16 mm film

Last updated

16 mm film is a historically popular and economical gauge of film. 16 mm refers to the width of the film; other common film gauges include 8 and 35 mm. It is generally used for non-theatrical (e.g., industrial, educational) film-making, or for low-budget motion pictures. It also existed as a popular amateur or home movie-making format for several decades, alongside 8 mm film and later Super 8 film. Eastman Kodak released the first 16 mm "outfit" in 1923, consisting of a camera, projector, tripod, screen and splicer, for US$335 (equivalent to US$5,088in 2020). [1] RCA-Victor introduced a 16 mm sound movie projector in 1932, and developed an optical sound-on-film 16 mm camera, released in 1935. [2]

History

Eastman Kodak introduced 16 mm film in 1923, as a less expensive alternative to 35 mm film for amateurs. During the 1920s, the format was often referred to as sub-standard by the professional industry. [3]

Kodak hired Willard Beech Cook from his 28 mm Pathescope of America company to create the new 16 mm 'Kodascope Library'. In addition to making home movies, people could buy or rent films from the library, a key selling aspect of the format.

Intended for amateur use, 16 mm film was one of the first formats to use acetate safety film as a film base. Kodak never used nitrate film for the format, owing to the high flammability of the nitrate base. 35 mm nitrate was discontinued in 1952.

Production evolution

The silent 16 mm format was initially aimed at the home enthusiast, but by the 1930s it had begun to make inroads into the educational market. The addition of optical sound tracks and, most notably, Kodachrome in 1935, gave an enormous boost to its popularity. The format was used extensively during World War II, and there was a huge expansion of 16 mm professional filmmaking in the post-war years. Films for government, business, medical and industrial clients created a large network of 16 mm professional filmmakers and related service industries in the 1950s and 1960s. The advent of television production also enhanced the use of 16 mm film, initially for its advantage of cost and portability over 35 mm. At first used as a news-gathering format, the 16 mm format was also used to create television programming shot outside the confines of the more rigid television studio production sets. The home movie market gradually switched to the even less expensive 8 mm and Super 8 mm film formats.

16 mm, using light cameras, was extensively used for television production in many countries before portable video cameras appeared. In Britain, the BBC's Ealing-based film department made significant use of 16mm film and, during its peak, employed over 50 film crews. Throughout much of the 1960s-1990s period, these crews made use of cameras such as the Arriflex SP and Eclair NPR in combination with quarter-inch sound recorders, such as the Nagra III. Using these tools, film department crews would work on some of the most significant programmes produced by the BBC, including Man Alive , Panorama and Chronicle . Usually made up of five people, these small crews were able to work incredibly efficiently and, even in hostile environments, were able to shoot an entire programme with a filming ratio of less than 5:1. [4]

Beginning with the 1950s, news organizations and documentarians in the United States frequently shot on portable Auricon and later, CP-16 cameras that were self blimped and had the ability to record sound on film. The introduction of magnetic striped film further improved sound fidelity.

Replacing analog video devices, digital video has made significant inroads in television production use. Nevertheless, 16 mm is still in use in its Super 16 ratio (see below) for productions seeking its specific look.

Format standards

Perforations

Two perforation pitches are available for 16 mm film. One specification, known as "long pitch", has a spacing of 7.62 mm (0.300 in) and is used primarily for print and reversal film stocks. Negative and intermediate film stocks have perforations spaced 7.605 mm (0.2994 in), known as "short pitch". These differences allow for the sharpest and smoothest possible image when making prints using a contact printer.

Film stocks are available in either 'single-perf' or 'double-perf', meaning the film is perforated on either one or both edges. A perforation for 16 mm film is 1.829 mm × 1.27 mm (0.0720 in × 0.0500 in) with a radius curve on all four corners of 0.25 mm (0.0098 in). Tolerances are ±0.001 mm (4×10−5 in). [5] [6]

Standard 16 mm

The picture-taking area of standard 16 mm is 10.26 mm × 7.49 mm (0.404 in × 0.295 in), an aspect ratio of 1.37:1, the standard pre-widescreen Academy ratio for 35 mm. The "nominal" picture projection area (per SMPTE RP 20-2003) is 0.380 in by 0.284 in, [7] and the maximum picture projection area (per SMPTE ST 233-2003) is 0.384 in by 0.286 in, [8] each implying an aspect ratio of 1.34:1. Double-perf 16 mm film, the original format, has a perforation at both sides of every frame line. Single-perf is perforated at one side only, making room for an optical or magnetic soundtrack along the other side.

