Bonjour Jacques,
Is there a way to darken the Control Point area to 100% black?
Sometimes I use the Control Points to darken certain areas.
Merci
I have modified the algorithm. Now with lightness < -90 to -100, dark is increase. But we cannot completely dark to zero…
I solved a bug in “contrast” that caused a crash in some cases. 
Sounds good, Jacques!
Passez une bonne journée!
Merci
Jacques
I added in “Preferences - Performance and Quality” a topic “Local Adjustment” - “Quality Method”.
This allows you to change the default choice - which is “enhanced + chroma denoise”. Indeed the usual pp3 files are here inoperative.
You can so if your images are without noise, use a faster algorithm. Of course the choice in the menu “Locallab” - “Global Quality” is always possible.
I updated, Rawpedia
Very nice, Jacques. Thanks!
The “Color & Light” change works well.
I’m looking forward to try “Local Adjustment” and “Quality Method”.

Thank you for this build
I have not these warning…I’ll try to correct them !
Jacques
Jacques,
A circle to indicate the area affected by Local Lab would be nice to visualize the area. Sometimes what I do to work around this, is that I set Lightness to -100%, that way I can see exactly what the affected area is. Perhaps a temporary check mark to turn visualization on/off would be great.
I’m using

https://drive.google.com/drive/folders/0B2q9OrgyDEfPS2FpdDAtMVI1RG8
It is working fine here.
Thanks!
@dngimage
You can go to “Preferences / General / Local adjustements”
And checked the box “Show spot delimiters” .
It’s not “perfect”, Elipse with Cairo Graph tool does not work…I replace by multiple Béziers curves
Jacques
@jdc,
“Show spot delimiters” helps!
Thanks!
@jdc,
Using Local Lab, if you activate Tone Mapping and move the Strength slider around, RT Local Lab will crash.
Also, Sharpening doesn’t seem to have too much strength.

Thanks!

I tried to fix this crash (I just push a change), which happens randomly…in some cases.
I have done some changes (little) to OMP and also round interger…For me now, it does not crash but I don’t know why
Here’s locallab_dev running on MacOSX.

In case you can’t tell I have the “spot” on the chicken’s face, with increase in contrast and colorifics.

Jacques and Ingo,
The bug is gone. No more crashes. Thanks! 
But Sharpening doesn’t seem to work, it doesn’t do anything.
And yet it works. Of course this depends on the position of the spot, the value of “scope” and what one wants to do. I deliberately chose low settings.
Try for example on the following image, for me on this picture everything works fine
http://rawtherapee.com/shared/test_images/amsterdam.pef
Nevertheless I just changed (I just push) a few settings to increase the possibilities, especially “radius”, but watch out for the risks of artefacts
