That is a great thread however, I was actually referring to a thread that discussed the relationship between the Fine contrast slider and the highlights, midtones, and shadows sliders. I didn’t see anything related to that in that link you just shared.
Here is the thread on this subject to which I was referring.
I also believe there may have been a second thread on the subject that may have gone into even more detail on the Fine contrast sliders, if I recall correctly.
