High Speed Photography - With The Lid Off. A camera which can take eighty photographs in one five-thousandth of a second - equivalent to 24 million a minute - is shown at the Physical Society Exhibition at South Kensington, London, today. Mr. E.W. Walker, leader of the team which developed the camera, is explaining the mechanism to Miss Wendy Whitchell of Shepherd's Bush. The Kerr Cell Cine Camera, from the Armament Research Establishment, is claimed as the fastest high definition camera in the world. It is used for studying details of explosions and throws the images on to a stainless steel mirror revolving 150,000 times a minute. The image is reflected from this through small lenses on to film. (The image can be seen as series of dots on the right-hand edge of the camera). London, England. 05 April 1951.
