158-403: A beam splitter prism behind the camera lens. Two prints on half-thickness stock were made from the negative, one from only the red-filtered frames, the other from the green-filtered frames. After development, the silver images on the prints were chemically toned to convert them into images of the approximately complementary colors . The two strips were then cemented together back to back, forming

The standard, in some European countries, became 1.66:1 instead of 1.85:1, although some productions with pre-determined American distributors composed for the latter to appeal to US markets. In September 1953, 20th Century Fox debuted CinemaScope with their production of The Robe to great success. CinemaScope became
316-411: A niche market of enthusiasts and format lovers. Originally, film was a strip of cellulose nitrate coated with black-and-white photographic emulsion . Early film pioneers, like D. W. Griffith , color tinted or toned portions of their movies for dramatic impact, and by 1920, 80 to 90 percent of all films were tinted. The first successful natural color process was Britain's Kinemacolor (1909–1915),
395-565: A 68 mm film that used friction feed, not sprocket holes, to move the film through the camera. A court judgment in March 1902 invalidated Edison's claim, allowing any producer or distributor to use the Edison 35 mm film design without license. Filmmakers were already doing so in Britain and Europe, where Edison did not file patents. At the time, film stock was usually supplied unperforated and punched by
474-519: A SuperScope variant became the predecessor to the modern Super 35 format that is popular today. The concept behind Super 35 originated with the Tushinsky Brothers' SuperScope format, particularly the SuperScope 235 specification from 1956. In 1982, Joe Dunton revived the format for Dance Craze , and Technicolor soon marketed it under the name "Super Techniscope" before the industry settled on
553-436: 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. The standard image exposure length on 35 mm for movies ("single-frame" format) is four perforations per frame along both edges, which results in 16 frames per foot of film. A variety of largely proprietary gauges were devised for
632-442: A fairly large stretch of film: 2–3 ft or approximately 2 seconds. Also, polyester film will melt if exposed to the projector lamp for too long. Original camera negative is still made on a triacetate base, and some intermediate films (certainly including internegatives or "dupe" negatives, but not necessarily including interpositives or "master" positives) are also made on a triacetate base as such films must be spliced during
711-525: A hardened gelatin relief image was made from each negative, and the three matrices transferred color dyes into a blank film to create the print. Two-color processes, however, were far from extinct. In 1934, William T. Crispinel and Alan M. Gundelfinger revived the Multicolor process under the company name Cinecolor . Cinecolor saw considerable use in animation and low-budget pictures, mainly because it cost much less than three-color Technicolor. If color design
790-405: A holder for a roll of picture-carrying gelatin layer-coated paper. Hannibal Goodwin then invented a nitrocellulose film base in 1887, the first transparent, flexible film. Eastman also produced these components, and his was the first major company to mass-produce such film when, in 1889, Eastman realized that the dry-gelatino-bromide emulsion could be coated onto this clear base, eliminating
869-548: A lens turret in the same manner as an anamorphic lens. In contrast, the Panavision system uses a spectral comb filter system, but their combination splitter-filter-lens is physically similar to the Technicolor assembly and can be used in the same way. No other modifications are required to the projector for either system, though for the Technicolor system a silver screen is necessary, as it would be with polarised-light digital 3D. Thus

