I agree with Katharine, Paul. A quick shot with Ivory Black
should accomplish what you want!

I'd use ivory black, not too heavy (at a medium-heavy concentration, it's a
lovely dark chocolate brown color, the color of bittersweet chocolate) to
fill in the shadows; that would anchor your image well, IMO.
The
pigment concentration should vary with the pigment, but what you're done
here looks okay to me. The earth pigments are weaker as a rule than
some others, but your burnt umber looks good there for midtones.
You'll never be able to print the burnt umber dark enough to really
give dark shadows, it's not in its nature, which is why I'm suggesting ivory
black for the darker parts.
Glad you're having a printing day that
doesn't require chugging the Everclear,

1st
layer: Burnt umber 5 1/2 minutes
2nd and 3rd layers: Raw
umber 2 1/2 minutes (1 gr pigment / 2 ml gum) Is this
concentration high enuff?
I think 2 1/2 min is not enough time with
these Pd negs...I'm thinking 3 1/2 m

Yeah,
I'd say hit it with a really heavy pigment concentration for a short
time for darker shadows. What's your pigment?

Any scans or shots of the images? There has been a dearth
of new alt prints in my life as of recent.

I should've been
more clear...I'm getting better gum results from palladium negs than
using less contrasty negs for gum. My palladium prints print
wonderfully with the palladium negs ;-)
This would be a huge
advantage for me, in not having to keep track of two different
styles of digital negatives.
Now, I'm wondering how the
palladium negs will work with tri-color gum...only one way to find
out!
