IMAX 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. IMAX has the capacity to record and display images of far greater size, since 2002, some feature films have been converted 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 impact of film has a long history. In 1929, Fox introduced Fox Grandeur, the first 70 mm film format, in the 1950s, the potential of 35 mm film to provide wider projected images was explored in the processes of CinemaScope and VistaVision, following multi-projector systems such as Cinerama. While impressive, Cinerama was difficult to install, during Expo 67 in Montreal, the National Film Board of Canadas In the Labyrinth and Fergusons Man and the Polar Regions both used multi-projector, multi-screen systems. Each encountered technical difficulties led them to found a company called Multiscreen. As it became clear that a single, large-screen image had more impact than multiple smaller ones and was a viable product direction. 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, tiger Child, the first IMAX film, was demonstrated at Expo 70 in Osaka, Japan. The first permanent IMAX installation was built at the Cinesphere theatre at Ontario Place in Toronto and it debuted in May 1971, showing the film North of Superior. The installation is still in place, however, Ontario Place is on hiatus for redevelopment, during Expo 74 in Spokane, Washington, an IMAX screen that measured 27 m ×20 m was featured in the US Pavilion. It became the first IMAX Theatre to not be partnered with any brand of movie theaters. About five million visitors viewed the screen, which covered the total visual field when looking directly forward. This created a sensation of motion in most viewers, and motion sickness in some, much to the dismay of the majority of Spokane and the disapproval of the IMAX Corporation itself, it will be demolished to make way for a parking lot. Another IMAX 3D theater was built in Spokane, not too far from where the original was. However, its screen-size is less than half that of the original, due to protests, the IMAX Corporation has been able to remodel the area with the city, and turn the U. S. Pavilion itself into the first permanent outdoor IMAX screen, the first permanent IMAX Dome installation, the Eugene Heikoff and Marilyn Jacobs Heikoff Dome Theatre at the Reuben H. Fleet Science Center, opened in San Diegos Balboa Park in 1973, the first permanent IMAX 3D theatre was built in Vancouver, British Columbia for Transitions at Expo 86, and was in use until September 30,2009
