OmniMax
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 (approximately either 1.43:1 or 1.90:1) and steep stadium seating. Graeme Ferguson, Roman Kroitor, Robert Kerr, and William C. Shaw were the co-founders of what would be named the IMAX Corporation (founded in September 1967 as Multiscreen Corporation, Limited), and they developed the first IMAX cinema projection standards in the late 1960s and early 1970s in Canada. IMAX GT is the large format as originally conceived. It uses very large screens of and, unlike most conventional film projectors, the film runs horizontally so that the image width can be greater than the width of the film stock. It is called a 70/15 format. It is used exclusively in purpose-built theaters and dome theaters, and many installations limit themselves to a projection of high quality, short documentaries. The high costs involved in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

70 mm Film
70 mm film (or 65 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 wide. For projection, the original 65 mm film is printed on 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 (specifically the DTS format), the vast majority of existing and surviving 70 mm prints pre-date this technology. Each frame is five perforations tall, with an aspect ratio of 2.2:1. However, the use of anamorphic Ultra Panavision 70 lenses squeezes the image into an ultra-wide 2.76:1 aspect ratio. To this day, Ultra Panavision 70 produces the widest picture size in the history of filmmaking; surpassed only by Polyvision, which was only used for 1927's Napoleon. With regard to exhibition, 70 mm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fulldome
Fulldome refers to immersive dome-based video display environments. The dome, horizontal or tilted, is filled with real-time (interactive) or pre-rendered (linear) computer animations, live capture images, or composited environments. Although the current technology emerged in the early-to-mid 1990s, fulldome environments have evolved from numerous influences, including immersive art and storytelling, with technological roots in domed architecture, planetariums, multi-projector film environments, flight simulation, and virtual reality. Initial approaches to moving fulldome imagery used wide-angle lenses, both 35 and 70 mm film, but the expense and ungainly nature of the film medium prevented much progress; furthermore, film formats such as Omnimax did not cover the full two pi steradians of the dome surface, leaving a section of the dome blank (though, due to seating arrangements, that part of the dome was not seen by most viewers). Later approaches to fulldome utilized monoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LEAD
Lead is a chemical element with the Symbol (chemistry), symbol Pb (from the Latin ) and atomic number 82. It is a heavy metals, heavy metal that is density, denser than most common materials. Lead is Mohs scale of mineral hardness#Intermediate hardness, soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable nuclide, stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and base (chemistry), bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cinerama
Cinerama is a widescreen process that originally projected images simultaneously from three synchronized 35mm projectors onto a huge, deeply curved screen, subtending 146° of arc. The trademarked process was marketed by the Cinerama corporation. It was the first of a number of 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 projection screen, rather than being a continuous surface like most screens, is made of hundreds of individual vertical strips of standard perforated screen material, each about inch (~22 mm) wide, with each strip angled to face the audience, so as to prevent light scattered from one end of the deeply curved screen from reflecting across the screen and washing out the image on the opposite end ...

VistaVision
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. Paramount never used anamorphic processes such as 2.55: 1, CinemaScope but refined the quality of its flat widescreen system by orienting the 35 mm negative horizontally in the camera gate and shooting onto a big area, which yielded the finer-grained projection print. As finer-grained film stocks appeared on the market, VistaVision became obsolete. Paramount dropped the format just after seven years, although for 40 more years the format was used by some European and Japanese producers for movies, and by USA movies such as the first three ''Star Wars'' films for high-resolution special effects sequences. In many ways, VistaVision became the testing ground for every cinematography idea that evolved into 70 mm IMAX and OMNIMAX film formats in the 1970s. Both IMAX and OMNIMAX are oriented sideways, like Vist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Movie Projector
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. (see also digital cinema) Many projectors are specific to a particular film gauge and not all movie projectors are film projectors since the use of film is required. Predecessors The main precursor to the movie projector was the magic lantern. In its most common setup it had a concave mirror behind a light source to help direct as much light as possible through a painted glass picture slide and a lens, out of the lantern onto a screen. Simple mechanics to have the painted images moving were probably implemented since Christiaan Huygens introduced the apparatus around 1659. Initially candles and oil lamps were used, but other light sources, such as the argand lamp and limelig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Film Board Of Canada
The National Film Board of Canada (NFB; french: Office national du film du Canada (ONF)) is Canada's public film and digital media producer and distributor. An agency of the Government of Canada, the NFB produces and distributes documentary films, animation, web documentaries, and alternative dramas. In total, the NFB has produced over 13,000 productions since its inception, which have won over 5,000 awards. The NFB reports to the Parliament of Canada through the Minister of Canadian Heritage. It has bilingual production programs and branches in English and French, including multicultural-related documentaries. History Canadian Government Motion Picture Bureau The Exhibits and Publicity Bureau was founded on 19 September 1918, and was reorganized into the Canadian Government Motion Picture Bureau in 1923. The organization's budget stagnated and declined during the Great Depression. Frank Badgley, who served as the bureau's director from 1927 to 1941, stated that the bu ...

Expo 67
The 1967 International and Universal Exposition, commonly known as Expo 67, was a general exhibition from April 27 to October 29, 1967. It was a category One World's Fair held in Montreal, Quebec, Canada. It is considered to be one of the most successful World's Fairs of the 20th century with the most attendees to that date and 62 nations participating. It also set the single-day attendance record for a world's fair, with 569,500 visitors on its third day. Expo 67 was Canada's main celebration during its centennial year. The fair had been intended to be held in Moscow, to help the Soviet Union celebrate the Russian Revolution's 50th anniversary; however, for various reasons, the Soviets decided to cancel, and Canada was awarded it in late 1962. The project was not well supported in Canada at first. It took the determination of Montreal's mayor, Jean Drapeau, and a new team of managers to guide it past political, physical and temporal hurdles. Defying a computer analysis that sa ...

70 mm Grandeur Film
70mm Grandeur film, also called Fox Grandeur or Grandeur 70, is a 70mm widescreen film format developed by William Fox through his Fox Film and Fox-Case corporations and used commercially on a small but successful scale in 1929–30. Filmography In 1925, with the advent of television on the horizon, William Fox of the Fox Film Studio empire envisioned a "grand" cinema experience to keep the public coming to the movie theaters. As such, he soon put full efforts behind enhancing the silent 35mm film showings by the addition of sound to be coupled to a wider than 35mm end product, with the hoped for result being a grand and lifelike experience for the viewers. This wide screen vision of William Fox soon resulted in his creating a partnership with Theodore Case and his assistant, Earl Sponable, pioneers of Sound on Film, with the partnership to be named the Fox-Case Corporation. The result was, first, the advent of Movietone Sound, then soon combined with the 70mm "Grandeur" wide scree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In The Labyrinth (film)
''In the Labyrinth'' ''(French: Dans le labyrinthe)'' was a groundbreaking multi-screen presentation at the Labyrinth pavilion at Expo 67 in Montreal, Quebec, Canada. It used 35 mm and 70 mm film projected simultaneously on multiple screens and was the precursor of today's IMAX format. History Roman Kroitor created a six-screen exhibit to show National Film Board of Canada at the Canadian National Exhibition in 1963. He later proposed creating a screen that had a display with the maximum horizontal and vertical fields of vision, but was unable to gain financial backing until the NFB got a spot at He later proposed a Expo 67. He created ''Faces'' to show how his idea would work and it utilized two screens. Kroitor, Low, and Hugh O'Connor started working on the project in January 1964, with Tom Daly executive producing. Northrop Frye was brought in to aid in planning the scenario and suggested seven psychological steps of initiation (origins, childhood, confident, youth, the ...
