IMAX
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 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, 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 18 by 24 metres 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.
