No doubt this news item generated a spirited hullabaloo and no small degree of consternation among movie bloggers in February, 1935.
Paris, Feb. 4., Louis Lumiere, aged 81, who 42 years ago invented one of the earliest moving picture cameras, has now devised a stereoscopic film. The apparatus includes a camera with two lenses which takes pictures at slightly different angles so that the pictures, when projected on to the screen, have the effect of solidity. Some of the spectators at a secret demonstration of the invention at the week-end consider that the invention may revolutionize cinema throughout the world.
