Basic Adjustments - High contrast turns highlights negative
As in the description.
A landscape scene with bright overcast sky, turning up basic adjustments contrast turns highlights dark.
Using the old brightness/contrast/sat module, turning up contrast does not have the same problem.
Can provide RAW if needed.
Camera is a Nikon D750, full quality RAW if it makes any difference.
