Movie Cameras

The movie camera is a type of photographic camera which takes a rapid sequence of photographs on strips of film which was very popular for private use in the last century until its successor, the video camera, replaced it. Many of these cameras today have become collectors items and there is a small but well organized group of fans of these devices who use and maintain these cameras as hobby or a special interest, even if they went out of productions a long time ago. For professional purposes however, movie cameras are used and produced today, especially for the production of full feature movies. In contrast to a still camera, which captures a single snapshot at a time, the movie camera takes a series of images; "frame". This is accomplished through an intermittent mechanism. The frames are later played back in a movie projector at a specific speed, called the "frame rate" (number of frames per second). While viewing, a person's eyes and brain merge the separate pictures together to create the illusion of motion.

One of the first patented motion-picture film cameras was designed by Louis Le Prince in 1888. It still exists with the National Media Museum, England. Le Prince employed paper bands and celluloid film from John Carbutt and or Blair & Eastman in 1¾ inch width. One of the first known motion picture camera that actually worked was created by Thomas Alva Edison Template:Please clarify.

On June 21, 1889, William Friese-Greene was issued patent no. 10131 for his 'chronophotographic' camera. It was apparently capable of taking up to ten photographs per second using perforated celluloid film. A report on the camera was published in the British Photographic News on February 28, 1890. On 18 March, Friese-Greene sent a clipping of the story. Friese-Greene gave a public demonstration in 1890 but the low frame rate combined with the device's apparent unreliability failed to make an impression.

Georges Demenÿ, employee with Etienne Jules Marey, constructed the Beater Movement in 1893. The film width is 60 mm.

In 1894 Polish inventor Kazimierz Prószyński constructed Pleograph projector and camera in one, and in 1898 most advanced biopleograf.

Max Skladanowsky conceived his own make of camera in 1894-95, but more interesting is his “Bioscop” projector, the first duplex construction in practice. Green, part designer for Prestwich, also designed a duplex projecting machine. This 1896 wide-film projector can be seen at the South Kensington Science Museum.

The Lumière Domitor camera was originated by Charles Moisson, chief mechanic of the Lumière works at Lyon in 1894. They shot on paper film of 35 millimeter width. In 1895 the Lumière could buy celluloïd film from New-York’s Celluloid Manufacturing Co. This they covered with their own Etiquette-bleue emulsion, had it cut into strips and perforated. It is not known which recipe they used for positives.

Then an ever increasing number of cine cameras came up. The makes and brands would be: Birt Acres (1894–95), the Latham Eidoloscope by Lauste (1895), the Marvin & Casler Bioscope by Dickson (1895), Pathé frères (1896) with ratchet claws, Prestwich (1896), Newman & Guardia (1896), de Bedts, Gaumont-Démény (1896), Schneider, Schimpf, Akeley, Debrie, Bell & Howell, Leonard-Mitchell, Ertel, Ernemann, Eclair, Stachow, Universal, Institute, Wall, Lytax, and many others.

The first all-metal cine camera is the Bell & Howell Standard of 1911-12. One of the most complicated models is the Mitchell-Technicolor Beam Splitting Three-Strip Camera of 1932. With it, three colour separation originals are obtained behind a purple, a green, and a red light filter, the latter being part of one of the three different raw materials in use.

In 1923 Eastman Kodak introduced a 16mm film stock, principally as a lower cost alternative to 35mm and several camera makers launched models to take advantage of the new market of amateur movie-makers. Thought initially to be of inferior quality to 35mm, 16mm cameras continue to be manufactured today by the likes of Bolex, Arri and Aaton many in the Super 16mm and Ultra 16mm formats.

The most popular 35 mm cameras in use today are Arri/Arriflex, Moviecam (now owned by the Arri Group), and Panavision models. For very high speed filming, PhotoSonics are used.

Famous quotes containing the words cameras and/or movie:

    While the music is performed, the cameras linger savagely over the faces of the audience. What a bottomless chasm of vacuity they reveal! Those who flock round the Beatles, who scream themselves into hysteria, whose vacant faces flicker over the TV screen, are the least fortunate of their generation, the dull, the idle, the failures . . .
    Paul Johnson (b. 1928)

    It was easy to recognize in him the anti-social animus of a born evangelist, but there was also something else—a kind of voluptuous delight in the shabby and preposterous, a perverted aestheticism like that of a latter-day movie or radio fan, a wild will to roll in and snuffle balderdash as a cat rolls in and snuffles catnip.
    —H.L. (Henry Lewis)
