Photo Forum / Film Photography / 35 mm / September 2007Film Storage question
I left a few rolls of unexposed Kodak 400 color print film in a warm place (passenger vehicle, ~80 degree F peak outside temperature) for about a week. In your experience is this film ruined or is it usable? (Kodak says to store at 70 F or less so it's definitely out of spec.) Thanks, Steve >I left a few rolls of unexposed Kodak 400 color print film > in a warm place (passenger vehicle, ~80 degree F peak outside [quoted text clipped - 6 lines] > > Steve Well, I'm not a pro, so it isn't really important to me, but I have left unexposed (and exposed) rolls of film in the trunk of my car in the Summertime for a week or more many times, and I have yet to find a "bad" roll yet.....Of course, I don't inspect my finished shots with a microscope either........But I'm sure it has spend many hours at 100 degree temps or more. So, In general, film is pretty tough stuff..... > I left a few rolls of unexposed Kodak 400 color print film > in a warm place (passenger vehicle, ~80 degree F peak outside [quoted text clipped - 6 lines] > > Steve My advice is if you haven't exposed them yet, bite the bullet and discard them. If you have then process them. Most likely they'll be OK but film isn't that expensive (depending on what you mean by "a few rolls") so that if they're unexposed, trash 'em.

This might be a good time to "practice" some composition or other "stuff" you would not ordinarily do, take them for the cheapest processing and it might be a learning experience for minimum $$$, you already did pay for the film anyway. > On Sep 2, 4:06 pm, spop...@speedymail.org (Steve Pope) wrote: > > I left a few rolls of unexposed Kodak 400 color print film > > in a warm place (passenger vehicle, ~80 degree F peak outside > > temperature) for about a week ... film ruined or is it usable? > Steve, [I] would not use them for anything serious. My guess is that the film has suffered no damage. What about all those 90+ days in the summer - who chucks the film in the camera bag if the temperature gets above 70? However, if you mean it spent a week on the dashboard of a closed all-black car parked in the sun, but the outdoor temperature didn't get out of the 80's, I wouldn't use it for anything important. The 'expense' of taking the pictures outweighs the few dollars the film costs. If you had to re-shoot the whole roll and value your time at $5.60/hr to $560/hr you can figure what it costs you to take a chance. "When in doubt, throw it out" OTOH: I keep all sorts of abused film, as uw suggests, for finding out 'is this shutter/meter/camera working ok?' The Kodak rep at the last Large Format conference in Rockford mentioned that in freezing color film it loses its ability to resist heat. He recommended if you freeze color film you should use it and have it developed ASAP. So if this film has been spending time in the freezer then the risk of it having gone off is greater.

In considering questions like the above, ask yourself: Where did the film come from, and how was it shipped to what warehouse, and what were all the temperatures involved. Was the truck used to ship it across the country air conditioned? Was the ship used to ship it from Japan air conditioned? Did they store it in an air conditioned warehouse, and did the store that you bought it from keep it in an air conditioned space prior to selling it to you? I buy most of my film over the internet from places like Adorama......It gets to my house on a UPS or Fed-X truck that is not air conditioned....How long it sits in that truck and under how hot a sun are questions that I can't answer.....I keep it in a refrigerator in my garage, but it is quite possible that it was destroyed before I ever got my hands on it. > OTOH: I keep all sorts of abused film, as uw suggests, for finding > out 'is this shutter/meter/camera working ok?' Self-contradictory statement: if you believe the film is not useful for a roll worth of shooting you can't know if the EI of the film has been changed by the heat. This is all BS of course, there is nothing wrong with a film that has seen a few days of moderate heat stress. Other than color accuracy, there is little doubt that this film will work fine.

Don't worry about it unless you're doing a job requiring high color accuracy (eg: advertising where color accuracy is required)...

OR, you're at an Art show and these great photographs are for sale: $3.00 ea. Save them for test rolls. Bob Hickey Thanks again for all the replies. To answer some of the questions, the film had not been previously frozen and was bought at a Long's in Ukiah, California so it perhaps had some previous lifetime in the heat. I am not a pro photographer, I guess I will use these rolls for casual non-critical projects. Thanks again, Steve > Thanks again for all the replies.

Really, don't sweat it. (And film is always "frozen" ... it's a solid. You could say, "kept in a freezer") Signature-- r.p.e.35mm user resource: http://www.aliasimages.com/rpe35mmur.htm -- r.p.d.slr-systems: http://www.aliasimages.com/rpdslrsysur.htm -- [SI] gallery & rulz: http://www.pbase.com/shootin -- e-meil: Remove FreeLunch. >I left a few rolls of unexposed Kodak 400 color print film > in a warm place (passenger vehicle, ~80 degree F peak outside [quoted text clipped - 6 lines] > > Steve This is a CYA statement from Kodak. Even so, they mean months or years must elapsed before noticeable change occurs. If you really want to keep it for a long time, store the film in the refrigerator. Jim >I left a few rolls of unexposed Kodak 400 color print film > in a warm place (passenger vehicle, ~80 degree F peak outside [quoted text clipped - 6 lines] > > Steve If that 80 degrees is correct, the odds are perhaps 99% that the film is still OK. However, a closed car outside in the summer sun can easily go over 100 degrees. A week in that, and I would probably use the film for experimenting. There could be a color shift, but it probably will be easily correctable in printing. Bottom line, I would probably use the film, but only for shots that I could repeat. And I might use fresh rolls alternating with the "temperture impaired" rolls. The film I use for paying customers is in the refrigerator. > I left a few rolls of unexposed Kodak 400 color print film > in a warm place (passenger vehicle, ~80 degree F peak outside [quoted text clipped - 6 lines] > > Steve Semi-usable, but you might get some funky results. |
