Carol and list,
I and several other people regularly "spot" cyanotype with watercolor
pencils. I have also "spotted" VDB the same way. I see nothing wrong with
doing this. Afterall, people use Spotone on silver-gel prints
all the time. I also confess to using a graphite pencil on platinum.
If someone figures out how to "spot" a daguerreotype I would be
grateful for the information. ;-)
