All those years I didn't take slides because I wanted prints and getting them from slides was expensive and problematic.
Now that 99.9% of commercial prints come from scans, slides make much more sense.
I came back to film after the Kodachrome kill-off and in the last year of processing people were selling Kodachrome for $25 a roll. So I missed out on Kodachrome.
I tried some Ektachrome and loved it but now they killed that dead too. I bought 40 rolls before it was gone and I shoot one every month or two. I love to project them with my $30 Leica projector I got from Ebay.
