Yes, 120mm film, the medium format that is so bad-ass it's twice as big as 60mm wide 120 ! "120mm" is my favorite misnomer in the world of photography. You can see it on the shelves of photo store, in the post of both newb and pro photographers, in the catalogs of laboratories, and I'm sure Neil Armstrong exposed a few rolls of 120mm in his Hasselblad camera on the moon! Every month or so, I patiently train a lab clerk at my local photo store (they rotate a lot, obviously) in the long forgotten lore that pictures on 120 film really are 6 cm wide, not 120mm wide, and that 120 really is a product code. Surprisingly, very few people say "220mm" but it happens every once in a while you will see it in product list (see these guys, for example: http://www.lozeau.com/services/comptoir-finition-laboratoire/films-diapos/developpement-120220/ or those guys: http://www.borealislab.qc.ca/pdf/liste_de_prix_01.pdf) because the same clerk who did 120mm was told to add "220". "120mm film" is a testament to the power of words: stronger than truth, easier to remember than reality, more coherent than the external world, and more meaningful than the original. So what's your favourite misconception in the world of photography?
