Interesting thread, and interesting info on the Tentenol kits not being good for "newer" films. I only tried color once and it was with one of those kits on some old (10-15 years) film, a mixture of Kodak and Polaroid C-41 35mm. Oddly, when doing two rolls at once, I had some experience where one roll would be good and the other virtually blank. I'm starting to wonder if the "weak" chemistry in the kit had something to do with it, and if I would have had different results from Kodak chemistry.
