David, You concluded that I'm "a bit of an anti-digital zealot". That is not strictly true. In fact, my problem may have been that of an early digital adopter. I started with a Canon G1 in 2001, progressed to a Fuji S2, later a Leica DMR, and then reverted to film capture for a number of reasons. One being that I was uncomfortable with the camera life cycles and cost. Canon is now on a G10, averaging about 1 new version every year. I continue to shoot digital in the studio. I shoot film on the street. I think that we may indeed see the end of almost all film within the next few years. Maybe I just want to shoot it while I still can. I started to think about this longevity issue when I digitized some 200 or so negatives my Grandfather shot in the 1920's. The recent announcement of Kodak about Kodachrome revived my thinking about it. I appreciate your thoughtful answer to my queries. Steve
