116 is a roll film introduced by Eastman Kodak in 1899. The film stock is 70mm wide. In 1932, Kodak introduced 616 film. The film is the same but the spool is the same width but with a slightly slimmer core. Kodak discontinued both 116 and 616 in 1984.
The Film Photography Project is committed to offering 65mm and 70mm film so that you can DIY (Do-It-Yourself) and roll your own.
