Change temperature for different part of the curve

[fabsim08]

Hi everybody,

I wanted to know if it's possible to change kelvin value but juste for a part of the curve with lightroom. For exemple to give some warm tone to the hightlight.

Or to give some cool effect but just for the shadows.

For those who know this kind of software, it is like a grading tool for vidéo (Da vinci resolve for exemple) with the famous wheels of lift/gamma/gain. Where is it possible to give some temperature or tint but only in a part of the curve.

Thx For answer

You can do this using the split toning control. This is found (I am assuming you are really running the cloud-based Lightroom CC and not the desktop based Lightroom Classic) in the effects section of the slider tools by pressing on the icon next to effects that looks like a black and a white rectangle on top of each other.

Thx for answer

I think I'am using the desktop based Lightroom Classic,  because I haven't this kind of thing in my panel effect...

If using Lr CC try clicking on the button with red border in below screenshot. If using Lr Classic then see lower screenshot

Yep thx Ian. My version is the classic version.

It's close what i'm searching. But I don't understand one thing. When you click on the small colored square you open a window. In this window you can choose the limit of your highlight (or shadow ) and the color tone of it. You can adjust the saturation also in the first page.

But on the line with an ''S'' you can go from 0 to 100% of the signal. But why the cursor of the hightlight is beginning on the 0% (like the shadows)? It will be better to be able to choose the limit of the highlight from 100% no? For example, how it is possible to choose the top 5% of the curve to apply correction?

Thx again.

Unfortunately you can’t do it that precise. For what you want you need Photoshop or something similar.

Ok thk to everybody for your help

I just thought of a hack to accomplish this. In Classic, add a local adjustment either a gradient or a brush. With the gradient position it so that it affects the entire image or if you use the brush, just brush the entire image. Now dial in that the local adjustment modifies your white balance how you want it. Enable the luminance Range Mask at the bottom of the selective edit section. Drag the range sliders to the part of the curve that you want to modify. Check with the "Show Luminance Mask" checkbox whether you are affecting the parts of the image you want to affect.
