Thank you very much. I think I will stick with the
self-made sodium citrate way, because I had searched
for oxalic acid once (for 1% precoat cyanotype in
order to decrease contrast - then I rearranged my
curve setting and got near-perfect cyanotypes without
the need of acid coat using the traditional formula +
a simple modification of adding 2-3 drops of Ilfotol
to 20ml of sensitizer. I guess I will not have
"perfect" cyanotypes due to the shadows compression /
contrast decrease when the print is dry) and couldn't
find in my area unfortunately. (Any tips? In what
industry / area is oxalic acid used most?)
