The technical term for the proportional relationship between an image’s width and its height is called aspect ratio. Most films today are presented in an aspect ratio called CinemaScope (2.40:1); it was the newest thing in movie making in 1953 – and it’s still the standard today. When a film is presented in CinemaScope it is cropped and uses only part of the image the movie camera captures. This is the reason most ordinary screens are very wide but not particularly high – like looking at the world through a narrow slit.
IMAX broke the mold. We provide filmmakers with the ability to expand their film’s aspect ratio for an IMAX presentation so they can utilize much more of the originally captured image - either during production through shooting with the extremely high-resolution IMAX® camera (capable of up to IMAX® 1.43:1), which offers IMAX moviegoers up to 40% more of the image than standard cinemas, or protecting more of the image during their post production process (capable of up to IMAX® 1.9:1), which offers IMAX moviegoers up to 21% more of the image than standard cinemas.
And when this image is projected onto an IMAX® screen, which isn’t simply larger; but also curved, taller for its width and positioned closer to the audience than ordinary screens, the result provides you with a full panoramic view that fills your peripheral vision more than any other cinematic experience. That’s why, when you watch an IMAX movie, it feels like it’s all around you.
IMAX’s aspect ratio is just one of the reasons The IMAX Experience® is so different – why you feel like you’re inside the action, not just watching it.
