The movie camera, film camera or cine-camera is a type of photographic camera which takes a rapid sequence of photographs on strips of film. The video camera has largely replaced it for private use, but for professional purposes, 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; each image constitutes a "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.
History
Early experimentation
The first patented film camera was designed in England by Frenchman Louis Le Prince in 1888. He built and patented an earlier 16 lens camera in 1887 at his workshop in Leeds. The first 8 lenses would be triggered in rapid succession by an electromagnetic shutter on the sensitive film; the film would then be moved forward allowing the other 8 lenses to operate on the film. After much trial and error, he was finally able to develop a single lens camera in 1888, which he used to shoot the first sequences of moving film in the world, including the Roundhay Garden Scene and Leeds Bridge. According to Adolphe Le Prince, who assisted his father at Leeds, Roundhay Garden was shot at 12 frame/s and Leeds Bridge at 20 frame/s. His camera still exists with the National Media Museum in Bradford. He shot the film on celluloid with 1¾ inch width.
Another early pioneer was the British inventor William Friese-Greene. He began to experiment with the use of oiled paper as a medium for displaying motion pictures in 1885 and by 1887 he was experimenting with the use of celluloid. In 1889, Friese-Greene took out a patent for a 'chronophotographic' camera. This was 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. He gave a public demonstration in 1890 of his device, but the low frame rate combined with the device's apparent unreliability made an unfavourable impression.
William Kennedy Laurie Dickson, a Scottish inventor and employee of Thomas Alva Edison, designed the Kinetographic Camera in 1891. The camera was powered by an electric motor and was capable of shooting with the new sprocketed film. To govern the intermittent movement of the film in the camera, allowing the strip to stop long enough so each frame could be fully exposed and then advancing it quickly (in about 1/460 of a second) to the next frame, the sprocket wheel that engaged the strip was driven by an escapement disc mechanism—the first practical system for the high-speed stop-and-go film movement that would be the foundation for the next century of cinematography.
The Lumière Domitor camera was created by Charles Moisson, the chief mechanic ot the Lumière works in Lyon in 1894. The camera used paper film of 35 millimeter width, but in 1895 the Lumière brothers shifted to celluloid film, which they bought from New-York’s Celluloid Manufacturing Co. This they covered with their own Etiquette-bleue emulsion, had it cut into strips and perforated.
In 1894 the Polish inventor Kazimierz Prószynski constructed a projector and camera in one, an invention he called the Pleograph.
Mass-market
Due to the work of Le Prince, Friese-Greene, Edison and the Lumière brothers, the movie camera had become a practical reality by the mid 1890s. The first firms were soon established for the manufacture of movie camera, including Birt Acres, Eugene Augustin Lauste, Dickson, Pathé frères, Prestwich, Newman & Guardia, de Bedts, Gaumont-Démény, Schneider, Schimpf, Akeley, Debrie, Bell & Howell, Leonard-Mitchell, Ertel, Ernemann, Eclair, Stachow, Universal, Institute, Wall, Lytax, and many others.
The Aeroscope was built and patented in England in the period 1909-1911 by Polish inventor Kazimierz Prószynski. Aeroscope was the first successful hand-held operated film camera. The cameraman did not have to turn the crank to advance the film, as in all cameras of that time, so he could operate the camera with both hands, holding the camera and controlling the focus. This made it possible to film with the Aeroscope in difficult circumstances including from the air and for military purposes.
The first all-metal cine camera was the Bell & Howell Standard of 1911-12. One of the most complicated models was 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.
Home movie cameras
Movie cameras were available before World War II often using the 9.5 mm film format. The use of movie cameras had an upsurge in popularity in the immediate post-war period giving rise to the creation of home movies. Compared to the pre-war models, these cameras were small, light, fairly sophisticated and affordable. An extremely compact 35 mm movie camera Kinamo was designed by Emanuel Goldberg for amateur and semi-professional movies in 1921. A spring motor attachment was added in 1923 to allow flexible handheld filming. The Kinamo was used by Joris Ivens and other avant-garde and documentary filmmakers in the late 1920s and early 1930s.
While a basic model might have a single fixed aperture/focus lens, a better version might have three or four lenses of differing apertures and focal lengths on a rotating turret. A good quality camera might come with a variety of interchangeable, focusable lenses or possibly a single zoom lens. The viewfinder was normally a parallel sight within or on top of the camera body. In the 1950s and for much of the 1960s these cameras were powered by clockwork motors, again with variations of quality. A simple mechanism might only power the camera for some 30 seconds, while a geared drive camera might work for as long as 75 – 90 seconds (at standard speeds). Even today there is a market among collectors for these types of camera, as the engineering and materials were of a very high standard and no battery is required. While film stock and the ability to process it exists, these cameras can be used.
The common film used for these cameras was termed Standard 8, which was a strip of 16 millimetre wide film which was only exposed down one half during shooting. The film had twice the number of perforations as film for 16 mm cameras and so the frames were half as high and half as wide as 16 mm frames. The film was removed and placed back in the camera to expose the frames on the other side once the first half had been exposed. Once the film was developed it was sliced down the middle and the ends attached, giving 50-foot (15 m) of Standard 8 film from a spool of 25-foot (7.6 m) of 16 mm film. 16 mm cameras, mechanically similar to the smaller format models, were also used in home movie making but were more usually the tools of semi professional film and news film makers.
In the 1960s a new film format, Super8, coincided with the advent of battery operated electric movie cameras. The new film, with a larger frame print on the same width of film stock, came in a cassette which simplified changeover and developing. Another advantage of the new system is that they had the capacity to record sound, albeit of indifferent quality. Camera bodies, and sometimes lenses, were increasingly made in plastic rather than the metals of the earlier types. As the costs of mass production came down, so did the price and these cameras became very popular. This type of format and camera was more quickly superseded for amateurs by the advent of video cameras, although some professionals continued to make use of its visual characteristics alongside larger format film and video cameras.
