Ken,
That would be great to stumble onto Phil's secret chemistry
tricks....in any case what was your process for removing the Kodak
backing from the reversal Kodachrome? The way I understand it, the
crux of the matter is getting that stuff off your film after its
processed.
btw, are you in the sf bayarea?
