New Platinum/Palladium prints

The printing work on the new portfolio continues with two added images from that 5x7 series. These are the same images I printed thirty years ago, in the salt paper process. The close resemblance between those original silver images and the ones I'm printing today in platinum/palladium is fairly amazing to me. I see the Pt/Pd images a bit richer, deeper blacks and a bit better tonal separation over the silver prints.

These negatives are also don't have the density range of the earlier negatives I've been printing. Those negatives demand a twenty minute print time in full sun, using the 2 drops of 2.5% platinum solution to the palladium mix. The images I'm printing now I'm using 10% platinum solution to boost contrast. The print times are then half of the 20 minute time of the denser negatives.

This print is one I want to get exactly right. This test run was just a bit short of that. This was a twenty  minute print time, using the 2.5% platinum solution added to the palladium mixture; this image will likely need a 23-24 minute print time, full sun.
