Re: palladium bleeding, loooonnnnnggg results

Bob and Eric and Camden,
I am avoiding getting in the car for 5 more minutes to drive 900 miles :)

Bob, simple is NEVER ignored or chided, by me anyway.

WOW, you use a hair dryer to dry? I will list that as another thing to try.
But as Camden said in his post, it is dry enough in MT that paper here will
dry within 20 minutes.

The cockling, as Don calls it, that Camden talks about does happen here with
Platine. It is because the very edges have a bit more solution on them, and
the center dries fairly quickly here.

But Bob, your hair dryer method on the edges might be just the ticket to
solve that issue.

The ferric I used was different than Camden's which I had ordered from B and
S about...when, Camden, March? I reordered from B and S another bottle.
But I just had to quickly order a liter of the stuff because I was running
out, so I got the new ferric from Photographer's Formulary. Maybe with the
hot weather my ferric....went belly up or somethin'.

Camden, as far as the paper, I had ordered 75 sheets of the stuff, in 3
packets. Therefore there could have been 3 different batches although they
were all ordered at the same time.

My rH now (Camden, I got mine at Brookstone, a digi/temp indoor outdoor
readout for maybe $30?) is around 30-40%. But where Camden prints is in the
school building which is climate controlled, and I print at home in my
dimroom. Montana is verrry dry, even when it rains. I will be interested
to see how Mark Nelson (and Camden, because he will be Mark's assistant at
the Formulary for 2 wk) find the humidity at the Formulary during his two
week workshop there doing diginegs and pt/pd with Dick Arentz. But he's
been there before.

Eric, as far as if I observed different speeds/etc. with different amounts
of ferric, etc., I am bringing the tonal palettes, which will show me all
that, on the road with me to observe; didn't have time to do so yesterday
because of a wedding, but I'll have a 15 hour car trip to look so will
report back. I do know that the bleedoff increased with increase of ferric
and it became greyer and ugggglllly.

I think this answers all the questions--OH, Camden's paper was from the
first 2 batches/packets of Platine, which I also used; I don't think he used
from the 3rd packet because I brought that home at the end of the semester
to finish my New Orleans project.

I do suspect that through all this, humidity, new paper, and a dab of
something to allow the solution to sink in better, along with fresh ferric,
will do the trick.

Bye--on the road again, with spotty email, but maybe I'll be able to post
speed results within the next couple days if my computer doesn't crash
again!
Chris
