Used ASA 64 up-to 2009 when discontinued. Nikon Coolscan 9000 produced pretty good scans!Actually, that was Paul's alone... 1973 - There Goes Rhymin Simon...
Kodachrome had such different processing requirements, that you would be happy to wait a week to see your results. It is unfortunate that by the time high resolution scanning was readily available, most Kodachrome images had shown enough deterioration from age, to never be able to capture all the inherent resolution of the original.