#1733093875092948-411: A number of systems had been proposed for 3D systems based on 35 mm film by Technicolor , Panavision and others. These systems are improved versions of the "over-under" stereo 3D prints first introduced in the 1960s. To be attractive to exhibitors, these schemes offered 3D films that can be projected by a standard 35 mm cinema projector with minimal modification, and so they are based on
1027-416: A programme can readily include both 2D and 3D segments with only the lens needing to be changed between them. In June 2012, Panavision 3D systems for both 35 mm film and digital projection were withdrawn from the market by DVPO theatrical (who marketed these system on behalf of Panavision) citing "challenging global economic and 3D market conditions". In the transition period centered around 2010–2015,
1106-496: A removable aperture plate in the film projector gate, the top and bottom of the frame could be cropped to create a wider aspect ratio. Paramount Pictures began this trend with their aspect ratio of 1.66:1, first used in Shane , which was originally shot for Academy ratio . It was Universal Studios, however, with their May release of Thunder Bay that introduced the now standard 1.85:1 format to American audiences and brought attention to
1185-514: A shade smaller than those now in use. This standardized film size of 1889 has remained, with only minor variations, unaltered to date". Until 1953, the 35 mm film was seen as "basic technology" in the film industry, rather than optional, despite other gauges being available. In 1908, Edison formed "a cartel of production companies", a trust called the Motion Picture Patents Company (MPPC), pooling patents for collective use in
1264-409: A single strip similar to duplitized film. In 1928, Technicolor started making their prints by the imbibition process, which was mechanical rather than photographic and allowed the color components to be combined on the same side of the film. Using two matrix films bearing hardened gelatin relief images, thicker where the image was darker, aniline color dyes were transferred into the gelatin coating on
1343-461: A standard had momentous impact on the development and spread of cinema. The standard gauge made it possible for films to be shown in every country of the world… It provided a uniform, reliable and predictable format for production, distribution and exhibition of movies, facilitating the rapid spread and acceptance of the movies as a world-wide device for entertainment and communication. When the MPPC adopted
1422-447: A third, blank strip of film. Technicolor re-emerged as a three-color process for cartoons in 1932 and live action in 1934. Using a different arrangement of a beam-splitter cube and color filters behind the lens, the camera simultaneously exposed three individual strips of black-and-white film, each one recording one-third of the spectrum , which allowed virtually the entire spectrum of colors to be reproduced. A printing matrix with
1501-482: A two-color additive process that used a rotating disk with red and green filters in front of the camera lens and the projector lens. But any process that photographed and projected the colors sequentially was subject to color "fringing" around moving objects, and a general color flickering. In 1916, William Van Doren Kelley began developing Prizma , the first commercially viable American color process using 35 mm film. Initially, like Kinemacolor, it photographed
1580-453: Is credited as the inventor of 35 mm movie film in 1889, when the Edison company was using Eastman film. The company still received film from Blair after this; at first Blair would supply only 40 mm ( 1 + 9 ⁄ 16 in) film stock that would be trimmed and perforated at the Edison lab to create 1 + 3 ⁄ 8 -inch (35 mm) gauge filmstrips, then at some point in 1894 or 1895, Blair began sending stock to Edison that

#17330938750921738-419: Is retained, minimising the need for modifications to the projector or to long-play systems. The linear speed of film through the projector and sound playback both remain exactly the same as in normal 2D operation. The Technicolor system uses the polarisation of light to separate the left and right eye images and for this they rent to exhibitors a combination splitter-polarizer-lens assembly which can be fitted to
1817-482: Is stored between the perforations on the sound side; SDDS , stored in two redundant strips along the outside edges (beyond the perforations); and DTS , in which sound data is stored on separate compact discs synchronized by a timecode track on the film just to the right of the analog soundtrack and left of the frame. Because these soundtrack systems appear on different parts of the film, one movie can contain all of them, allowing broad distribution without regard for
1896-493: Is the last remaining manufacturer of motion picture film. The ubiquity of 35 mm movie projectors in commercial movie theaters made 35 mm the only motion picture format that could be played in almost any cinema in the world, until digital projection largely superseded it. In 1880, George Eastman began to manufacture gelatin dry photographic plates in Rochester, New York . Along with W. H. Walker, Eastman invented
1975-584: The "1930 standard", studios which followed the suggested practice of marking their camera viewfinders for this ratio were: Paramount-Famous-Lasky, Metro-Goldwyn Mayer, United Artists, Pathe, Universal, RKO, Tiffany-Stahl, Mack Sennett, Darmour, and Educational. The Fox Studio markings were the same width but allowed .04 in more height. In 1932, in refining this ratio, the Academy of Motion Picture Arts and Sciences expanded upon this 1930 standard. The camera aperture became 22 by 16 mm (0.87 by 0.63 in), and
2054-503: The "Academy" ratio is referred to as having an aspect ratio of 1.33:1, it is done so mistakenly. The commonly used anamorphic format uses a similar four-perf frame, but an anamorphic lens is used on the camera and projector to produce a wider image, today with an aspect ratio of about 2.39:1 (more commonly referred to as 2.40:1). The ratio was formerly 2.35:1—and is still often mistakenly referred to as such—until an SMPTE revision of projection standards in 1970. The image, as recorded on
2133-449: The "negative assembly" process, and the extant negative assembly process is solvent-based. Polyester films are not compatible with solvent-based assembly processes. Besides black & white and color negative films, there are black & white and color reversal films , which when developed create a positive ("natural") image that is projectable. There are also films sensitive to non-visible wavelengths of light , such as infrared . In

