35 mm film is a film gauge used in filmmaking, and the film standard. [1] In motion pictures that record on film, 35 mm is the most commonly used gauge. The name of the gauge is not a direct measurement, and refers to the nominal width of the 35 mm format photographic film, which consists of strips 1.377 ± 0.001 inches (34.976 ± 0.025 mm) wide.
Edge of a 35mm film print showing the soundtracks. The outermost strip (left of picture) contains the SDDS track as an image of a digital signal; the next contains the perforations used to drive the film through the projector, with the Dolby Digital track (grey areas) with the Dolby Double-D logo, between them. The two tracks of the analog ...
A 35 mm optical printer with two projector heads, used in producing movie special effects. Starting from the left, light is shining from the lamp house, then at A is the first projector's film gate, at B a lens that projects the film in A onto the second projector's gate C.
Most of the inventions which led to optical sound-on-film technology employed the use of an electric lamp, called an 'exciter', shining through a translucent waveform printed on the edge of a film strip. When the light shines through the film, it is read by a photo-sensitive material and fed through a processor which converts the photovoltaic ...
In this workflow, the answer print is generated digitally and then written out to the IP stage using a laser film printer [11] known as a film recorder. Due to the specialized nature of the exposure and the higher degree of control afforded by the film lab equipment, these intermediate and release stocks are specially designed solely for these ...
A common workflow for film editing involves edge-coding printed film simultaneously with the film's synchronized audio track, on 35mm magnetic film, so that a foot of film and its synchronized audio have identical edge numbers. Eastman Kodak began using latent image edge numbering on their manufactured 35mm raw film stocks in 1919. [1] [2]
The film is usually placed in close contact with phosphor screen(s) and/or thin lead-foil screen(s), the combination having a higher sensitivity to X-rays. Because film is sensitive to x-rays, its contents may be wiped by airport baggage scanners if the film has a speed higher than 800 ISO. [ 32 ]
