I as well played with E6 about 16-20 years ago. I remember the joy of seeing full color film on those reels when I opened the tank. It required good temperature control (a bit smelly), but that was about it.(posted 8219 days ago)Recently, looking for some old materials, I ran across the hand done E6, and what would you know, they still look great and don't seem to have been effectived by time, so the kit must have been OK in terms of longevity.
