Thank you 
But, sorry, in my “optimization”, I have forgoten to take into account the slider “Chroma detail (DCT)” (it was good in previous version not optimized)
I just push a new build “2c5e992”
Thank you
Jacques
@jdc Jacques, there’s a possible bug in the latest build (just compiled from commit 2c5e992…). When I set several RTspots, the on/off state of the modules is not reset when switching between spots.
For example, if I turn “Color and light” on for RTspot #1, when I create a new RTspot #2 it shows “Color and light” already “on”. Of course the sliders are at their default values, but it’s confusing when you have several spots with different modules activated.

Cela a toujours été comme cela (du moins depuis que j’ai installé cette option) : l’activation “on / off” de chaque module “color and light”, “retinex”, “denoise”, etc. est globale pour tous les RT-spots…et j’ai du l’écrire quelque part
Bien sûr il est possible de changer cela, mais cela va complexifier le système
Jacques
Je viens de trouver où c’est écrit ==> dans Rawpedia
"J’ai ajouté, pour faciliter l’utilisation et éviter les menus trop longs en mode écran, une interface GUI similaire à celle de Wavelet, avec des “expanders”. Vous avez ainsi la possibilité pour chaque famille d’action (color and light, Blur, Retinex, etc.):
_faire apparaître ou non le détail des commandes : curseurs, méthodes, courbes,.._
_ activer ou non l’ensemble des fonctions de la famille d’action._
Attention, le choix - 2 - active ou annule l’ensemble des RT-spot ( spot de contrôle); il est théoriquement possible d’associer cette possibilité à chaque RT-spot, mais quel intérêt ? "
I didn’t realize that.
Anyways, I was using the Local Lab on very big files (stitched panorama in 16-bit TIFF, 22131x3611 pixels!) and I had to use RTspots one by one, saving the result at each step, because it needed too much memory and crashed too often (particularly in “Denoise”). So I did get confused as I never had too many RTspots at the same time.
I will look but it will be probably difficult with some incompatibilities
due to management of expanders.
Jacques
Don’t worry Jacques. Leave it as it is.
Sebastien
I will look tomorrow, I think it will be possible to enabled/disabled each “part” for each Rt-spot, but I think we will loose the posoobilities of expanders “memory open or close - expand or not, etc” that are stored in “option” and then not updatable in real time.
Rq : now the system works very bad (expanders) and I don’t know why (this as not due to locallab, it is a general problem with expanders).
Jacques
Thanks Jacques! I will try later!

I just push a new update for newlocallab 42d0f55
It will probably be the last of 2017 …
I will be away from my home from Saturday 23 December until 3 January 2018. Meanwhile Internet connections will be problematic
This update is important because it significantly improves the shape detection algorithm by reducing artifacts - often due to the presence of a little chrominance noise that is often almost invisible
By default, “quality method” is set to “enhanced” instead of “enhanced + chroma denoise”. This without quality reduction will reduce processing times (except for Denoise).
In difficult cases you can choose “enhance + chroma denoise”, or activate the noise reduction in “denoise” (chroma)
I recommend cleaning the cache (pp3 and mip), to have an update of the default settings.
I update Rawpedia (in french)

Hello
I just push a change 17999b7, with numerous improvment to “local denoise”.
Now (for me) local denoise is good…
But my computer is in bad health… very very bad, probably I will change it…next year
Happy new year

Hi,
I am kind of a lurker on this thread, but I silently do try local lab again and again. At this point I wanted to say a big thank you to @jdc for all the work and to @gaaned92 for the builds and to @sguyader for all the checking and feedback and to all the others i might have missed. 
In a later version of local lab I would also find it useful to have a rectangular point additionally to the elllipitical we have right now, and also a gradient.
With the last commit 63073b4, you can choose between an eliptical area, and a rectangle area for “normal” mode.

Nice addition Jacques.
@sguyader
In theory, if the GUI allowed to draw a Bézier curve (I do not know how to do with GUI), between each of the 4 delimiters, it would be relatively easy to add a method in addition: “elipse”, “rectangle”, “free”.
With “free” one would have almost the equivalent of a clipping / cutting with the mouse (I do not know if it is the good term) that some people claim (not quite because it is essential to keep a curve homothetically possible).
