Hello All,
I plan to give a try to the PMK-pyro developer that uses sodium
bisulfite as preservative. I would soup the dev of raw chemicals. The
thing is that I don't have sodium bisulfite, but have potassium
metabisulfite. Many places I've read that sodium bisulfite can be
sibstituted for sodium metabisulfite weight for weight, but what about
potassium? Does anyone know anything about it? Can I use what I have,
and if so, what is the ratio?
Thanks in advance!
Krisztian
