Re: old sepia toner

I have a comparison chart for sulfide toners at:

http://silvergrain.org/Photo-Tech/toners.html#t004

If the solution was pale yellow color and toning required bleaching
before toning, it's probably what's listed "sepia" in the chart. If
the solution was more like orange brown and the process did not
require bleaching, it's probably polysulfide toner. But the latter is
usually called brown toner, not sepia toner.
