“Shot with IMAX” refers specifically to films captured using IMAX’s large-format 15-perf 65mm film cameras, while “Filmed for IMAX” describes a wider production programme designed for IMAX presentation. The terms can overlap, as with Christopher Nolan’s The Odyssey, but a film can be made for IMAX using approved digital cameras rather than IMAX film cameras.

IMAX film produces the tall 1.43:1 image, though only selected cinemas can project IMAX 70mm prints; films such as Oppenheimer used the format for only some sequences. The “Filmed for IMAX” programme involves planning aspect ratios and post-production for IMAX screens, with certified cameras from makers including ARRI, Panavision, RED and Sony. Dune used certified digital cameras and expanded to 1.43:1 in selected venues, while other releases may remain at 1.90:1 or expand only for certain scenes.
