This is a blended platinum/palladium print (60% platinum, 40% palladium) print, on Bergger COT320 paper. This was by a student from my Intro class, but I reprinted it for this session (the student left the negative behind after the Intro class, and I happened to really like the shot anyway). This one was coated using a glass rod as opposed to a brush, to demonstrate the difference in the coating technique, and the final appearance of the print.
This is a palladium print on light Kozo paper, by Patrick Brown, one of my students in Advanced Topics. He was also in my Intro class. It’s so nice to get follow-on students so you can see their progress!
Kozo paper is a Japanese paper made from tree bark, and it is surprisingly strong for as delicate as it is – this is perhaps a 90 lb paper. It does have a tendency to dissolve in aqueous solutions, but if properly masked when developing, the image area can be preserved, even if the edges do get fringed a bit. This is a perfect example. I included the paper margins to show more clearly what the paper texture looks like.
We had some challenges this class session – the original idea was to try out some different paper types, and I had obtained a sampler of several kinds. We started the morning with Stonehenge, which was supposed to be a good paper, but something was dramatically wrong with the batch we got, as we were making 30 minute exposures and still coming up weak and flat. After this is over, I’ll get a little more for myself and try pre-acidifying it to see if that helps, but no mention of acidification was made in the sample kit and I couldn’t find any reference to acidifying it online. Fortunately we didn’t waste too much time before figuring out it was the paper at fault and not the chemistry, and life moved on.
