I'm fogging my cyanotype paper. An example is attached. Note the fogging that seems to follow my brushing. This was after a day of drying in a somewhat humid environment (the cabinet under my bathroom sink.) Traditional cyanotype with dichromate added, Arches Platine paper, two coats. My only thoughts at this point are possible contamination from the brush or from letting the solution sit an hour between coats. Any ideas or suggestions? Thanks!
