We just upgraded to Windows 10 and Lightroom Classic 2018 version and I've lost my presets. I am having a very hard time inverting the tone curve (turning negatives into positives). The ends of the linear curve will not budge from their respective corners. Any tips?
You need to select the Point Curve. Makes sure you have the latest LR 7.4 update installed using the Creative Cloud app.
Perfect. Thanks, Todd!
And a hint-
When you have the tone curve inverted-immediately make a Develop Preset, then it will always be just one click on the preset needed.
Also it is now possible to make an 'Inverted' PROFILE in ACR to do a curve invert, but it does not change the problem that many of the sliders still work in reverse in Lightroom.
If you see the sliders in the Tone Curve panel, then click on the button in the lower-right corner to switch to "edit point curve" mode:
It should then look like this:
and you can then grab the ends of the curve and drag them up and down.
Thank you so much for the quick reply! It did the trick!
I've read this and similar discussions, and am now running LR Classic 11.1 but in this version there is no 'edit point curve' mode as in the screenshot in the posts above - have Adobe removed this feature or hidden it?
Isnt this a retrograde step not to have it if it was in earlier versions? Guidance appreacted please!
This has changed in later versions. Click the grey circle.
Thanks...though one click inversion would save time, Adobe!
You can create a Develop preset for this, which would be a one click inversion.
+1 And your Tone inversion preset can include changes to contrast (S-Curve) and the individual color channels if desired.
