Hello
I fixed a major bug, which caused a crash when you “delete” a spot.
I made 2 improvements

Several CAM16 spot spots were used to highlight Horse.
Some light blurring spots were added to the street and background, except the red street signs, in order to tone down the non-foreground textures.
Finally, Blue Horse was unblued with a Color Appearance CAM16 spot.

Overall boosts in lightness and contrast; a spot with CAM16 lightness set all the way down to black out the green tarp.
BTW @jdc I noticed Contrast Threshold (J & Q)
will clip from black to white if you raise it too high with a sufficiently high Contrast level.
PS @jdc Sorry I jumped the gun on your whole “one week interval” idea…
PPS @ jdc Overall these CAM tools seem to work at a better dynamic range than other of the CAM16 implementations. I could easily process an entire photo using mostly only the local CAM16 spots.
Hello Richard,
I am pleased that you are using my picture here. But I still haven’t quite understood what you want to show with it. I’m already very curious.

We are testing an experimental change in RawTherapee in this thread, of which @jdc is the author.
Hello everyone and many thanks for your contributions.
@HIRAM @priort
With the time difference, it’s a bit difficult to communicate. Let me remind you of the origin of this post
"The aim of this challenge is twofold: a) to allow you to familiarise yourself with Cam16 and the tools that have been integrated into the Local Adjustments “Color appearance (CAM16 & JzCzHz)” module. b) to validate the changes before merging into “dev".
I’ve chosen these 5 images because they all present a specific difficult character: high DR, noise, deep shadows, high contrast between background and center of the image, colorimetry, etc.
Of course they’re well known, and that’s one of the reasons we chose them.
I’d like to create a collective Feedback Report so that users have several ways of processing an image at their disposal. I don’t yet know what form this will take, but it presupposes that I include in a document :
In order to allow the same amount of time to work on each image, I suggested processing one per week, which would also make it easier for me to provide feedback.
But that doesn’t matter, and as Pierre de Coubertin, who organized the first modern Olympic Games, would say : “L’essentiel est de participer”.
If you can this week on the first image (IMG_0080.CR2) that would be preferable, but I’d rather have a messy participation than no participation.
Thank you again.
Jacques
very well done!

See Rawpedia:

Yes, without using “Log encoding” type functions, we easily arrive at a Dynamic Range of more than 20Ev, which is more than sufficient in 99% of cases (Maximum Cameras about 15Ev).

Hello all
I just added in Cam16, in
On the test image - TIF at 25Ev - with Cam16 Image Adjustments - Saturation = 73, we arrive at DR = 23Ev.

Hello Richard,
I see, everything’s fine. I’m honored if the example can be helpful.
Jacques I’m going to try the latest version to see if I still see this issue but I am having trouble it seems in Windows with the version I am using. I add the spot and confirm that I enable it and then add the tool but none of the sliders or settings work initially. I check the delta E mask for the spot and nothing is masked. After a few attempts to change through basic standard advanced at some point things kick in… I am going to try the latest version and also do this systematically so that I can describe the problem if there is one… I’m just throwing it out there incase anyone else had some finicky interaction with the spot and this tool…
