Widescreen images 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 4:3 (12:9).
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.
70 mm film is a wide high-resolution film gauge for motion picture photography, with a 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 contains the four magnetic stripes, 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.
IMAX is a proprietary system of high-resolution cameras, film formats, film projectors, and theaters known for having very large screens with a tall aspect ratio and steep stadium seating, with the 1.43:1 ratio format being available only in few selected locations.
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.
Cinerama is a widescreen process that originally projected images simultaneously from three synchronized 35mm projectors onto a huge, deeply curved screen, subtending 146-degrees of arc. The trademarked process was marketed by the Cinerama corporation. It was the first of several novel processes introduced during the 1950s when the movie industry was reacting to competition from television. Cinerama was presented to the public as a theatrical event, with reserved seating and printed programs, and audience members often dressed in their best attire for the evening.
The Cinerama Dome is a movie theater located at 6360 Sunset Boulevard in Hollywood, California. Designed to exhibit widescreen Cinerama films, it opened November 7, 1963. The original developer was William R. Forman, founder of Pacific Theatres. The Cinerama Dome continued as a leading first-run theater, most recently as part of the ArcLight Hollywood complex, until it closed temporarily in March 2020, due to the COVID-19 pandemic in California. The ArcLight chain closed permanently in April 2021, with the theater never having reopened. In June 2022, it was announced that there are plans to reopen it and the former ArcLight Hollywood under a new name, Cinerama Hollywood.
A movie projector is an opto-mechanical device for displaying motion picture film by projecting it onto a screen. Most of the optical and mechanical elements, except for the illumination and sound devices, are present in movie cameras. Modern movie projectors are specially built video projectors.
Negative pulldown is the manner in which an image is exposed on a film stock, described by the number of film perforations spanned by an individual frame. It can also describe whether the image captured on the negative is oriented 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.
Todd-AO is an American post-production company founded in 1953 by Mike Todd and Robert Naify, providing sound-related services to the motion picture and television industries. For more than five decades, it was the worldwide leader in theater sound. The company now operates one facility in the Los Angeles area.
A roadshow theatrical release or reserved seat engagement is the practice of opening a film in a limited number of theaters in major cities for a specific period of time before the wide release of the film. Roadshows would generally mimic a live theatre production, with an upscale atmosphere as well as somewhat higher prices than during a wide release. They were commonly used to promote major films from the 1920s–60s and build excitement.
Panavision is an American motion picture equipment company founded in 1953 specializing in cameras and lenses, based in Woodland Hills, California. Formed by Robert Gottschalk as a small partnership to create anamorphic projection lenses during the widescreen boom in the 1950s, Panavision expanded its product lines to meet the demands of modern filmmakers. The company introduced its first products in 1954. Originally a provider of CinemaScope accessories, the company's line of anamorphic widescreen lenses soon became the industry leader. In 1972, Panavision helped revolutionize filmmaking with the lightweight Panaflex 35 mm movie camera. The company has introduced other cameras such as the Millennium XL (1999) and the digital video Genesis (2004).
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 enlarged 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 anamorphosing, enlarging each frame vertically by a factor of two.
Super Panavision 70 is the marketing brand name used to identify movies photographed with Panavision 70 mm spherical optics between 1959 and 1983.
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 anamorphoo, 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.
Panavision has been a manufacturer of cameras for the motion picture industry since the 1950s, beginning with anamorphic widescreen lenses. The lightweight Panaflex is credited with revolutionizing filmmaking. Other influential cameras include the Millennium XL and the digital video Genesis.
The aspect ratio of an image is the ratio of its width to its height, and is expressed with two numbers separated by a colon, such as 16:9, sixteen-to-nine. For the x:y aspect ratio, the image is x units wide and y units high. Common aspect ratios are 1.85:1 and 2.39:1 in cinematography, 4:3 and 16:9 in television photography, and 3:2 in still photography.
The Hateful Eight is a 2015 American Western mystery thriller film written and directed by Quentin Tarantino. It stars Samuel L. Jackson, Kurt Russell, Jennifer Jason Leigh, Walton Goggins, Demián Bichir, Tim Roth, Michael Madsen and Bruce Dern, as eight strangers who seek refuge from a blizzard in a stagecoach stopover some time after the American Civil War.
