Hello,
Chemical question: The basic dageurrotype process involves making silver
halides on a silver plate, exposing, and then developing with fumes of
mercury, which presumably makes mercury-silver amalgam, fixing, and then
toning.
Why couldn't a standard developer, such as Metol or Pyro, be used instead?
Does it attack the plate, not develop a sufficiently strong image, or is
it just a method that was never employed before daguerrotypes fell from
favor?
