The '''Photosphère''' is a plate camera designed for use in tropical regions, and therefore, unusually for the time, made of metal. The body is brass, with a silver-coloured plating, usually very tarnished. The front of the body has an unusual hemispherical shape. Within this, the shutter has a hemispherical blind with a hole, which swings under spring tension to make the exposure. The shutter speed is variable by changing the spring tension. Napoléon Conti patented the camera in 1888. About 4000 pieces (all variants together) were made. | The '''Photosphère''' is a plate camera designed for use in tropical regions, and therefore, unusually for the time, made of metal.

The Photosphère is a plate camera designed for use in tropical regions, and therefore, unusually for the time, made of metal. The body is brass, with a silver-coloured plating, usually very tarnished. The front of the body has an unusual hemispherical shape. Within this, the shutter has a hemispherical blind with a hole, which swings under spring tension to make the exposure. The shutter speed is variable by changing the spring tension. Napoléon Conti patented the camera in 1888. About 4000 pieces (all variants together) were made.
Different plate holders could be attached: double dark-slides made of mahagony[1] or steel, or a twelve-plate metal magazine, or roll-film holder.[2][3]
