..in my quest to get my weak negatives "denser' I also tried selenium
toning (Kodak), reported to give a half to one stop density increase, my
limited experiments on this showed no effects after selenium toning. I do
have a report about density increase by using a sepia toner, but I did not
try that, I did try mercury int..oh I should not elaborate on
that...;-)..(btw I work in a lab....). On the pyro negs: in my answer to
Jack I quote a post which claims that you can go through repeated cycles
of bleach/pyro developing for density increase, but I did not try that
myself
