This Kallitype was too dark (about 30% overexposed)
steps to rescue
1. bleached 1+100 1 min and fixed again to reduce density, the print was still too dark and soft
2. bleached again 1+50 1 min and toned with thiourea (MT3 with a just small amount of alkali - 50+15+1000ml) to lighten the highlights and upper midtones
3. MT7 Iron Blue 5+5+5+15+5+1000ml 90 secs - resulting hue yellow and green
4. weak solution of ammonia to achieve a cooler tone
Wow this is very beautiful Wolfgang! I often wonder what the masters do when they have a print they've invested their time in that isn't perfect. I try to rescue everything too but I am just learning. I like the way you share this knowledge with us, God bless you!!!
