IMAX® Film Making
The IMAX® image... is the largest in motion picture history. The facts are simple:
To create a high quality image, the bigger the screen size, the larger the film
frame needs to be. Film frames are measured by perforations and millimeters.
A smaller screen "only" four stories high can project a high quality image with film
that has eight perforations and is 70 millimeters wide. For a eight-story screen,
1570 film is required. 1570 film--the standard IMAX format--is ten times the size
of a conventional 35mm frame and three times larger than a normal 70mm movie
frame. The sheer size of IMAX-format frames, combined with the unique projection
technology, is the key to the extraordinary sharpness and clarity of IMAX films.
The IMAX® camera...versatile and dependable, and an integral part
of the system. They've endured everything from the heat and thrust of a space shuttle launch to use under water and constant engineering
adaptations are required to take the cameras on the demanding adventures displayed in large-format films.
The IMAX® projector...the most advanced, most precise, most powerful projector
ever built. IMAX projectors rely on unique movements such as the "Rolling
Loop" to provide superior performance and reliability. The Rolling Loop advances the
film horizontally through the projector in a smooth, wave-like motion; during projection, each frame is positioned on fixed registration pins, and the film is help firmly against
the rear element of the lens by a vacuum.
