Hi All, i have been doing some some Kallitype prints lately and everything looks fine until the bleaching in the fixer pretty much ruins it for me. I have tried printing darker etc, but the whites just bleach out to a point I don't find appealing. Rather than give up I was wanting to try some toning first before fixing. From the B&S instruction sheet, to 1 ltr of citric I add 5ml of gold or pd/pt. I have palladium and my questions is how long does the toner last? 5ml is a lot to blow in one go. Thanks for your time.
