question
Can this Tannic Acid be use tone cyanotype prints? If so, what color does it turn the print?
Tannic Acid does in fact tone cyanotype prints. If toned straight in a bath of tannic acid it will darken the print give it more of a violet/purple tone. There are a variety of toning combinations that use this, and I recommend the Book of Alternative Processes by Christopher James if you're interesting in more.
