IMAX is a motion picture film format that consists of a system of high-resolution cameras, film formats, film projectors, and film theaters. It was developed in Canada in the 1970s to give viewers an immersive movie-watching experience with its large screens. IMAX theater screens have a tall aspect ratio of 1.43:1 or 1.9:1, and the screens can be as large as 18 by 24 meters, with the largest screen in Leonberg, Germany, measuring 38.8 meters by 21 meters. The key features of IMAX technology include:

• Large screens: IMAX screens are much larger than those in traditional theaters, providing a more immersive experience.

• High-resolution cameras: IMAX cameras are known industry-wide as the best premium filmmaking tools available today.

• Patented digital audio technology: IMAX theaters feature a patented digital audio technology with advanced circuits designed specifically to enhance sound clarity and depth of sound reproduction.

• Film format: IMAX technology uses the largest commercial film format in motion picture history -- 70mm, 15-perforation -- three times the size of regular 70mm, and ten times the size of conventional 35mm which you would see in a normal movie theater.

• DMR process: IMAXs remastering process, or DMR, fully transforms every frame of a film to produce the best possible version of a filmmakers vision.

IMAX has consistently reported gross annual profits above $100 million, and it has been partnering with local studios and producers to promote the use of IMAX cameras for big-budget films.
