KRST can be used to tone VDB if used carefully. I can't recall the name of the photographer who turned me on to this method but if the KRST is used in extremely dilute amounts VDBs and kallitypes can be toned successfully, before or after fixing. It can also be used in combination with gold toner to make beautiful tones. It's tricky but can be done. The key is to experiment. Start with 10 grams of KRST to 1 liter of water. A more dilute solution maybe called for. Some reduction may occur if so dilute further and try again. One shot toning using about 30 or 40 ml per 8x10 sized paper. Don Bryant
