Re: Overexposeure was Re:Pinhole gums
Diana, I keep thinking you're gone, but if you're still there, two
quick questions:
(1) I'm confused about the conditions under which you're having these
printing problems. Was it only when the weather was cold and dry, or
is it any time you use the paper that was sized when it was cold and
dry, regardless of present conditions?
(2) You said that brushing "helped" but that the image essentially
didn't develop; I don't understand that. Are you saying that even
with brushing, the image didn't fully develop, or that brushing after
a long soaking that didn't develop an image would eventually result
in a fully developed image?

Hey Mark,
That's a thought. As advised by the woman at Photographers
Formulary, I keep the bottled glut in the refrigerator, so when I
get ready to use it, I take it out and have never even bothered to
warm it up-- I just add the required amount in the warmed up
gelatin. But I guess that could have happened. I did have the
gelatin in one of those electric glue pots that keep everything at
a constant 140 degrees, so it stayed warm-- until I was coating,
but I was very quick about it-- I think maybe it just dried too
quickly. I also used different types of paper when sizing, both
Fabriano and Rives BFK, and got the same results from both. The
only difference in what I normally do was the (relative) excessive
dry cold.

Could it be that the hardening agent you are using for the gelatin
did not activate in the cold well and then when you coated with
the gum, it was causing a hardening of the gum?
I would try sizing a sheet in "normal" temperature and humidity
and then try a gum print on it and see what happens.
Fall seems to be when lots of people have problems with printing
due to changes in temperature and humidity.

Hey Katharine, David- Still here-- we were on our way out the door
to catch a ferry to get back home, and then our cat managed to
hide herself so we couldn't leave. We finally found her hiding in
a closet-- anyway-- as far as overexposure-- that is what it
sounds like, though I was using the same exposure times as before.
So-- since this was without the usual humidity, it couldn't have
been overexposure, right? On Nov 30, 2008, at 2:05 PM, Katharine
