The IMAX Camera
The IMAX camera is designed to shoot the 15/70 film format. The IMAX camera uses 65mm negative film stock which is later contact printed to 70mm print stock (positive) for projection. The image area on the negative and on the print film stock is the same—the additional area on the 70mm format was originally designed to accommodate a soundtrack (optically or magnetically encoded).

IMAX cameras weigh between 42 and 100 pounds (19-45 Kg) approximately, depending on model and configuration. 3D film camera configurations weigh significantly more. A typical film load (one roll) is 1,000 feet (305 metres) in length and representsapproximately 3 minutes of raw footage.

Alternate Formats
Other camera systems are sometimes used by filmmakers to capture scenes for use in films that will be exhibited on giant screens. These camera systems include 35mm and HD video. Typically scenes acquired on these lower resolution systems are digitally remastered to enhance their appearance for the big screen. IMAX Corporation offers a proprietary digital remastering service entitled DMR which is used principally to repurpose 35mm feature films for release in IMAX cinemas. Alternative formats cannot offer the full resolution and clarity possible with 15/70 film, but they do provide ways to create content that is not necessarily feasible with the larger and more expensive 15/70 format.
