Speed-O-Matic  / Dover

 

 

 

 

This is the Speed-O-Matic camera made in Boston USA

Used the Old known principle of the Instant developing film. Several manufacturers have used the same idea before.

It came to the market together the much more known and better succeed Polaroid of Mr. Edwin Land .

The year was 1948. This camera would replicate the old known Dubroni* of 1880.

The Speed-O-Matic had an Extinction meter Nº 1 to 5 near the finder. One must place the read value on the shutter dial for the right lens openings.

The 12 pictures film cartridge is placed in the back of the camera and each taken picture gets out of the camera in a closed envelope and is developed and further fixed in the furnished tank, one at a time. The film is of direct positive type, so the full developing operation needed four chemical stages, Developing, Whitening, Redeveloping and Fixing, not to count washing on the current water needed, totalizing eleven operator’s actions, and that for each of the pictures taken.   

Difficulties in furnishing the proper film pack and chemicals led the enterprise to a commercial fiasco.

But this camera reborn as the Dover now using conventional 620 film for 16  6x4.5cm  pictures.

And the Speed-O-Matic Corporation became Dover Film Corpotration.

This new camera has now the same body and extinction meter The same shutter and lens but incorporates an yellow filter, a close-up lens and a flash gun.

 

A well illustrated table guides the photographer.

 

 

 

 

Dubroni*

 

Cameras of 1880 made by the French constructor Jules Burdin.

Intended for use with Humid Collodium, these cameras were made with wooden outside construction with ceramic internals. Developing chemestry was placed through the top hole of the camera via a rubber ball pear. The camera was then tilted to receive the developing and further fixing baths. The plates were placed in the focal plane of the camera which had a sealing rubber and the rear door had strong spring system in order to maintain completely fluid proof.