Edison and Eastman's form of business manipulation was ruled unlawful in 1914, but by this time the technology had become the established standard. In 1917, the new Society of Motion Picture Engineers (SMPE) "acknowledged

Edison claimed exclusive patent rights to the design of 35 mm motion picture film , with four sprocket holes (perforations) per frame, forcing his only major filmmaking competitor, American Mutoscope & Biograph , to use
2370-497: The CinemaScope lenses' technical limitations with their own lenses, and by 1967, CinemaScope was replaced by Panavision and other third-party manufacturers. The 1950s and 1960s saw many other novel processes using 35 mm, such as VistaVision , SuperScope, and Technirama , most of which ultimately became obsolete. VistaVision, however, would be revived decades later by Lucasfilm and other studios for special effects work, while
2449-465: The additional optical printing stage required made this an unattractive option at the time for most film makers. However, in television production , where compatibility with an installed base of 35 mm film projectors is unnecessary, the 3-perf format is sometimes used, giving—if used with Super 35 —the 16:9 ratio used by HDTV and reducing film usage by 25 percent. Because of 3-perf's incompatibility with standard 4-perf equipment, it can utilize

2528-453: The anamorphic projection standard. This allows an "anamorphic" frame to be captured with non-anamorphic lenses, which are much more common. Up to 2000, once the film was photographed in Super 35, an optical printer was used to anamorphose (squeeze) the image. This optical step reduced the overall quality of the image and made Super 35 a controversial subject among cinematographers, many who preferred
2607-400: The aspect ratio in the computer allows the studios to perform all post-production and editing of the movie in its original aspect (1.33:1 or 1.78:1) and to then release the cropped version, while still having the original when necessary (for Pan & Scan, HDTV transmission, etc.). The non-anamorphic widescreen ratios (most commonly 1.85:1) used in modern feature films makes inefficient use of
2686-462: The available image area on 35 mm film using the standard 4-perf pulldown; the height of a 1.85:1 frame occupying only 65% of the distance between the frames. It is clear, therefore, that a change to a 3-perf pulldown would allow for a 25% reduction in film consumption whilst still accommodating the full 1.85:1 frame. Ever since the introduction of these widescreen formats in the 1950s various film directors and cinematographers have argued in favour of
2765-416: The cheap and widely-available 35 mm. Dickson said in 1933: At the end of the year 1889, I increased the width of the picture from + 1 ⁄ 2 inch to + 3 ⁄ 4 inch, then, to 1 inch by + 3 ⁄ 4 inch high. The actual width of the film was 1 + 3 ⁄ 8 inches to allow for the perforations now punched on both edges, 4 holes to the phase or picture, which perforations were

