can't wait for your next upload!

This is from a 2 1/4 x 3 1/4 paper negative shot in a Polaroid holder in a Polaroid back in my RZ 67.

That was ISO 100. I am now at 200 and working on ortho sensitivity.

This is mouth watering stuff!!
I cannot wait, until you have a saleable product that I can obtain.
I'll never get to one of your workshops, being this far away from the USA.

Ok, this is an ISO 200 (hopefully) ortho sensitized emulsion from last night. I have not had a chance to expose it in-camera, but you can compare the wedge spectrogram with the previous ones as they were all made at the same exposure time and intensity.
The apparent red sensitivity at the right is due to the huge overexposure and a harmonic in the spectro sensitometer, as I didn't have a UV filter in place.

And here it is.
ISO 200, ortho sensitive from a paper negative, inverted to make a positive.
I should add, this was run #1, the above wedge spectrogram confirming it was run #2 and has not been used in-camera. I used a different method in the wedge spectrogram above to help stabilize the image and reduce fog.
It worked.

I have all of this on film support as well, but the weather has been so crappy here in Rochester that it is like twilight at noon.
As soon as I can, I will expose the film examples. I expect them to be about ISO 25 - 50 but less grainy and sharper. The apparent grain you see are paper fibers and they also contribute to the apparent lack of sharpness in paper negatives.
It is hard getting the film support. I just have a small supply and I want to reserve it for the workshop and for my own experiments. I'm working on getting a bigger supply.

Nice work here, PE, we love seeing this kind of stuff; definetely keep us posted on these advancements!!
PE, this is all well above my head but very interesting nonetheless. I can see your current efforts as being very worth while in the future as further cuts in commercially available B+W products further limit our options. Good luck with it. Have you considered gathering a team of ex-Kodak employees/engineers and starting a small production company? That would be very interesting to say the least!
