120 film

120 is a film format for still photography introduced by Kodak for their Brownie No. 2 in 1901. It was originally intended for amateur photography but was later superseded in this role by 135 film. 120 film and its close relative, 220 film, survive to this day as the only medium format films that are readily available to both professionals and amateur enthusiasts. As of December 2018 all production of 220 film has stopped/paused worldwide. The only remaining stocks are from the last Fujifilm production run (2018) and they are mostly found in Japan.
