Disc film

[1] The film is in the form of a flat disc, and is fully housed within a plastic cartridge.

The cassette has a built-in dark slide to prevent stray light reaching the film when the disc is removed.

Disc film did not prove hugely successful, mainly because the image on the negative is only 10 mm by 8 mm, leading to generally unacceptable grain and poor definition[2] in the final prints from the analog imaging equipment used at the time.

A problem with labs of the time was the manual nature of processing the color negative film.

The film was officially discontinued by the last manufacturer, Kodak, on December 31, 1999, though the cameras had disappeared from the market long before then.
