Hi all,
I'm brand new to the list and hopeful someone out there can give me a
little advise. I'm trying to tone cyanotypes black. The formula I have calls
for a sodium carbonate bleaching then "redevelopment" in gallic acid and a
touch of pyro. This gives the print a nice color but no DMax. What was solid,
dense blue before toning becomes no darker than zone 5 afterward. Does anyone
have a formula that works and yet allows for a good dmax. Thanks
Mike
