Vinten Model E camera used for the Biocolour two-colour proces developed by Claude Friese-Greene, the cinematographer and son of William Friese-Greene. The camera is adapted from the Vinten Model C camera, designed by William Vinten in 1919. Of all-metal construction, it has a four-lens turret, built-in pan and tilt head with differential gear mechanism, 8:1 and 1:1 drive from the same crank handle by means of a gear change, and an immediate reverse direct gear drive to both external magazines. Vinten adapted the camera for the Friese-Greene proces by changing its gearing and adding filters to the shutter. He was a director of Friese-Greene's company. General view 3/4 front, showing camera mounted on its panning head.
