What are these sliders in the tone curve for?

Does anyone actually use these? Please explain how they can be used.

Yep, I use those sliders in the tone curve option shown in LR. I rarely move the middle slider, but moving the slider on the right, to the right restricts the tonal values affected when increasing/decreasing the “highlights”. Same concept for the slider on the left for the “Shadows”. The cool thing is once the slider has been moved and a tone curve adjustment has been made, moving the slider again shows a change in the amount of change applied to the image.

I do wish Adobe would be more consistent in their names for the tonal ranges. In the Basic panel they correspond to Whites / Highlights / Shadows / Blacks even though they don’t represent the exact same tonal ranges. At Least the order would make sense.


That makes sense, thanks Keith!
