Re: Paul L. Anderson
LOLOL I never thought to check! My husband's name is Tom and when we lived
in Minneapolis there were 64 Tom Andersons in the phonebook, not to mention
how many Chris Andersons there are. That's why I go by Christina Z.
Anderson (operative letter "Z") because that narrows the playing field a
tad.

As Paul Anderson authored a number of books on Pictorial Photography (The
Technique of Pictorial Photography, Photography, The Fine Art of
Photography, Pictorial Photography, Its Principles and Practices, and
Pictorial Landscape Photography) and was quite the gum printer, I went
online and did a search and found that the Center for Creative
Photography in AZ has a TON of his alt work. Those of you who live there
can stop in and see it. Here are the holdings:
http://www.creativephotography.org/collection/webbooks/anderson.pdf
It looks like his first book was in 1913, and I am pleased to have one of
his early articles before that time on multiple gum printing, from
American Photography 1912. Also his 1913-14 articles in the same
magazine, a 10 chapter Gum-Pigment Process. Also his articles from 1935.
The 1913 article expounds upon the dreaded stain test which he gets, as
he says, from Koester's Der Gummidruck book (1904).
It is also interesting to see that in 1912 he was using a gum arabic mix
that contained arrowroot or dextrine in these proportions:
12 oz water
2200 grains gum
270 grains arrowroot or white dextrine
mercury bichloride 15grains
But by 1913 he was suggesting not to add anything, though the starch
would cut down on the gloss in the shadows. His formula by then for gum
Arabic was:
1 lb gum
25 oz. water
which he calls a 60% solution (actually 64% by weight but when mixed it
would be more like a 50% solution as a rough guess, as I found that 65g
of gum "packs down" to approx 25ml volume when mixed in water by a VERY
rough calculation so don't take my word on this one; but still, this is a
much thicker gum than we mix today and seems to follow the Germans with
their 60% recommendations).
He varies the ratio of gum to sensitizer according to pigment used
according to the stain test, too long to go into, but his ranges are as
high as 4 gum to 1 sensitizer (permanent blue) and as watery as 2 gum to
5 sensitizer for burnt sienna. In the 1912 article he was not varying his
ratio much, but used 1:1 or 1:1.125.
Enough now, back to writing.
