Dr Miethe's Dreifarben-Kamera (Dr Miethe's Three-colour Camera) is a plate camera for colour-separation photography. It was designed by Dr Adolf Miethe and made by Bermpohl of Berlin, in about 1902. Three successive exposures are made onto monochrome plates, through red, green and blue filters, to make component negative images for colour printing. The camera differs little from a normal folding plate camera, except for the provision of the filters, and a repeating back to accept dark slides holding three plates side by side, to facilitate making the three exposures with minimal delay.

The camera is wooden-bodied (mahogany) with brass fittings. It has rack-and-pinion focusing on the bed. It was made in at least two sizes:

  • 7.5x8.5 cm plates[1] The example cited is shown with the repeating back arranged vertically (the larger example below is shown with the back horizontal); it is not clear whether the repeating back can be rotated, though this would clearly be desirable. There does not appear to be a shutter; presumably a roller shutter could be mounted in front of the lens.
  • 13x18 cm plates[2] This camera has a green cloth bellows with leather (or leatherette) reinforced corners.
