On the topic of Lightroom sliders

Ultimately, we can probably ask for something along these lines:

  1. Can we generate a luminosity mask for use from within RT?
  2. Can we have that mask applied in a new module that allows us to modify tones?
  3. Can we have control over which tones of the mask get used?

I could see three sliders being used here, maybe four.

  1. Highlights tone control to pull them brighter/darker
  2. Shadows tone control to pull them brighter/darker
  3. A slider to control the crossover point of the luminosity mask.
    a. Optionally, two sliders - one for crossover point, the other for tonal “width” that the mask is applied to.
