How far expired can film be and still be useable? I found some Ilford iso 50 that says Jan. 1975 and Aug. 1980. Also have a Konica InfraRed 120 that expired 1998. After that, my "fresh" film is mostly iso 200 exp. 2003. Interested in using them even if they produce only Lomo-esque Diana type pic.s. |

I've gotten good results from Plus X at over 25 years old, and that's faster than the Ilford, so I'd expect if the film has not been stored badly you might do all right with regular black and white. Infrared film, I'm told, doesn't age as gracefully, and is likely to fog pretty badly, but I wouldn't write it off without trying a roll anyway. |

I've found it depends on the film type and also how its been stored. My experience is that black and white film still works but gets weaker as it gets older (ten years plus). Colour negative may suffer some colour shift but is generally robust, especially the consumer grade stuff rather than the Pro film which tens to be more sensitive to heat etc. Slide/Chrome film is the most subject to change. I bought some really old Agfachrome (20 years) and the colours were really all over the place and lots of green spots all over it too. Kind of interesting but I haven't shot any more of it! I go for refrigerated under five years now. |

I once was given a folding kodak about 1920 vintage, film was still in ikt. I rolled off remainder and souped in tray development. The pictures were very old about 45 years old and still good. Keep bulk film refrigerated or if not to be used sealed and frozen. It keeps well. as stated black and white seems to fair better. Recently I was given a 126 color 200 asa film and sent it to blue moon for souping. four shots still remained. Heat and humidity are the worse things for film also x rays. Don |
