Here's the print scan!


This is the print I made yesterday. The usual disclaimers that the print color is slightly off in the browser, as well as there being more detail in the sky highlights than shows on the scan, etc, etc, blah, blah...

Hope y'all like it...

It did seem a bit wet when I brushed it on...and you're absolutely right.

I usually use .5ml for a 4x5 print (pure pd, amm citrate), but lately that has seemed a bit less and got a better print last time with .75ml. I extrapolated from that figure, which gave me 4.5 ml, but I knew that that was way too much. So I knocked it down to 4ml, knowing that I'd rather err on the side of more solution...3ml is definitely what I should have used.

I use a 2 1/2" DaVinci Cosmotop brush, a $40-50 synthetic flat watercolor brush, which I love (used a Dick Blick 40% off coupon!)...

Paper is Fabriano EW, acidified in oxalic acid 1%, 3 minutes...pre-exposure humidity only

That color shift is expected. I would also attribute the smoother tonality
to the potassium oxalate developer.

What paper are you using and what are you coating with? With a paper like
Platine or COT320 and a Richeson brush, that's more sensitizer than you
should need. You should be able to coat a 9x14 area with about 1.5 ml each
of Pd and FeOx.

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.
