For now only one Local Lab control is possible at a time, but @jdc is currently working on the possibility to add several controls.
In the meantime, if you don’t need to do it on many photos, you can process your image 3 times, the first time from raw to TIFF, and then times from the TIFF you just processed.
OK,
thank you. I will try the TIFF workaorund.
On your example, if you want to enhance color, as it’s in the same tone range, it can be done, even without local lab.
Earlier I was using LocalLab again, and this time I found I could have the markers beyond the photo! I don’t understand why I couldn’t previously - or thought I couldn’t - I think it’s the same version of RT. Anyway, apologies if I was writing rubbish…
Yes, you can have the markers beyond the photo, and “independent (mouse)” allows for some flexibility.
A new RT tool to draw with the mouse the selection shape would make it great.
Hey, here’s a new build of the Local Lab branch.
There’s a very good news for people who like the Local Lab tool: you know can use the tool over several areas (multiple control points).
To use several points, use the newly added “Control Points” slider. For example, leave at position “1”, make some modification of the control point, then to add another control point put the slider to position “2”, make the modification you like. You can go back to control point #1 by putting the slider back to position “1”, and so on.
The tool is described here.
Reminder: this branch, in particular with this new “multiple control points” feature, is highly experimental, there’s no warranty that it will no have bugs or will not crash.
Have fun playing with that!

Any idea if I could install this into a different directory and have both gtk 4.2.1234 and this LL 4.2.953 coexist? I suppose I can fix my vmware install and try it there first, but just thought I’d ask…
I’m not a specialist in this, but I guess you can give a separate destination folder for RT Local Lab during installation. But it will use the same options file, and more importantly the same pp3’s, so be careful not to mix things much. If you plan to use the Local Lab version on some images, it may be better to copy these files in a separate folder.
You can do that, as long as the person who made the LocalLab build used a different cache and options suffix.

Do remember that your PP3 files from the LocalLab build are not compatible with any other branch and will probably not be supported in the future. i.e. treat PP3s from the LocalLab build as temporary files, not something you can return to in a future version of RT (unless in the future you use the same old version you’re using now).

Hi all,
Thanks for the build.
I know it’s a not stable branch, but I just want to point out that I can’t escape from fullscreeen mode (F11).
I had to close RT & reopen to fix it.
Thanks for this. I think I will resist the temptation, since it seems like this is not a tool that’s going to ever get merged.
I didn’t say it won’t get merged, I wrote that the PP3 files are not compatible across branches. The last time locallab was merged with master was on June 18 2016, so all the improvements and additions to master since then are missing from locallab.

“locallab” had the changes from “master” merged into it 3 days ago, and Jacques improved how the local-lab feature works, so what I wrote above mostly does not apply anymore for now if you use SGuyader’s latest build.
Yep, but we just wait for a RT 5 GTK 3 locallab build 
Note : you know I’m kidding, right !
Just to be clear, this version won’t see the pp3’s photos you have treated with other versions. At least; it’s my case.
“locallab” build 92aead8 (version 4.2.1121 but that commit hash tells us much more) is fully capable of reading PP3 files from “master”. You can see this by checking Network Graph · Beep6581/RawTherapee · GitHub
That graph shows that the only changes which went into “master” since the time “master” was last merged into “locallab” were things which do not affect the tools. So as long as your “locallab” build can find the PP3 files which your “master” build created, you can use them.

I looked in old folders. So I was pretty sure this pp3 were “masters”. Maybe I already had a GTK3 test build…
I’ll double check !
I just push “merge with master”, so “locallab” is at the same level as “master”.
There is still a bug
if you use locallab with color-picker (great tool!), you can see the interactions in the selected area
Thanks for the continuing development and builds. Here’s a candid I sneaked earlier today, 1/60 f5.6 iso1250. I used LocalLab on the woman’s head and hands.
Great work! I love this feature, i think it’s very useful. I try your build, I hope that changes will be in next release.
There is a bug in the version 4.2.1121. If i try tu add more than 5 control point RT crash.
There is a debug versione?
