Awesome things to hear!! Congratulations! I'm getting excited, too; have to buy some acetate. I have the chemicals for subbing layer as referenced by PE in some old post. I bought them before I started PET corona experiments. I'm very interested in more specific information; especially the method of applying the subbing layer. Is it with the same coating method (blade etc) than the emulsion itself? Or have you tried spraying? The layer is probably very thin?
Can you tell your source for diacetate? I thought it wouldn't be easy to find.
I'm looking forward for your report in The Light Farm!