Ultimately, Prizma was refined to bipack photography, with two strips of film, one treated to be sensitive to red and the other not, running through the camera face to face. Each negative was printed on one surface of the same duplitized print stock and each resulting series of black-and-white images was chemically toned to transform
2923-435: The conventional motion picture format, frames are four perforations tall, with an aspect ratio of 1.375:1, 22 by 16 mm (0.866 by 0.630 in). This is a derivation of the aspect ratio and frame size designated by Thomas Edison (24.89 by 18.67 millimetres or 0.980 by 0.735 inches) at the dawn of motion pictures, which was an aspect ratio of 1.33:1. The first sound features were released in 1926–27, and while Warner Bros.
3002-573: The de facto status of 35mm as the industry's dominant film gauge, adopting it as an engineering standard". When film editing was done by physically cutting the film, editing the picture could only have been done on the frame line. However, the sound was stored for the whole frame between each of the four sprocket holes, and so the sound editors could cut on any arbitrary set of holes, and thus get + 1 ⁄ 4 -frame edit resolution. With this technique, an audio edit could be accurate to within 10.41 ms ." A limitation of analog optical recording

A variation developed by the Lumière brothers used a single circular perforation on each side of the frame towards the middle of the horizontal axis. When films began to be projected, several projection devices were unsuccessful and fell into obscurity because of technical failure, lack of business acumen on the part of their promoters, or both.

3555-510: The first projection device to use 35 mm, was technologically superior and compatible with the many motion pictures produced on 35 mm film. Edison bought the device in 1895–96; the Lumiere's 35 mm projection Cinematograph also premiered in 1895, and they established 35 mm as the standard for exhibition. Standardization in recording came from monopolization of the business by Eastman and Edison, and because of Edison's typical business model involving
3634-562: The higher image quality and frame negative area of anamorphic photography (especially with regard to granularity ). With the advent of digital intermediates (DI) at the beginning of the 21st century, however, Super 35 photography has become even more popular, since everything could be done digitally, scanning the original 4-perf 1.33:1 (or 3-perf 1.78:1) picture and cropping it to the 2.39:1 frame already in-computer, without anamorphosing stages, and also without creating an additional optical generation with increased grain. This process of creating

The film Anything Else (2003) was the first to be released with only cyan tracks. To facilitate this changeover, intermediate prints known as "high magenta" prints were distributed. These prints used a silver plus dye soundtrack that were printed into

Scholar Paul C. Spehr describes the importance of these developments: The early acceptance of 35 mm as
3871-421: The industry could change over completely over the course of ten-years. However, the movie industry did not make the change mainly because it would have required the modification of the thousands of existing 35 mm projectors in movie theaters all over the world. Whilst it would have been possible to shoot in 3-perf and then convert to standard 4-perf for release prints the extra complications this would cause and
3950-582: The industry making such a change. The Canadian cinematographer Miklos Lente invented and patented a three-perforation pull down system which he called "Trilent 35" in 1975 though he was unable to persuade the industry to adopt it. The idea was later taken up by the Swedish film-maker Rune Ericson who was a strong advocate for the 3-perf system. Ericson shot his 51st feature Pirates of the Lake in 1986 using two Panaflex cameras modified to 3-perf pulldown and suggested that

For a time, these various ratios were used by different studios in different productions, but by 1956, the aspect ratio of 1.85:1 became the "standard" US format. These flat films are photographed with the full Academy frame , but are matted (most often with

The gauge has been versatile in application. It has been modified to include sound, redesigned to create a safer film base , formulated to capture color, has accommodated a bevy of widescreen formats, and has incorporated digital sound data into nearly all of its non-frame areas. Eastman Kodak , Fujifilm and Agfa-Gevaert are some companies that offered 35 mm films. As of 2015, Kodak

