Lascelles Davidson
Description
“Apparently, associated with W. Friese-Greene, in the same year, Captain William Norman Lascelles-Davidson, also of Brighton, patented a triple lens motion picture camera (E.P. 23,863, 1898). The colour filters revolved either behind the lenses, or just in front of the film, or the diaphragms might revolve, or slide synchronously with the film, or with the positive in a similar projector. This camera anticipated the work of Frederick Marshall Lee, of Walton, and Edward Raymond Turner, of Hounslow, to whom is usually accorded the credit of achieving the first practical results in additive projection.”
