Film '''base''' is a type of flexible material used as a foundation or base for film [[film emulsion]]. Film emulsion is made up of light sensitive silver halide grains suspended in a gelatin coating. Film base is sometimes referred to as the "support" as it is the supporting material that the emulsion layer is then coated onto. Throughout history it has been made of different materials, all of which require different handling techniques for projection as well as storage. | Film '''base''' is a type of flexible material used as a foundation or base for film [[film emulsion]].

*''A note about the common usage of the term "film stock". People often use "film stock" interchangeably with "film base" to refer to the physical material upon which the film is printed as identified by the composition of the "film base". This is a colloquial use of the term. The proper use of [[film stock]] is to refer to film manufactured by a specific manufacturer, or that is associated with specific properties of the emulsion like color saturation or development speed etc. For example, you might say "this film was printed on black and white Orwo stock" or "Kodak 2383 stock".'' | |||