The success of digitally projected 3D movies in the first two decades of the 21st century led to a demand from some theater owners to be able to show these movies in 3D without incurring the high capital cost of installing digital projection equipment. To satisfy that demand,
4266-463: The name Super 35. The central driving idea behind the process is to return to shooting in the original silent "Edison" 1.33:1 full 4-perf negative area (24.89 by 18.67 millimetres or 0.980 by 0.735 inches), and then crop the frame either from the bottom or the center (like 1.85:1) to create a 2.40:1 aspect ratio (matching that of anamorphic lenses) with an area of 24 by 10 mm (0.94 by 0.39 in). Although this cropping may seem extreme, by expanding
4345-490: The negative and print, is horizontally compressed (squeezed) by a factor of 2. The unexpected success of the Cinerama widescreen process in 1952 led to a boom in film format innovations to compete with the growing audiences of television and the dwindling audiences in movie theaters. These processes could give theatergoers an experience that television could not at that time—color, stereophonic sound and panoramic vision. Before

The cropped frame is then converted at the intermediate stage to a 4-perf anamorphically squeezed print compatible with
4503-542: The numerous camera and projection systems being developed independently in the late 19th century and early 20th century, as well as a variety of film feeding systems. This resulted in cameras, projectors, and other equipment having to be calibrated to each gauge. The 35 mm width, originally specified as 1 + 3 ⁄ 8 inches, was introduced around 1890 by William Kennedy Dickson and Thomas Edison , using 120 film stock supplied by George Eastman . Film 35 mm wide with four perforations per frame became accepted as
4582-477: The older screen ratio of 1.33:1. Furthermore, every theater chain had their own house aperture plate size in which the picture was projected. These sizes often did not match up even between theaters and studios owned by the same company, and therefore, uneven projection practices occurred. In November 1929, the Society of Motion Picture Engineers set a standard aperture ratio of 0.800 in by 0.600 in. Known as

Another common ITC trait was to feature an American actor, in this case Michael Quinn, in a leading role, in the hope of increasing the chances of international sales. In the second series Neil Hallett sometimes replaced Quinn and in the third series Quinn was entirely replaced by the Australian actor Ray Barrett . Ray Austin , stunt director for
4740-749: The paper. With the advent of flexible film, Thomas Edison quickly set out on his invention, the Kinetoscope , which was first shown at the Brooklyn Institute of Arts and Sciences on May 9, 1893. The Kinetoscope was a film loop system intended for one-person viewing. Edison, along with assistant William Kennedy Dickson , followed that up with the Kinetophone , which combined the Kinetoscope with Edison's cylinder phonograph . Beginning in March 1892, Eastman and then, from April 1893 into 1896, New York's Blair Camera Co. supplied Edison with film stock. Dickson
4819-471: The patent system: Eastman and Edison managed their film patents well – Edison filed the 35 mm patent in 1896, the year after Dickson left his employ – and so controlled the use and development of film. Dickson left the Edison company in 1895, going on to help competitors produce cameras and other film gauges that would not infringe on Edison's patents . However, by 1900, filmmakers found it too expensive to develop and use other gauges, and went back to using

#17330938750924898-552: The projected image would use an aperture plate size of 0.825 by 0.600 in (21.0 by 15.2 mm), yielding an aspect ratio of 1.375:1. This became known as the " Academy " ratio. Since the 1950s the aspect ratio of some theatrically released motion picture films has been 1.85:1 (1.66:1 in Europe) or 2.35:1 (2.40:1 after 1970). The image area for "TV transmission" is slightly smaller than the full "Academy" ratio at 21 by 16 mm (0.83 by 0.63 in), an aspect ratio of 1.33:1. Hence when

By the mid-2010s, most of the theaters across the world had been converted to digital projection, while others continued running 35 mm projectors. In spite of the uptake in digital projectors installed in global cinemas, 35 mm film remains in

Most if not all film prints today are made from synthetic polyester safety base (which started replacing Triacetate film for prints in the early 1990s). The downside of polyester film is that it is extremely strong, and, in case of a fault, will stretch and not break–potentially causing damage to the projector and ruining

An improved version in 1952 was quickly adopted by Hollywood, making the use of three-strip Technicolor cameras and bipack cameras (used in two-color systems such as Cinecolor ) obsolete in color cinematography. This "monopack" structure is made up of three separate emulsion layers, one sensitive to red light, one to green and one to blue. Although Eastman Kodak had first introduced acetate -based film, it

