Hi John,
I haven't plowed thru all emails to see if this has been answered, but
what he does as one method, not the "Zimmerman" method technically, is he
uses a non pigmented sensitized layer of gum and prints the first layer to
get the image and tones in clear gum. Then he takes plain watercolor and
watercolors the different parts as he sees fit. Then when that is dry he
coats another coat of non-pigmented gum/sensitizer in the ratio of 1 gum: 4
sensitizer, and exposes again. Essentially two clear layers of gum arabic
sensitized with pot bi, and a watercolor layer inbetween, kind of paint by
number you know? Anyway, I'm trying that this week to see if there are
possibilities.
It's probably easier to go online and check out the Zimmerman Photo
Miniature article on B+S website. It takes a while to read thru (and Dick,
where is the last page or so??) but is well worth it. I don't think I will
attempt the high ratio of sensitizer he does with traditional gum, because
if Demachy is correct back in 1898, he says if you use too much sensitizer
in your pigment mix, it'll water it down and cause staining. But aside from
all these details to try this week, I want to go thru the D. Smith catalog
and see which pigments are labeled staining and which are not, and see how
that all relates. OHHHH, so much to test, so little time....
Chris
