Trio of competitors offer alternatives to digital

The chase for 3D dollars has had an unexpected side effect: the revival of 3D on 35mm film.

TECHNICOLOR 3D

Technicolor 3D uses an “over-under” format that squeezes the left and right images vertically so both will fit on a single 35mm frame. However, Technicolor has called it a transitional format and expects digital to rule the day.

OCULUS3D

Oculus3D uses an innovative approach that rotates the left and right images 90 degrees so that more of the 35mm frame is filled and less light is lost. Oculus is betting on a long-term future for film.

PANAVISION 3D

Panavision 3D uses the same print format as Technicolor 3D and works with both film and digital projectors. It offers a shortcut for theaters that need 3D today and hope to shift to digital later.
