I want a trial in camera film wanted to play with the juice. Guess who is going to have more fun with? a Holga, a Diana or a fish-eye camera?
I have a couple and a 1st Gen Holga Lomo Fisheye, plus all 35, 120, 2x3, 4x5 and digital cameras can not be separated from him. Go to the Holga. (Get a new "N" model bulb setting. One with a flash "FN" is useful but w / o flash has a hot shoe so you can put a flash in this low price or to connect to studio lights.) Dollar per dollar, the Holga is more fun. If you can send your own b & w NEG better, because the processing of 120 films will cost $ 4.7 a roll. If you not have access to a darkroom, scanning the 120 NEG on a flatbed scanner (I a CanoScan 8400F) in Photoshop gives great control. Use ISO 400 + film unless in sunlight or in a studio. An alternative to b & w film is a film of black and white (Ilford XP2 or Kodak C-41 Tmax) that can be treated easily in many Fuji, Konica and Noritsu film processors minilab. Enjoy!
