Disc film is a still photography film format intended for the consumer market, and was introduced by Kodak in 1982.
The film is in the form of flat discs, and is completely stored in plastic cartridges. Each disc holds fifteen 10 Ã- 8 mm exposures, arranged around the outside of the disc, with discs rotated 24 Â ° between each image.
This system is a consumer-oriented product, and most cameras are self-contained units without expansion capabilities. Film discs allow them to be compact and much thinner than other cameras. The camera is very simple to load and unload, and generally fully automatic. The cassette has a dark slide built-in to prevent stray light reaching the movie when the disk has been removed.
When the movie is played on the disk instead of on the roll, the cassette is very thin. The flat nature of the format also leads to the potential (potential) of greater acuity over the curved spool-based tape format (such as Minox, 110 and 126 films). The film disc has a very thick acetate base, a thickness comparable to the 4ÃÆ' â € "5" sheet film, which holds the films flatter than other time formats.
Disc films have not proven to be very successful, especially since the images at negatives are only 10 mm to 8 mm, leading to generally unacceptable grains and poor definition in the final print of the analog imaging equipment used at the time. The film is intended to be printed with a special 6-element lens from Kodak, but many labs only print discs with standard 3-element lenses used for larger negative formats. Printouts often disappoint consumers. Some laboratories make the investment necessary to get the best out of a small negative size. The problem with the time lab is the manual nature of color negative film processing. This is basically a manual process, unlike a spool based movie, whose chemical processing can be fully automated.
The film was officially discontinued by the last manufacturer, Kodak, on December 31, 1999, although the camera had disappeared from the market long before that.
There are different disc film manufacturers. Kodak produces films throughout the ages of complete formats, but 3M, Konica and Fuji also produce Disc movies. While Kodak movies are always eponymous, 3M and Konica make Disc movies for many third parties, branded with the retailer's logo. Like most photographic films, for such white-label products, the manufacturing country provides the best indication for the real producer.
Kodak's latest ideas with sharp sharp negative movies are always tested in the first Disc format, usually being one or two generations in front of 135 equivalent films.
The 1983 "Minolta Disc-7" camera introduces its predecessor from the selfie rod - a convex mirror on its front to allow self portrait composition, and the packaging shows the camera mounted on the stick when used for that purpose.

Modern usage
There are still a small number of laboratories left in North America and Britain that can develop unprocessed disc films. An example is from April 2017:
- Rescue International Movie
- Rapid Photo Imaging Center Inc. International, USA
- Blue & amp; Machine USA
- Photo Dwayne USA
- MS Hobbies UK, Europe
- USA Photo Citizens
Disc films went out of production in 1999. Expired films are available at the specialist stores above: the Kodak VR films manufactured before 1990 seem to be better than the final produced disc films. 3M/Ferrinia/Truprint derivative brands do not age well.
