Question for PE:

I recall reading one of your posts a few months back about the high speed positive film breakthrough that Kodak made. I think you had written that, while it's unlikely to reach the market, it would be possible to boost the speed for your handmade emulsions with the same principles. I'm just curious if that idea ever went anywhere, or if there have been any details (patents, etc.) published about the process. Thanks.

Paul Gilman has told me the general idea behind doing it, but I need two chemicals that I have been unable to lay my hands on.

The patent is published.

I see from a search of Gilman's name that it's patent # 7,183,024 in case anyone else is interested enough to want to read it.
