    Camera Raw Default Tone Curve Function / Coordinates

    [ENH] KelSolaar Level 1



      I would like to know where I can find the function / coordinates for the Lightroom / ACR default tone curve that is applied to any image.

      I think it's the red one in that image, or it's very very close:


      I want to generate a lookup table to match it's effect. For now I plotted something that is very very close but I lack precision at the bottom of my curve.
