Greetings-
Richard K. requested the formula for the GP-2 gold toning formula: (as I
said earlier, this comes from Douglas Nishimura at RIT)-
water 750ml
gold chloride 1% [A] 0.5g
tartaric acid 1.0g
thiourea [B] 5.0g
sodium sulfate (desicated) 15.0g
water to make 1.0 liter
Please note that this formula seemed to be used with microfilms: the source
for the development of this formula was listed as: Henn, R.W., and D.G.
Wiest. "Microscopic Spots in Processed Microfilm: Their Nature and
Prevention." <Photographic Science and Engineering>, Volume 7, number 9,
September-October 1963. Society of Photographic Scientists and Engineers,
Inc. pp 253-261.
And also Henn and Weist."Properties of Gold-Treated Microfilm Images" (same
journal as above) Vol. 10, No. 1, January-February 1966, pp 15-22.
The information sent to me is a total of five pages with *lots* of esoteric
sounding notations about the formula and its use....

Fair enough, but Good Lord! Why so tip-toe defensive?!?
Richard, I would *guess* your reference point with these toners is fairly
traditional in their use and application. And I regret that I cannot send
you with a simple click of a button to a sampling of my images which
utilize these same processes in untraditional ways. However, if you ever
get out of the concrete jungle heading north and have a spare moment, I
would ask you stop at The John Nichols Gallery in Santa Paula - John has a
portfolio of 20 of my images and I believe you might see something which
will surprise you... I am using these processes to achieve exotic
split-tone effects which include a wide range of blues, greens, violets and
reds on a single print....
A decidely *alternate* use of the paper and chemistry - for a decidedly
*alternate* end result....
Hope the paths cross one day!
Best-
Jon Bailey
