IMAX Dome (OMNIMAX) is identical to IMAX, but photographed with an extremely wide-angle lens, and projected onto a concave dome screen up to 30 meters in diameter, instead of a flat one. The IMAX DOME cinemas are physically very different to IMAX cinemas, but in practice, the two formats are largely interchangeable. IMAX DOME prints play IMAX theatres, and IMAX prints, with or without optical conversion for the concave, play IMAX DOME theatres.