Super 16 mm

Super 16 and 16 mm film.

The variant called Super 16 mm, Super 16, or 16 mm Type W is an adaptation of the 1.66 aspect ratio of the "Paramount format" [9] to 16 mm film. It was developed by Swedish cinematographer Rune Ericson in 1969, [10] using single-sprocket film and taking advantage of the extra room for an expanded picture area of 12.52 mm × 7.41 mm (0.493 in × 0.292 in).

Super 16 cameras are usually 16 mm cameras that have had the film gate and ground glass in the viewfinder modified for the wider frame, and, since this process widens the frame by affecting only one side of the film, the various cameras' front mounting plate or turret areas must also be re-machined to shift and re-center the mounts for any lenses used. Because the resulting, new, Super 16 aspect-ratio takes up the space originally reserved for the 16mm soundtrack, films shot in this format must be enlarged by optical printing to 35 mm for sound-projection, and, in order to preserve the proper 1.66:1, or (slightly cropped) 1.85:1 theatrical aspect ratios which this format was designed to provide. And, with the recent development of digital intermediate workflows, it is now possible to digitally enlarge to a 35 mm sound print with virtually no quality loss (given a high quality digital scan), or alternatively to use high-quality video equipment for the original image capture.

In 2009, German lens manufacturer Vantage introduced a series of anamorphic lenses under its HAWK brand. These provided a 1.3× squeeze factor (as opposed to the standard 2×) specifically for the Super 16 format. These lenses let camera operators use the entire Super 16 frame for 2.39:1 widescreen photography.

Ultra 16 mm

The DIY-crafted Ultra 16 is a variation of Super 16. Cinematographer Frank G. DeMarco is credited with inventing Ultra 16 in 1996 while shooting tests for Darren Aronofsky's Pi. [11] Ultra 16 is created by widening the left and right sides of the gate of a standard 16 mm camera by 0.7 mm to expose part of the horizontal area between the perforations. Perforation placement on standard 16 mm film (on the one side [or, both sides, when using double-perf film] of the divisions between frames) accommodates use of these normally unexposed areas.

The Ultra 16 format, with frame dimensions of 11.66 mm × 6.15 mm (0.459 in × 0.242 in), provides a frame size between standard 16 mm and Super 16—while avoiding the expense of converting a 16 mm camera to Super 16, the larger lens-element requirements for proper aperture field coverage on Super 16 camera conversions, and, the potential image vignetting caused by trying to use some "conventional" 16 mm lenses on those Super 16 converted cameras. Thus, almost all standard 16 mm optics can now achieve the wider image in Ultra 16, but without the above pitfalls and optical "shortcomings" encountered when attempting their use for Super 16.

The image readily converts to NTSC/PAL (1.33 ratio), HDTV (1.78 ratio) and to 35 mm film (1.66 [European] and 1.85 wide screen ratios), using either the full vertical frame, or the full width (intersprocket) frame, and at times, portions of both, depending upon the required application.

Modern usage

The two major suppliers of 16 mm film in the 21st century are Kodak and Agfa (Fuji closed its film manufacturing facility on 31 December 2012). 16 mm film is used in television, such as for the Hallmark Hall of Fame anthology (it has since been produced in 16:9 high definition) and Friday Night Lights and The O.C. as well as The Walking Dead in the US. In the UK, the format is exceedingly popular for television series such as Doc Martin , dramas and commercials. The British Broadcasting Corporation (BBC) played a large part in the development of the format. It worked extensively with Kodak during the 1950s and 1960s to bring 16 mm to a professional level, since the BBC needed cheaper, more portable production solutions while maintaining a higher quality than was offered at the time, when the format was mostly for home display of theatrical shorts, newsreels, and cartoons, documentary capture and display for various purposes (including education), and limited "high end" amateur use. [12] Today[ when? ] the format also is frequently used for student films, while usage in documentary has almost disappeared. With the advent of HDTV, Super 16 film is still used for some productions destined for HD. [12] Some low-budget theatrical features are shot on 16 mm and super 16 mm such as Kevin Smith's 16 mm 1994 independent hit Clerks, or Man Bites Dog , and Mid90s .

