I just returned from a three month long vacation (don't know if you can still call it vacation when you are retired?). Every year I shoot some of my remaining stock of type 100 Polaroid film to see that they are still working. The expiry date is 2014 for the Fuji FP-3000B, but they still give good results. I wonder if they get more light sensitive when they age, I had to shoot these at 12800 ISO to get the correct exposure.
