I've been taking quite a lot of photographs recently (trying to make the best of the unfortunate situation we are all in) and have been using some b+w film up to 14 years "out of date" to see what happens. I have learnt, a) film 14 years past its use by date, NOT kept in the fridge, seems to work perfectly. b) Print developer less than 24 hours old (mixed) which we are told should be ok, really isn't. Horrible muddy prints and not even worth trying. What age film do most people give up on and not load in the camera?
