There are two different meanings for the term reduction print. In cinema it is a film print reduced in size, typically for showing in smaller cinemas. In printmaking it is a (rather uncommon) form of colour printing by working the same block (so "reducing" it) in a series of print runs, each just printing one colour.
A reduction print is a print of a large-size format film converted to a smaller size format (for example, a 70mm print converted to 35mm). Often this is necessary because not all theatres have a screen of the size required to show a film in large format, or indeed the projection equipment. [1] This is especially true of some screens in multiplex theatres. In former days, it was true of the neighbourhood theatres located outside of downtown areas.
Conversely, a "blow-up print" is a regular format film converted to larger size (i.e., 35mm to 70mm). This was once often done so that "regular-sized" film would seem even more impressive on screens such as the ones in Cinerama theatres. [2]
In woodcut and other forms of relief printing, a reduction print is a multicolour print in which the separate colours are printed from the same block at different stages. Usually, the lightest colour of the design is printed first, then the block is "reduced" by carving to the areas which the artist wants to print the second colour from, and so forth. The disadvantage of reduction printing as opposed to printing from multiple blocks is that once the first colour is printed, the matrix for it is destroyed in the creation of the printing matrix for the second colour. It is impossible to undo mistakes. [3]
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).
Screen printing is a printing technique where a mesh is used to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil. A blade or squeegee is moved across the screen to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact. This causes the ink to wet the substrate and be pulled out of the mesh apertures as the screen springs back after the blade has passed. One colour is printed at a time, so several screens can be used to produce a multi-coloured image or design.
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 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.
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.
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.
5.1 surround sound is the common name for surround sound audio systems. 5.1 is the most commonly used layout in home theatres. It uses five full bandwidth channels and one low-frequency effects channel. Dolby Digital, Dolby Pro Logic II, DTS, SDDS, and THX are all common 5.1 systems. 5.1 is also the standard surround sound audio component of digital broadcast and music.
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.
A contact print is a photographic image produced from film; sometimes from a film negative, and sometimes from a film positive or paper negative. In a darkroom an exposed and developed piece of film or photographic paper is placed emulsion side down, in contact with a piece of photographic paper, light is briefly shone through the negative or paper and then the paper is developed to reveal the final print.
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.
Dolby Stereo is a sound format made by Dolby Laboratories. It is a unified brand for two completely different basic systems: the Dolby SVA 1976 system used with optical sound tracks on 35mm film, and Dolby Stereo 70mm noise reduction on 6-channel magnetic soundtracks on 70mm prints.
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.
Microforms are scaled-down reproductions of documents, typically either films or paper, made for the purposes of transmission, storage, reading, and printing. Microform images are commonly reduced to about 4% or 1⁄25 of the original document size. For special purposes, greater optical reductions may be used.
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.
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.
Dye transfer is a continuous-tone color photographic printing process. It was used to print Technicolor films, as well as to produce paper colour prints used in advertising, or large transparencies for display.
Technicolor is a series of color motion picture processes, the first version dating back to 1916, and followed by improved versions over several decades.
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.
