Lightroom Classic: Improve tone curve to better match Photoshop

Lightroom Classic's tone curve could be improved considerably if it were just a little more like Photoshop's tone curve:

Display the red, green, and blue channel curves along with the RGB curve when RGB is selected in the Point Curve mode. It is annoying not being able to see all the curves together.

Provide an Auto button that at the very least applies Enhance Per Channel Contrast with a Snap Neutral Midtones option. Enhance per channel contrast can be done manually, but it would be so much more useful if it were automated - then there is the possibility of adding it to a preset, which cannot be done with a manual adjustment since every image is different.

Not too much to ask for, so please consider.

Great idea that would be very helpful when adjusting certain image file types. I also suggest that Black and White point sliders be added at the bottom of the Tone Curve Histogram same as in PS. Often when adjusting these they are pulled off of their 0% and 100% horizontal axis, which limits the clipping point in the Basic panel.

This reply was created from a merged topic originally titled we need Point Curve feature parity between ACR & Lightroom Classic and a better U....

ACR's UI for point curve manipulation is dramatically better than Lightroom Classic's:
  • in ACR, clicking a point doesn't accidentally move the point
  • in ACR, you can select a point by clicking it, and it remains selected
  • in ACR, selected points can be manipulated with the keyboard
  • in ACR, you can use Control-Tab to move between selected points
  • in ACR, once a point is selected you can edit it numerically by entering specific In/Out values
Additionally, the tone curve in LR doesn't even use the full width/height of the panel, which makes it terribly small on large displays!

I strongly disagree with the moderator's decision to merge my Idea with the above Photoshop-related one (which is also good).

I am NOT asking for Photoshop's curve.

I AM asking for ACR's curve, which is much more achievable given that Lightroom and ACR share the same underlying processing engine.

Since ACR is a part of Photoshop you've added another viewpoint with suggestions for Adobe to consider when (and if) they improve the Tone Curve panel inside Lightroom. IMHO your suggestions fit well here.
