While walking along a trail in Death Valley NP last week, with a Nikon F3 slung lazily over my back, a fellow with the newest Nikon DSLR camera (as he pointed out) asked me "is that an old Nikon film camera?", plus some other related questions. He said that he had not used film since 2007, and went over the usual advantages of digital cameras, which I agreed with. But I told him a main reason for my not using a digital camera was the cost -- I just don't take that many pictures to make it worthwhile, plus I prefer film anyway, for the usual reasons besides economy. That day, I finished up a roll of 36-shot slide film that was in the camera since the end of September. I also took 16 b & w shots with my 6 x 9 folder during the week-long vacation. It was a very nice conversation, by the way. The F3 is the newest, fanciest camera I own, and maybe it's good I was carrying it instead of the folder.
