film size

  1. Could you give me some info about
    cameras. I am using a Nikon F3 35mm, so I know what 35mm stand for. What
    I'm confused is what size of film for medium and large format cameras?
    what is the difference between 120 vs 220 film? and finally what are
    5x7, 4x5 and 2x3 films?
     
  2. 35mm film comes in canisters.
    Medium format cameras use film which comes in rolls which
    are 6cm wide. The picture format are (all in cm):
    4.5x6, 6x6, 6x8, 6x9, 6x12, 6x17. There are two types of
    rolls, 120 and 220. 120 film is thicker because of a paper
    backing, therefore you get two times less exposures per roll.
    Large format cameras use sheet film (therefore the picture
    format and the film size are identical). The popular formats
    are 4x5 inches and 8x10 inches, but other formats are also
    used. 2x3 inches is 6x9 cm. There used to be sheet film of
    that size, but i have not seen it recently.
