Up until last week I would have yearned for the return of old Kodachrome and its longevity. This weekend, I found a carousel of Kodachrome slides from a college trip to Europe in 1982 that had been missing since 1992. Most of them were underexposed (most likely the fault of my Yashica MG-1 not dealing well with overcast days), and about half of them have multiple fungus spots. The fungus appears to primarily affect the sky and can be easily remedied by hybrid technics, fortunately.
As I actually go back and review my old Kodachromes I realized how many of them were not properly exposed. I have fond memories of the film, but I suspect it is because when Kodachrome worked well, it was spectacular. I'm much older, much more experienced, and have better equipment than I did then and would probably have a much higher success rate with Kodachrome today. But, I assume I would be just as happy with a modern E-6 Kodachrome-like film.
Despite my initial excitement about Kodachrome's possible resurrection, I am now reminded of why I hadn't shot that film since 1982.