Thanks to advances in film stock and digital technology—specifically digital intermediate (DI)—the format has dramatically improved in picture quality since the 1970s, and is now a revitalized option. Vera Drake , for example, was shot on Super 16 mm film, digitally scanned at a high resolution, edited and color graded, and then printed out onto 35 mm film via a laser film recorder. Because of the digital process, the final 35 mm print quality is good enough to fool some professionals into thinking it was shot on 35 mm.[ citation needed ]

In Britain most exterior television footage was shot on 16 mm from the 1960s until the 1990s, when the development of more portable television cameras and videotape machines led to video replacing 16 mm in many instances. Many drama shows and documentaries were made entirely on 16 mm, notably Brideshead Revisited , The Jewel in the Crown , The Ascent of Man and Life on Earth . More recently, the advent of widescreen television has led to the use of Super 16. For example, the 2008 BBC fantasy drama series Merlin was shot in Super 16. [13]

As recently as 2010, Scrubs was shot on Super16 and aired either as 4:3 SD (first 7 seasons) or as 16:9 HD (seasons 8 and 9). John Inwood, the cinematographer of the series, believed that footage from his Aaton XTR Prod camera was not only sufficient to air in high definition, it "looked terrific". [14]

The Academy Award winning Leaving Las Vegas (1995) was shot on 16 mm.

The first two seasons of Buffy the Vampire Slayer were shot on 16 mm and was switched to 35 mm for its later seasons.

The first season of the popular series Sex and the City was shot on 16 mm. Later seasons were shot on 35 mm. All three seasons of Veronica Mars were shot on 16 mm and aired in HD. This Is Spinal Tap , and Christopher Guest's subsequent mockumentary films, are shot in Super 16 mm.

The first three seasons of Stargate SG-1 (bar the season 3 finale and the effects shots) were shot in 16 mm, before switching to 35 mm for later seasons.

The 2009 Academy Award winner for Best Picture, The Hurt Locker , was shot using Aaton Super 16 mm cameras and Fujifilm 16 mm film stocks. The cost savings over 35 mm allowed the production to utilize multiple cameras for many shots, exposing over 1,000,000 feet of film. [15]

British Napoleonic era TV drama Sharpe was shot on Super 16 mm right through to the film Sharpe's Challenge (2006). For the last film in the series, Sharpe's Peril (2008), the producers switched to 35 mm.

Moonrise Kingdom was shot using super 16 mm.

Darren Aronofsky shot mother! on 16 mm. [16]

Linus Sandgren shot most of the 2018 biographical drama First Man on Super 16. [17]

Spike Lee shot the Netflix film Da 5 Bloods ' flashback scenes on 16 mm film. This is part of the reason cinematographer Newton Thomas Sigel is an Oscar contender for his work on the film. The Insider reports that Netflix "was initially concerned about having the movie's flashback scenes shot on grainy 16 mm film ... There was pushback because it opened up a lot of challenges." According to Sigel, the film stock Lee wanted to use was an expensive one as it is rarely used today. It would be even more expensive to shoot on 16mm film while on location in Vietnam and then ship the film back to the United States to be processed at a film lab. Lee was "pretty adamant" about using 16mm for the flashbacks; Sigel said "I would never have been able to do it without such fervent support from him." Sigel pitched to Lee an idea to shoot the Vietnam sequences using the kind of camera and film stock that would have been available during the Vietnam era. [18]

Digital 16 mm

A number of digital cameras approximate the look of the 16 mm format by using 16 mm-sized sensors and taking 16 mm lenses. These cameras include the Ikonoskop A-Cam DII (2008) and the Digital Bolex (2012). The Blackmagic Pocket Cinema Camera (2013) and the Blackmagic Micro Cinema Camera (2015) has a Super 16-sized sensor. The Z CAM E2G (2019) even offers Digital 16 mm in 4K and with a global shutter.

The professional industry tends to use 16 mm cameras from Aaton and Arri, most notably the Aaton Xtera, Aaton XTRprod, Arriflex 16SR3, and Arriflex 416. Aaton also released the A-Minima, which is about the size of a video camcorder and is used for specialized filming requiring smaller, more versatile cameras. Photo Sonics have special extremely high speed cameras for 16 mm that film at up to 1,000 frames per second. Panavision has produced the Panaflex 16, nicknamed "Elaine".

