IMAX is a motion picture film format and a set of cinema projection standards created by the 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 into IMAX format for display 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 31 December 2013, there are 837 IMAX theatres in 57 countries.
