Cyanotype toning
By Susan

Works great with cyanotypes. I use 10 grams to 2 liters of lukewarm water and tone the photos for about 30 minutes for a deep rich color. Mixes well.

Used this as an alternative to tea and coffee to tone my cyanotypes. Works great, without staining the paper. Gives a reddish brown color, if toned without sodium carbonate bleach first. With sodium carbonate bleach step, more of a straight brown (but shadow and highlight details disappear...not to my liking)

question
Can this Tannic Acid be use tone cyanotype prints? If so, what color does it turn the print?
I tried it once using washing soda to bleach the print prior to toning. The color came out medium-to-light brown and the paper itself stained tan, so the contrast was much lower than the original cyanotype. It works, but it may take some experimenting to get it right. I think I over-bleached the print; if some of the original blue had remained then the final toned print would have been more contrasty.
