how long will it last in the camera?

  1. I shoot with an RZ and soon an M7, I dont always finish a roll, well sometimes, when I am done taking the
    pictures and I have some frames left I just blow them away quickly just to use the film up.

    My question is how long will film last in my camera? I shoot with most types of film from transparency to
    negatives.

    what happens to the film in the camera after some time? I keep my camera gear at room temp, but my
    rolls always go back in the fridge...
     
  2. It depends on what type of film it is. Slower films last longer before begining to fog, and Black and White films last longer than color films. As long as the temperature is not overly high, and you are going to be developing in a few months you should be fine. I think the maximum time I've left color print film in camera is about 9 months (ASA 100) with no noticeable color shifting or fogging. I mostly shoot Black and White, but I do use some E-6 from time to time, and I never worry about it. Then again, I usualy develop in the range of an hour of so after exposure to a week or two...

  3. ok, thanks thats good to know, I was getting worried that my film would expire, but those
    lengths of time I have nothing to worry about.

  4. Watch out for film curl if it stays in camera.
     
  5. Why would there be more of a chance for film curl in the camera, compared to the cassette? Do some cameras roll the film on the take up spool backwards,(emulsion out)?
     
  6. My experience is that film does better in canisters, where the curl is uniform, than in film backs, where you have both curled and straightened areas of film. If a roll is unfinished and has been sitting for a while, the shot about to be taken can often be so off the film plane that image sharpness is compromised. I've seen this all the time on Hasselblads, as well as on some 35mm cameras. It's one of the reasons Contax came up with the vacuum back option for some of its cameras.
     
  7. What kind of film? Latent image keeping (LIK) varies not just by
    speed but by emulsion. NPS is remarkably poor at LIK for a 100-160
    speed film. Supra 800 was unacceptable to me after 6 months in the
    camera. Amateur films usually have the best LIK properties but are
    not available for medium format. "Process promptly" as it says on
    the box.
     
  8. Superia 800 is surprisingly good in the LIK department -- better than many slower films -- but it's not available in medium format. Perhaps 800Z (NPZ) might be similar.
     
  9. used to keep un-canned rolls of 3200 tmax in my backpack for a couple weeks at a time and they would show fog streaks on the first couple frames sometimes.
     
  10. so lets say I go on holiday, take the mamiya 7 with me and 1 roll of 220 film and take three weeks to take a set of 20 shots, will it be ok to develop? What are the time frames with dev? Will I see a difference after a week after exposing the film?
