I want to work on the highlight region only and keep the blacks super black.
Ian I want a very strong bleach effect as I need to bump up the highlights dramatically as I am making solarized prints where the highlights are too muddy for my taste .
any suggestions on the dilution ratios that would work well I am using Ferri/Bromide currently at 32grams each to 12 litres of water.?
I do not want to reach the shadows.