Amateur cameras

For amateur, hobbyist, and student use, it is more economical to use older models from Arri, Aaton, Auricon, Beaulieu, Bell and Howell, Bolex, Canon, Cinema Products, Eclair, Keystone, Krasnogorsk, Mitchell, and others.

Film reproduction methods

Most original movie production companies that use film shoot on 35 mm. The 35 mm size must be converted or reduced to 16 mm for 16 mm systems. There are multiple ways of obtaining a 16 mm print from 35 mm. The preferred method is to strike a 16 mm negative from the original 35 mm negative and then make a print from the new 16 mm negative. A 16 mm negative struck from the original 35 mm negative is called an original. A new 16 mm print made from a print with no negative is called a reversal. 16 mm prints can be made from many combinations of size and format, each with a distinct, descriptive name:

Film traders often refer to 16 mm prints by the print's production method, i.e., an original, reversal, dupe down, double dupe, or double dupe down.

Color fading of old film and color recovery

Over time, the cyan, magenta and yellow dyes that form the image in color 16 mm film inevitably fade. The rate of deterioration depends on storage conditions and the film type. In the case of Kodachrome amateur and documentary films and Technicolor IB (imbibition process) color prints, the dyes are so stable and the deterioration so slow that even prints now over 70 years old typically show no obvious problems.

Unfortunately, dyes in the far more common Eastmancolor print film and similar products from other manufacturers are notoriously unstable. Prior to the introduction of a longer-lasting "low fade" type in 1979, Eastmancolor prints routinely suffered from easily seen color shift and fading within ten years. The dyes degrade at different rates, with magenta being the longest-lasting, eventually resulting in a pale reddish image with little if any other color discernible. [19]

In the process of digitizing old color films, even badly faded source material can sometimes be restored to full color through digital techniques that amplify the faded dye colors.

Widescreen Aspect ratio of a displayed image

Widescreen images are images that are displayed within a set of aspect ratios used in film, television and computer screens. In film, a widescreen film is any film image with a width-to-height aspect ratio greater than the standard 1.37:1 Academy aspect ratio provided by 35 mm film.

35 mm movie film Motion picture film gauge, the standard

35 mm film is a film gauge used in filmmaking, and the film standard. 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. The standard image exposure length on 35 mm for movies is four perforations per frame along both edges, which results in 16 frames per foot of film.

VistaVision Motion picture camera film format

VistaVision is a higher resolution, widescreen variant of the 35 mm motion picture film format which was created by engineers at Paramount Pictures in 1954.

70 mm film

70 mm film is a wide high-resolution film gauge for motion picture photography, with negative area nearly 3.5 times as large as the standard 35 mm motion picture film format. As used in cameras, the film is 65 mm (2.6 in) wide. For projection, the original 65 mm film is printed on 70 mm (2.8 in) film. The additional 5 mm are for four magnetic strips holding six tracks of stereophonic sound. Although later 70 mm prints use digital sound encoding, the vast majority of existing and surviving 70 mm prints pre-date this technology.

8 mm film

8 mm film is a motion picture film format in which the film strip is eight millimeters wide. It exists in two main versions – the original standard 8 mm film, also known as regular 8 mm, and Super 8. Although both standard 8 mm and Super 8 are 8 mm wide, Super 8 has a larger image area because of its smaller and more widely spaced perforations.

Super 8 film Small film format by Kodak

Super 8mm film is a motion picture film format released in 1965 by Eastman Kodak as an improvement over the older "Double" or "Regular" 8 mm home movie format.

A movie camera, film camera or cine-camera is a type of photographic camera which takes a rapid sequence of photographs on an image sensor or on a film. 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. While viewing at a particular frame rate, a person's eyes and brain merge the separate pictures to create the illusion of motion.

CinemaScope Early widescreen filming system

CinemaScope is an anamorphic lens series used, from 1953 to 1967, and less often later, for shooting widescreen films that, crucially, could be screened in theatres using existing equipment, albeit with a lens adapter. Its creation in 1953 by Spyros P. Skouras, the president of 20th Century Fox, marked the beginning of the modern anamorphic format in both principal 2.55:1, almost twice as wide as the previously common Academy format's 1.37:1 ratio. Although the technology behind the CinemaScope lens system was made obsolete by later developments, primarily advanced by Panavision, CinemaScope's anamorphic format has continued to this day. In film-industry jargon, the shortened form, 'Scope, is still widely used by both filmmakers and projectionists, although today it generally refers to any 2.35:1, 2.39:1, 2.40:1, or 2.55:1 presentation or, sometimes, the use of anamorphic lensing or projection in general. Bausch & Lomb won a 1954 Oscar for its development of the CinemaScope lens.

