I agree...slide film is beautiful. I am concerned, too, that it will go away. There is no more direct printing from slides. I used to do that in a darkroom I worked in at a custom lab. That was the best experience I ever had working in a lab...getting to print from slides in the darkroom. Especially from professional work...the color saturation is stunning, and I still believe that scanning and printing cannot compare to a direct print.
Anyway, enjoy those slides! I love looking at old family photos of any kind. Plus, keep shooting the E-6. The key to keeping it around is showing a demand for it!
