This list is believed to be accurate, but by no means complete. The names listed here all share their basic specifications with CinemaScope, i.e. 2:1 anamorphic compression of the photographed image and complementary expansion in projection. Many of these systems were merely names assigned to anamorphic films by a specific studio and don't necessarily indicate any particular optics manufacturer or compression method.

*   Some or all films carrying these system names were actually produced in conventional "flat" widescreen and anamorphic optical prints were made, similar to the Superscope system, but with even less quality.

**   Scanoscope was a bizarre two perf photographic and print system that resulted in a print that was run forward and then backward through the projector. More coverage is planned on this oddity.
