I work at a repair shop for a 9-5 as a non-tech, but I have access to foam, parts, etc, and I am very familiar with my nikons (yup- 35mm). I'm sure that static would normally be a concern, but I've seen examples of that, and this isn't static. It covers the entire emulsion side of the film, so light leak may be a possiblility. If it helps any, non-US Delta 100 was used, so I will try both repeating my process, complete with (possibly) too many rinses, with the same stock and some US-Delta 400 (change in dev. time, of course at ei 250), and see if I can replicate the results. The most offending areas were near the sproket holes(advantage to 120?), so maybe stricter mixing and agitation will be in order. If I don't see any change despite, I'll start eliminating rinses.(posted 8642 days ago)Thanks for the replies- Mike
