The other night I tried the recently mentioned cyanotype-like toner on some silver
prints (polycontrast RCIII) and produced a very nice blue-gray color. Does anyone
know if this is archival (both the color and to the print)? Interestingly, the blue
tone can be removed with a solution of sodium bicarbonate recovering the original
black and white image but with a slightly warmer apperance.
