Can sepia toner be used without the bleach?
Will that be equivalent to polysulfide toners?
Sepia toning is a sulfideing of the silver. A bleach is not needed.
The Hypo-Alums, Nelson's Gold Toner, Kodak's and Agfa's
polysulfide are all direct toners; no bleach.
Ann has mentioned the IPI in connection with toning. The IPI,
the Image Permanence Institute at RIT, concerns itself primarily
with microfilm which has some relavance to B&W prints. At
least to read it does.
As for sulfide, they are all for it. The surprise was in how little
it takes. A most minute amount will do. Sodium sulfide at a dilution
of 1:9,999, or .01%, will impart complete protection. There is no
reason not to use sodium sulfide from there perspective other
than matters of S&h of, 55 gallon drums?
As for oder, I detect none from low percentage solutions. Dan
