@pauld these are all development builds and I’m not sure that anyone is building them for Mac at the moment.
Thank you!
Thanks to Jacques (@jdc) I can provide another, simpler, way to select most of the skin but excluding Mairi’s red hair, by using the recently introduced “mask” tool. You can see the screenshot below, showing the area affected by CbDL (in grey) and how it is achieved with the mask tool:
With the mask enabled, there’s no need to using excluding spots on the hair, the only excluding spots are for the eyes and mouth.
At first the use of the mask tool was confusing to me, but if I understand correctly, it works by removing some areas form the initial selection:
- when you add the RTspot, it uses the deltaE to “select” the destination pixels (those affected by the filter, here by CbDL), but sometimes such as in this example the deltaE between hair and skin is too small to allow a correct separation
- adding the mask will actually allow you to exclude some pixels from the initial selection, based on L(L), C(C ) or LC(H) equalizer. In this example, drawing a narrow notch in the LC(H) curve at the H corresponding to the hair allows to exclude it quite efficiently from the original selection, without affecting the skin selection.
In fact there is 2 ways for using “mask”
-
“traditionnal”, with “merge” (I call “blend”), image from mask, and original image. in this case you must use, all sliders - blend, radius, chroma mask, gamma mask, slope, and of course 1, 2 or 3 curves L(L), C(C) , LC(H)
-
specific Rawtherapee, in this case, as says above by @sguyader , the mask serves to increase the selection capacity by artificially playing on the deltaE.
The image is not change at all, only “deltaE”.
In this case, you must use : 1 ,2 or 3 curves, radius…
If you use the others sliders, I recommand very very small values, because you change the image - of course , its perhaps the goal - but be carefull.

Why I don’t see this version in “unstable” branch?
@Chawoosh you need to download a specific build, as the local adjustments are not yet in the main version.
If you’re a Windows user, you can download the latest build from here (look for the “RawTherapee_newlocallab_xxxxxxxx…” build.
I’m using Arch linux and rawtherapee repo in a opensuse server.
Two solutions then, as the Arch repo provides only the main version:
-
Compile RT yourself from source, by pulling code from
newlocallab
branch -
Use the
rawtherapee-git
package from the AUR repo, and modify the build script to get the code fromnewlocallab
branch
Below is the part of the build script you need to modify, by just adding the 2 lines in bold font face:
build() {
mkdir -p “$srcdir/rawtherapee-build”
cd $srcdir/rawtherapee
git checkout newlocallab
cd “$srcdir/rawtherapee-build”
cmake …/rawtherapee
-DCMAKE_INSTALL_PREFIX=/usr
-DCMAKE_BUILD_TYPE=Release
make
}
If you need more assistance, feel free to ask.
I’ll wait for this feature in “unstable” version.
If you use pamac
as your Package Manager for downloading/updating packages, it’s really not complicated:
- in
pamac
preferences, just turn onEnable AUR support
in the AUR tab - search
rawtherapee-git
- double-click on the result, it will show you the details
- click on
Build files
from the left side panel - add the 2 lines as highlighted on this screenshot:
- click on
Build
and thenApply
Then pamac will do everything for you (checking/downloading dependencies, configuring, compiling and installing).
If you had a previous version of RT installed, it will remove it, but don’t be afraid, the newlocallab
branch is not far behind the current dev
version, and it is probably ahead of your unstable
build.
And if it doesn’t work for you, simply reinstall your usual unstable
build and it should replace the newlocallab
build.
I’m using aurman, but it’s not important. Git version is installed on my work comp, and don’t updated long time, but unstable was updated every day in a long time. What is important for me - that this feature is in realization.
Hello,
I did try the local adjustment many months ago. The UI was clearly not finished and hard to use. I did not have time to try the many improvemnt from these last months since.
I’ll try to get a try now as it seems to be far more “polished” yet.
I’m curious to see if “carafife” will do something on this subject. He’s doing a great job on darktable & GIMP. It’s a great thing that he’s starting to make some tutoriel for RT in french !

Did the local spot tool make it into 5.8? I’m using it on Arch and don’t see the ‘hand’ editing tab…
It’s not even in the development version, yet. But it will be included soon (hopefully)
Understood - looking forward to it and thanks for your work!
I was so happy to see this tutorial, than I looked myself silly for the RT spot tool. It appears it doesn’t exist in RT? An alternative? Otherwise this great tutorial seems mostly and unfortunately obsolete.
It’s in the development build. You can download it here Release Automated Builds · Beep6581/RawTherapee · GitHub
Note also that my tutorial is quite old and probably obsolete, the “Local lab” tool having evolved a lot since then.
