Re: for Marek
Well, now I'm confused. Paul said he was following my insttructions
on my web site for determining exposure, which call exactly for what
Marek is suggesting below except that I use four strips instead of
three, and I was trying to figure out how he overexposed so much
following my instructions, which I thought should have been pretty
straightforward. I thought he was understanding our conversation;
his replies seemed to be making sense to me, even though we were both
drinking Everclear. But if he wasn't using Stouffer strips, and he
wasn't following my instructions, then I don't know how he determined
the exposure but glad to know it wasn't something in my instructions
that sent him wrong. Either way, my comments in response to the
yellow print he posted remain the same: too much exposure, too
little development.. Seems pretty uncomplicated to me.

Paul,
This is simple, or at least in my mind.
First foreget the negatives,
Then coat a piece of paper with blue emulsion. Yellow is a terrible
way to calibrate the system since you can't see it very well. Take
your 21 step wedge and a piece of clear transparency that you are
using. Place the wedge on top of transparency and expose 3 strips.
1 minute, 3 minutes and 4 minutes. You should develop until they
more or less stop developing, about 30 minutes. Post the results to
the alt community, you will get a lot of positive feedback. This
really opens your eyes to the understanding of the process.
This will establish a correct exposure/development. It will not
change much if you increase strength of your pigment.
As far as negatives, I am printing on 3800 with photo black and
yellow at 25% strength with no curvature in QTR. You do want to
curve in photoshop to place middle grays where you want them.
I was actually impressed with your last yellow attempt. If your
were doing monochromatic gums you would be very close to a sweat spot.