Negative pulldown is the manner in which an image is exposed on a film stock, described in the number of film perforations spanned by an individual frame. It can also describe the orientation of the image on the negative, whether it is captured horizontally or vertically. Changing the number of exposed perforations allows a cinematographer to change both the aspect ratio of the image and the size of the area on the film stock that the image occupies.

Techniscope Motion picture camera film format

Techniscope or 2-perf is a 35 mm motion picture camera film format introduced by Technicolor Italia in 1960. The Techniscope format uses a two film-perforation negative pulldown per frame, instead of the standard four-perforation frame usually exposed in 35 mm film photography. Techniscope's 2.33:1 aspect ratio is easily cropped to the 2.39:1 widescreen ratio, because it uses half the amount of 35 mm film stock and standard spherical lenses. Thus, Techniscope release prints are made by anamorphosizing and enlarging each frame by a factor of two.

Super 35 is a motion picture film format that uses exactly the same film stock as standard 35 mm film, but puts a larger image frame on that stock by using the space normally reserved for the optical analog sound track.

Technirama

Technirama is a screen process that has been used by some film production houses as an alternative to CinemaScope. It was first used in 1957 but fell into disuse in the mid-1960s. The process was invented by Technicolor and is an anamorphic process with a screen ratio the same as revised CinemaScope (2.35:1), but it is actually 2.25:1 on the negative.

Univisium

Univisium is a proposed universal film format created by cinematographer Vittorio Storaro, ASC, AIC and his son, Fabrizio, to unify all future theatrical and television films into one respective aspect ratio of 2:1 (18:9).

Academy ratio Aspect ratio with a width of 1.37 units and height of 1

The Academy ratio of 1.375:1 is an aspect ratio of a frame of 35 mm film when used with 4-perf pulldown. It was standardized by the Academy of Motion Picture Arts and Sciences as the standard film aspect ratio in 1932, although similar-sized ratios were used as early as 1928.

Film perforations

Film perforations, also known as perfs and sprocket holes, are the holes placed in the film stock during manufacturing and used for transporting and steadying the film. Films may have different types of perforations depending on film gauge, film format, and intended usage. Perforations are also used as a standard measuring reference within certain camera systems to refer to the size of the frame.

Ultra Panavision 70

Ultra Panavision 70 and MGM Camera 65 were, from 1957 to 1966, the marketing brands that identified motion pictures photographed with Panavision's anamorphic movie camera lenses on 65 mm film. Ultra Panavision 70 and MGM Camera 65 were shot at 24 frames per second (fps) using anamorphic camera lenses. Ultra Panavision 70 and MGM Camera 65's anamorphic lenses compressed the image 1.25 times, yielding an extremely wide aspect ratio of 2.76:1.

Anamorphic format Technique for recording widescreen images onto a 4:3 frame

Anamorphic format is the cinematography technique of shooting a widescreen picture on standard 35 mm film or other visual recording media with a non-widescreen native aspect ratio. It also refers to the projection format in which a distorted image is "stretched" by an anamorphic projection lens to recreate the original aspect ratio on the viewing screen. The word anamorphic and its derivatives stem from the Greek anamorphoun, compound of morphé with the prefix aná. In the late 1990s and 2000s, anamorphic lost popularity in comparison to "flat" formats such as Super 35 with the advent of digital intermediates; however in the years since digital cinema cameras and projectors have become commonplace, anamorphic has experienced a considerable resurgence of popularity, due in large part to the higher base ISO sensitivity of digital sensors, which facilitates shooting at smaller apertures.

The aspect ratio of an image is the ratio of its width to its height. It is commonly expressed as two numbers separated by a colon, as in 16:9. For an x:y aspect ratio, the image is x units wide and y units high. Widely used aspect ratios include 1.85:1 and 2.39:1 in film photography, 4:3 and 16:9 in television, and 3:2 in still camera photography.

Test film

Test film are rolls or loops or slides of photographic film used for testing the quality of equipment. Equipment to be tested could include: telecine, motion picture film scanner, Movie projectors, Image scanners, film-out gear, Film recorders and Film scanners.
