a concealed camera to be worn under a waiscoat, taking five 4x4 cm photographs on a single circular plate. This was designed by J.F Fetter for Dubroni. It is very similar to the Gray/Stirn concealed camera.
- Photo-Sport (strut-folding plate camera with unpleated cloth 'bellows', about 1889)
- Folding field cameras (conventional wooden, bellows-focusing cameras)
- Not to be confused with Alessandro Duroni of Murer & Duroni.
- Dubroni Photographie de Poche outfit: camera for 4 cm round exposures on 5 cm square plates, with Dubroni Petzval lens and glass interior lining, to allow sensitisation and development of collodion plates inside the camera, sold at the fourth Westlicht Photographica Auction, in November 2003.
