IMAX Theater


IMAX (an acronym for Image maximum) is a motion picture film format and a set of cinema projection standards developed in Canada by Graeme Ferguson, Roman Kroitor, Robert Kerr, and William C. Shaw. IMAX has the capacity to record and display images of far greater size and resolution than conventional film systems. Since 2002, some feature films have been converted (or upgraded) into IMAX format for displaying in IMAX theatres and some have also been partially shot in IMAX.

IMAX is the most widely used system for special-venue film presentations. As of June 2016, there were 1,102 IMAX theatres in 69 countries.

The desire to increase the visual impact of film has a long history. In 1929, Fox introduced Fox Grandeur, the first 70 mm film format, but it quickly fell from use. In the 1950s, the potential of 35 mm film to provide wider projected images was explored in the processes of CinemaScope (1953) and VistaVision (1954), following multi-projector systems such as Cinerama (1952). While impressive, Cinerama was difficult to install.

During Expo 67 in Montreal, the National Film Board of Canada's In the Labyrinth and Ferguson's Man and the Polar Regions both used multi-projector, multi-screen systems. Each encountered technical difficulties that led them to found a company called "Multiscreen", with a goal of developing a simpler approach. The single-projector/single-camera system they eventually settled upon was designed and built by Shaw based upon a novel "Rolling Loop" film-transport technology purchased from Peter Ronald Wright Jones, a machine shop worker from Brisbane, Australia (see U.S. Patent 3,494,524). As it became clear that a single, large-screen image had more impact than multiple smaller ones and was a more viable product direction, Multiscreen changed its name to IMAX. An IMAX 3D theatre also is in operation near the former Expo 67 site at the Montreal Science Centre in the Port of Old Montreal.
