From what I have read, exposing a cyano to direct sunlight
causes the prussian blue to convert to prussian white.
If the "faded" print is left in a cool dark place it will slowly
recover the image as the prussian white converts back to prussian
blue. I have no direct experience with this, as I keep
cyano prints out of direct sun.
