Some new
I deeply modified the information on the use of masks.
On the principle not change of algorithms, otherwise to ensure that each module allows the multiple use of masks in normal mode or in reverse (I found some bugs…and solved them)
You can watch the documentation (always in french) on Wikipedia, and I add some Tooltip (near masks)
https://rawpedia.rawtherapee.com/Local_Adjustments/fr#Algorithme_compl.C3.A9mentaire_-_Mask
Concretely you can for a RT-spot use several masks in normal mode or in inverse, with or whithout duplicate RT-spot
The masks that allow use (by activating the expander of the tool, but without using the tool) are marked with a “+”
The order of the masks is identified by a number.
To add a mask in “inverse”, you must enable a tool (expander), and use this tool with a very small value (ex Exposure 0.01),for example with this choice and the use of the curve (C = f (C)) you can desaturate the background
I added the possibility to use a “Laplacian” of 2 ways, either direct (reduces the artifacts and increases the local contrast), or with “solve PDE” which makes it possible to reduce the differences of luminance of the mask

Others news : October 24th 2019
I am obliged to edit my previous message because PIXLS.US does not allow to put more than 3 messages without another intervention
I brought a series of new modifications, those that come from the work of Alberto Griggio(ART), those from me, and those on the masks
From Alberto (thanks to him)
- Tone Equalizer
- Film Grain
- Log version for Guided Filter
- Threshold for Denoise DCT
From me:
- Threshold slider for “Wavelet Local Contrast”
- Use FFTW in some cases instead of Gaussian Blur
- Fixed bug, bad behavior and crash in some cases
On masks:
a) “Contrast curve mask” for all masks (mask 1 to mask 7)
b) “Local contrast wavelet curve mask” with “slider threshold” for mask 1 and mask 7
c) “Shadows mask” for mask 7
d) “Highlight mask” for mask 1
e) “Dynamic Range compression” for mask 4
Of course, I can extend these features (b, c, d, e) to all masks
Possibility for “normal” masks (not for inverse) to take into account the deltaE of the original image to differentiate the action on the mask (menu settings)
Possibility of “short circuit” mask curves L(L) and L(H) (menu settings):
- this allows to work on the possible combinations of the work in progress and the original image (via a mask)
- usable for mask : 2, 3, 4, 6 and 7
- all the treatments mentioned above (a to e), and gamma - slope, and Chroma, can be used
Possibilty to change Luminance background Mask (menu settings)
Reminder:
1)you can combine the masks with or without creating a new RT-spot, in “normal” or “inverse” mode
2) you can use “Local adjustments” in full-frame mode (RT-spot beyond the boundaries of the image), with Scope, etc. today manually, Pierre Cabrera @Pandagrapher is, I think, working on this topic to make it more user-friendly

Another new !
I brought a series of new features (I hope no bugs 
):
-
Recursives references
** note that this addition has resulted in a significant malfunction of virtually all “locallab”, due to 4 lines of code in improccoordinator.cc – “it’s the story of the cat biting its tail”, since november 13th this issue is solved, thanks to @arturoisilvia
** this functionnality (in Settings) allows the 4 references to calculate deltaE (hue, chroma, luma, sobel) to be update after each module, and each new spot
-
Tone equalizer
** I add “TRC” (Tone Response Curve) : an other way to play with Shadows and Highlight
-
Mask deltaE images
** As you know masks (except for Retinex and tone-mapping) are generate “before” calculation of each module. This mean that the variations due to the mask are taken into account for “scope” but after calculation.
** This option in “settings” allows to take into account deltaE to generate mask
** enabled with a checkbox, and set with slider “Scope Mask deltaE image”
In module “Color and Light”
4) “rgb tone curves” with 4 choice :" standard, weighted standard, luminance, Film Like", with a checbox “Special use of RGB curves” - this choice disable completely “Scope”
-
Merge file with 3 actives choices :
** Short curves ‘L’ mask (as said before)
** Original image : the current image is merge with “original” (before all “locallab” threatment)
** Previous Spot : the current image is merge with “Previous Spot”
** you can use for merge : normal, substract, difference, multiply, addition, divide, soft light, hard light, overlay, screen, darken only, lighten only, exclusion
** you can set : opacity and contrast theshold
-
For mask 7 (Color and Light) and mask 1 (Smooth Blur and Denoise), I have added a new type of mask : “Structure mask” to differentiate the action between the contrasting reliefs and the flat areas
- a slider “Structure mask” allow to choice the intensity
- a checkbox “Structure mask as tool”, allow either to use “Structure mask” to generate a mask with the same manner as curves LCH or either to use “structure” to modify mask generate by curves LCH
- of course, if need, I can equip each mask with this feature
