Beskrivning:

A 3-strip Technicolor camera from the 1930s. Two strips of 35 mm black and white film negative, one sensitive to blue light and the other to red light, ran together through an aperture behind a magenta filter, which allowed blue and red light to pass through. A third film strip of black and white film negative ran through a separate aperture, behind a green filter. The two apertures were positioned at 90 degrees to each other, and a gold-flecked mirror positioned at 45 degrees behind the lens allowed 1/3 of the incoming light to go directly through to the green-filtered aperture, and reflected the remaining light to the magenta-filtered aperture. Because of this division of light between three film strips, Technicolor photography required much more lighting than black and white photography. The camera is seen here without its sound-proofing "blimp" cover, which doubled its size. Photo taken at the Museum of the Moving Image, in Astoria, Queens, New York.