The analogue optical track technology has also changed: in the early years of the 21st century, distributors changed to using cyan dye optical soundtracks instead of applicated tracks, which use environmentally unfriendly chemicals to retain a silver (black-and-white) soundtrack. Because traditional incandescent exciter lamps produce copious amounts of infrared light , and cyan tracks do not absorb infrared light, this change has required theaters to replace
5609-620: The studios' commercial perspective with the advent of Technicolor , whose main advantage was quality prints in less time than its competitors. In its earliest incarnations, Technicolor was another two-color system that could reproduce a range of reds, muted bluish greens, pinks, browns, tans and grays, but not real blues or yellows. The Toll of the Sea , released in 1922, was the first film printed in their subtractive color system. Technicolor's camera photographed each pair of color-filtered frames simultaneously on one strip of black-and-white film by means of
5688-453: The use of "over-under" film prints. In these prints a left-right pair of 2.39:1 non-anamorphic images are substituted for the one 2.39:1 anamorphic image of a 2D "scope" print. The frame dimensions are based on those of the Techniscope 2-perf camera format used in the 1960s and 1970s. However, when used for 3D the left and right frames are pulled down together, thus the standard 4-perf pulldown
5767-480: The whole negative area between the perforations ( Super 35 mm film ) without worrying about compatibility with existing equipment; the Super 35 image area includes what would be the soundtrack area in a standard print. All 3-perf negatives require optical or digital conversion to standard 4-perf if a film print is desired, though 3-perf can easily be transferred to video with little to no difficulty by modern telecine or film scanners . With digital intermediate now
5846-442: Was carefully managed, the lack of colors such as true green could pass unnoticed. Although Cinecolor used the same duplitized stock as Prizma and Multicolor, it had the advantage that its printing and processing methods yielded larger quantities of finished film in less time. In 1950, Kodak announced the first Eastman color 35 mm negative film (along with a complementary positive film) that could record all three primary colors on
5925-403: Was common practice at the time, most of the foreign settings are depicted by combining stock footage with scenes shot on sets, in this case at Independent Artists Studios at Beaconsfield and Associated British Elstree Studios . The music for the show was by Philip Green . The show was produced by ITC Entertainment with Rank Organisation TV and ATV . It was the first ITC show filmed to fit
6004-540: Was cut exactly to specification. Edison's aperture defined a single frame of film at four perforations high. Around 1896, a 35mm projector known as a "photo-rotoscope" was made by W. C. Hughes in London , which advanced the film by means of a "dog" motion. For a time, it had been generally assumed that Dickson was following cinematography formats established by Eastman in producing the film, but Eastman had produced film in sheets that were then cut to order. Dickson used
6083-443: Was far too brittle and prone to shrinkage, so the dangerously flammable nitrate-based cellulose films were generally used for motion picture camera and print films. In 1949 Kodak began replacing all nitrocellulose (nitrate-based) films with the safer, more robust cellulose triacetate -based "Safety" films. In 1950 the Academy of Motion Picture Arts and Sciences awarded Kodak with a Scientific and Technical Academy Award ( Oscar ) for
6162-412: Was the audio frequency would cut off, in a well-maintained theater, at around 12 kHz . Studios would often record audio on the transparent film strips, but with magnetic tape on one edge; recording audio on full 35 mm magnetic tape was more expensive. Three different digital soundtrack systems for 35 mm cinema release prints were introduced during the 1990s. They are: Dolby Digital , which
6241-465: Was using synchronized phonograph discs ( sound-on-disc ), Fox placed the soundtrack in an optical record directly on the film ( sound-on-film ) on a strip between the sprocket holes and the image frame. "Sound-on-film" was soon adopted by the other Hollywood studios, resulting in an almost square image ratio of 0.860 in by 0.820 in. By 1929, most movie studios had revamped this format using their own house aperture plate size to try to recreate
