I am scanning negatives using DSLR. Today I updated Lightroom Classic to version 15.0.1 and cannot now invert Tone Curve as I used to do earlier. In Tone Curve panel I am not able to drag left bottom point to upper corner and same with upper right corner point to bottom. I am using Macbook Pro with macOS 15.6.1. Am I doing something wrong?

Correct answer Ian Lyons

You need to switch to the Point Curve as shown on attached screenshot

Hi @Samil_9805, welcome to the community!
I tried reproducing this on my end but haven’t had any luck. Can you share a screen recording of the issue?

As a first step, could you try resetting your preferences and see if that helps? You can follow the steps in this guide:

Hi @Aleke ,

I resetted preferences and still no change. Attached screen shot of Tone Curve module which I took before resetting preferences. It is aftere reset the same. Module does not offer any possibility to select between Region Curve / Point Curve. No icons for that.

Thanks a lot,

Samil
