Yes, John, Steiner did use a bleach process for making his highlights brilliant while still maintaining deep, rich shadows. He used a highly dilute solution of iodine and water for the bleach followed, of course, by fixing. I believe the iodine solution was tincture of iodine from you local pharmacy diluted by adding only a few CCs of iodine to a liter of water. Maybe only 2 or 3 CCs per liter. It will take a little experimentation to determine the exact dilution that works with whichever paper you elect to use.(posted 8328 days ago)
