Omnimax

Omnimax expands on the classic IMAX format—the screen envelops the viewer in a dome or hemisphere, creating a field of view of approximately 180 degrees. This isn't just a larger screen; it's a completely different cinematic experience. Anyone sitting in such a theater for the first time immediately notices: the image surrounds you. There are no more edges to the frame, only ambiance and space.

The camera side is significantly more demanding than with standard IMAX. You need specially calibrated IMAX-certified cameras—not all large-format productions work for Omnimax projection. The footage is shot on 65mm (or digitally in native UHD/4K resolution), and the optical calculations for spherical projection require precise geometric adjustments. If calculated incorrectly, the perspective can quickly appear distorted or cause nausea. You can't just improvise focal lengths here—every angle, every lens must be calculated before projection.

In practice, this means Omnimax is used for highly specific content. Nature films benefit enormously from it—a flight over the Grand Canyon completely envelops the viewer. But documentaries and science center productions also rely on it. Narrative feature films are rarer because the storytelling can suffer from the extreme spatial effect; dialogue-heavy material often feels overwhelming rather than intimate.

Planetarium productions and Fulldome formats are technically similar, but Omnimax remains the established cinema format with a genuine theater chain. The costs are considerable—not only camera technology and special optics, but also licensing fees to IMAX and the limited number of Omnimax theaters worldwide make such productions major undertakings. You don't do this on the side. But when the story requires spatial immersion—when the image itself becomes the space of action—there is no comparable format.
