Roll film or rollfilm is any type of spool-wound photographic film protected from white light exposure by a paper backing. The term originated in contrast to sheet film. Confusingly, roll film was originally often referred to as "cartridge" film because of its resemblance to a shotgun cartridge.

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 It was originally intended for amateur photography but was later superseded in this role by 135 film. 120 film survives to this day as the only medium format film that is readily available to both professionals and amateur enthusiasts.
