Thanks Mr. Bill for that info. I remember when I worked at B.G.M. colour lab in Toronto in the mid to late 70's when we were in the process of converting from C-22 to C-41 that we kept getting film marked "Vericolour" no I,II, or III and someone pointed out that it was process C-22 not C-41. Before that, some of this film accidently made it into C-41 and gummed up the processor because of the temp. differences.
