Ah, that Kodachrome! Seems a shame that we are near the end for what remains the MOST detailed (grain size down to individual molecules in a fairly dense array - nothing digital comes close, short of specialized military-spec satellite spy cameras you can't even buy!) and durable color film ever created. Kept in decent conditions, Kodachrome color should last at least a century; some of the earliest Kodachrome pics ever taken still show vibrant color. A few of the last films created could give it a run for the money on color accuracy, but it remained and remains one of, if not the, best film ever made.
Alas, it won't be around for too many more years, it seems. I have over 8,000 Kodachrome slides I took mostly when traveling (for work) around Asia. After trying all of the (back then) twelve processing centers, I used to send my slides to Japan for processing, since it was the closest lab and they did good work. Love that stuff!
It wouldn't be so bad if digital were an improvement, but not only is the resolution not there, do you really expect current digital pics to remain view-able 100 years from now? Theoretically, they could be, but it assumes the formats and software will not change too much, and/or that the pics won't suffer from too many conversions...assuming someone even bothers to convert them when standards change. Doubtful, at best!
Even Paul Simon knew Kodachrome was a good thing!
I'll shed a tear when the last Kodachrome lab shuts its doors, for the world will have become a little bit diminished, a little poorer, a little more deprived. That shouldn't happen in today's world!
