My son asked if he could have a go at film photography, so I dug out an old Minolta Rivas compact, my dads (point and shoot) old Pentax p30 with lens (fully manual) and my old eos600 with sigma 28-80 (semi manual if using green square setting). Anyway he and his girlfriend got a new film and battery for the canon, took some photos that came out pretty well. The minolta already had a film in it so I suggested they use that up with no expectations if it would come out. To our surprise not only did the camera work well, the film developed ok, including some pictures of my son aged about 7, he is now 21! These included him in fancy dress for world book day and Australia Day at school and his first scouts uniform, what a treat. So, the film had been in the camera half exposed for close on 15 years and was still fine. Amazing technology. And the look of the old film, even when scanned in, is still very appealing.
