BLUE IMAGES WITH AN INDISTINGUISHABLE STATUS BETWEEN PAINTING AND PHOTOGRAPHY CYANOGRAPHY, AN ANCIENT TECHNIQUE THAT HAS BECOME AN ALTERNATIVE ART FOR The formula was perfected in 1842 by a brilliant scientist, John Herschel: A - ferric ammonium citrate B - potassium ferricyanide These chemicals are each mixed with distilled water (A at 20% and B at 8%) then the 2 solutions are combined in equal parts to create a photosensitive emulsion, i.e. one that reacts to light. The emulsion is greenish-yellow and turns blue after exposure to ultraviolet [...]
