Hi all, I've started moving from Cyanotypes to Van Dykes, as I've been wanting more neutral prints. I made a first batch a few days ago to check exposure times and single vs double coating (I'd read that double coating was recommended for shadow values, and that was what I found). Today, I did another batch and tried gold toning. I'm using the gold toning kit from B&S (.2% Gold Chloride solution, 2% Ammonium Thiocyanate solution). The instructions say to mix 1000ml water with 50ml each solution. I made a 500ml batch instead (so 25ml each). I rinsed the prints, then put them in the toning bath. As the title suggests, I saw very little color change in the prints; it seems like the highlights turned a neutral grey, but the shadows didn't seem to tone at all. For the last print, I added some more gold chloride, and toned for much longer (10 min or so), but still saw the same thing - highlights toning while shadows staying the same. What's the issue here? The few examples of gold toned Van Dykes I've seen online have been very neutral overall, not like my prints. Am I mixing the toner wrong? Would I have better luck with a different formula (I've seen at least two other ones - a thiourea + tartaric acid formula and a citric acid formula)? Longer toning? Stronger concentrations? Any help is appreciated!
