I don't buy outdated film but I'm sure many people who do get good results with it but it seems to me to be false economy to take the trouble to spend all the money we do on equipment and worrying about the technical quality of our work not to mention lugging our gear all over the place to jeopardise the possible outcome of our efforts seems to me like like a cook making a meal with food that's past it's expiry date, the results are unpredictable.
