I agree that this is very interesting thread.
Dave, since you are using digital negatives, do you think that the starting point for three layers could be:
-first layer normal printing: this would set the highlights.
-second negative shall be completely opaque in highlights. Mid tones shall print like highlights (this would prevent adding density to mid tones as is the case with your tree layered print with the single negative
-third one would just add density to shadows
my thinking is, that shadow separation on second and third layers should be greater than with normal negative. Does that make sense?
I'm on a workshop this and next weekend, but will try to test this multi layer approach after that.
Cheers,
Marko
I should add that by and far this is the most pleasurable, informative thread I have had the pleasure to be involved in and learn from on any forum over the last 5 years.
Dave you deserve big kudo's from this community for sharing what you are doing.

Dave, I've looked at this worksheet over and over the last few years to try to decipher it. Thanks for bringing it up here...
Another thing to check is if Rives BFK was the same paper back then that it is today, in surface texture, weight and pH.
Almost none of the prints I saw in the Small Trades exhibit at the Getty seemed to show the familiar characteristics of BFK. They were, of course, framed behind glass, but I was sniffing as close as could be.
Have you also seen the margin notes on many of the prints? You can see them on test fragments in his "A Notebook at Random" book, things like "X8000 3'16" 15 min 3 x (PB).
I know about the Strathmore but are you sure about Penn's use of Bienfang?

This has been a very interesting thread. For my own experiments over the last few days; I have tried a two hit pt/pd print, using two negatives.
I'd been creating a new set of curves following a switch in printing workflow, and landed on a print with very open shadows. The highlights were spot on, so in a crude and spontaneous experiment, I recoated and layered a far denser negative with heavily masked highlights over the top. I wanted more depth in the shadows with little change to the highlights. Although my results were not predictable, at all scientific or refined, the results were almost as hoped. The mid-tones were brought up to better density, the maximum black increased (visual assessment only) and the highlights remained about the same. I would imagine through proper testing and curve creation, that prints of greater depth could be created.
While I'm not sure I would coat twice for general tonality, the increase in DMax was appreciable. These experiments are much appreciated David, and I look forward to seeing the progress. With the Kenro Izu series of Cyanotype over pt/pd, the depth of the bluish black shadow is beautiful. Once I have proper registration sorted*, I will experiment with Cyan hits on the shadows of Palladium prints - with a bit of luck creating a split tone of sorts with warmish highlights.
*I really fudged registration on the print below. If anyone could point me toward advice on using pins to improve the results, it would be much appreciated.

Good to see one of my recent platinum printing students, following in my footsteps.
Re registration issues
look at the image above your post. You will see that the paper is mounted to aluminum with the registration punch holes visible.
I use Strosser punch for all my past and future multiple hit prints. I will punch on the long side of the print. Penns prints I have seen here and at my shop were punched on the short side.
Also note that the prints I saw were paper both sides of the aluminum.
Also note for good registration one should punch through the paper/aluminum/paper to not have a air gap which over the long exposures would pull the film towards the punch holes and cause miss registration.
Punch pins are made or better stated, vacumn Exposing units like for example Nuark 26k have a rubber blanket whose sole purpose is to allow the pins to sink into them so that there is a perfect contact between film and paper.
Dave , does the exposing unit you use have a large blanket that will allow the pins to sink??? very important.
Laying down the film onto the pins is very critical and the decisive moment one would say for critical registration. Believe me when I say this as a bad laydown will only show itself after you have done the exposure and process and then it is too late.
This is one image that i have yet to upload from a while back when i was looking at the differences between the book reproductions and the actual prints that might be of interest to some. It shows quite significant differences in density, tone and hue between the two that is important to emphasise to those who have not seen the original prints which is a must for anyone interested in platinum prints or indeed Penn's work.
