IMAX
IMAX (an acronym for Image MAXimum) is a motion picture film format and a set of cinema projection standards created by Canadian company IMAX Corporation and developed 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 October 1, 2015, there were 1008 IMAX theatres in 66 countries.
History
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.
