Re: Samples of Pd with Na2

Yeah, Neal...nice!

Kerik, I ran a few test strips yesterday before doing the 11x15 (9x13.5 image) and the pure Pd w/o NA2 was slightly warmer than the one with it.

Also, I could've run the print w/o NA2, but the one with it gave it just that slight bit of punchiness it needed, seeing that the image goes from dark areas of foreground to a hazy aerial perspective in the mountain. The PO (or maybe it was the NA2) gave me a smoother print than I had been able to make with pure Pd and amm citrate developer.

The biggest worry I had was coating a larger-than-my-usual print. I used 4 ml of solution plus 2 drops 10% and 1 drop 2.5% NA2. I extrapolated this from my test strip which used .5ml of solution and 1 drop 2.5% NA2.

Scan to come...

Neal these are looking good. The colors seem to be all over the board,
though. I presume this is the result of scanning and adjustments rather
than the actual color varitions in the prints. I'm surprised you're seeing
a change in exposure time and smoothness with a relatively small amount of
Na2. That has not been my experience. A slight shift from warm is expected.

I haven't posted samples of my work previously, but thought, given the
recent talk of Na2 with Palladium, developed in PO, I'd post a few links,
as this is my process. I used to work with the Weston, but now use Arches
Platine. Some of these were also printed on COT 320. I struggled for a
long time with DR, and only recently feel I've gotten a good effective
speed for my film (now FP4 after a year with HP5 and two years with TriX),
and my developer (HC110, Jobo tank, Beseler motor base), and I can run with
a very, very minimal application of Na2. Na2 is great, but with much more
than a drop of 10% in a mix of 16 drops each of Pd and FO (for an 8x10), it
shifts the color, it makes for less smoothness, and it impacts exposure
time. I feel like zero Na2 is also not a good formula for me. Seems like
the coating is more even, color is better.

So, these are some examples of 8x10 portraits. I also shoot still life and
hope to scan and post some of these soon.









Thanks for any feedback.
