Imax theater giant screen

IMAX theaters revolutionized the cinematic experience with giant screens and high-definition projection technology.

About this subject

The IMAX (Image Maximum) system was developed in Canada in 1967 by Graeme Ferguson, Roman Kroitor, and Robert Kerr, with its first public exhibition at Expo 67 in Montreal. The technology is distinguished by screens that can reach up to 22 meters wide by 16 meters high, combined with 70 mm horizontal-roll projectors, offering superior resolution and brightness compared to conventional cinema. The standard aspect ratio is 1.43:1, filling the viewer's entire field of vision.

IMAX theaters are designed for maximum immersion: seats are reclined and positioned close to the screen, and the proprietary sound system uses independent channels with high-power speakers. Variations include the IMAX Dome (OMNIMAX), with a hemispherical screen used in planetariums, and IMAX Digital, which uses two 4K projectors for multiplex cinemas. Today, over 1,700 IMAX theaters operate in more than 80 countries.

Culturally, IMAX has become synonymous with action and science fiction blockbusters, with directors like Christopher Nolan shooting specific scenes for the format. Beyond commercial films, it is widely used in educational documentaries about nature and science, such as those from NASA and National Geographic. The format also hosts live events, including concerts and sports broadcasts, due to its audiovisual quality.

Technologically, evolution continues with IMAX with Laser, offering better contrast and colors, and IMAX 3D, using polarized glasses for stereoscopic effect. The trend for 2026 includes expanding IMAX into virtual reality experiences and home theaters, maintaining its leadership in cinematic innovation.
