I am trying to do an accurate color adjustment using the "Threshold" darkest and lightest sample point, new layer-50% grey "Difference" mode, then back to "Threshold"
to find grey point. Having marked these points, I go to "Curves" and select my points with the appropriate eye dropper tool.
This technique worked flawlessly in
