Yep they are from that book. I hope I don't end up in jail....
I'm up to about the same... nothing! No but really, moving forward on dichromated gelatin dye-transfer matrices (albeit slowly), still thinking about autochromes and Lippmann, but mainly just working to scan all my old film, print in the darkroom and then everything else, a.k.a. life.
SF has yet to do said screen-plate photo, but I'd bet someday we'll see it. Maybe he's waiting for someone else to step up to the plate. If I could just have a week off someday, I'd get so much done, but alas, that's not gonna happen.
By the way, have you made any panchromatic emulsions lately? If you want me to send you a screen-plate, let me know.
