Many thanks, @s7habo ! Not only did you answer my request, but also used Colour primaries, which I am a great fan of!

@s7habo You donāt need to create a snapshot to compare two duplicates. If you are on one duplicate, click and hold the thumbnail of the second duplicate and you will see it.

Just one day into the new year, and you are on it again - new and unbeatable personal record! Bodes well for us in the audience. 
Thanks anyhow!

Thank you, Boris, for your excellent videos, they are not only informative and very well made, they are also nice and friendly, civilized, a joy to watch. I am afraid that this is becoming a rare and precious good, so, please, make more, when possible.
Be well, a happy - as possible - new year to everyone here!

Dear Boris,
thanks again for providing such brillant editing moments.
Currently I am struggling on Episode 82.
my histogram looks constantly different to yours when doing the same thingsā¦
Hereās your teal and orang 2019
and that is mine with current master 5.1.0-27-g6063a61511 (also tried 5.0.0) and it is not about filmic vs sigmoid, I have tried thatā¦
I donāt mind the saturation, but pls have a look at the histogram and I have checked the first color calibration many times. Manly I do not get the exact complementary colors but more like ā4 oāclockā
Hereās my xmp

could you do me a favour @s7habo and have a look you still get the same histogram from your that Episode but now with 5.0.0 or latest master or you get more something like me (than I wonder why and where to dig)
TNX
EDIT1:
it is likely something in my darktablerc. For some other investigations I moved away darktablerc and tested this thingie here quickly, just with another photo and get the complementary colors right awayā¦ strange
You have done everything correctly. The display in the Vectroscope is set to RYB color space for you and to CIELUV color space for me.
You can change the color space here:
When I have changed to RYB, Vectroscope looks exactly like yours:
You can read about these settings here:

thank you very much Boris. I was starring at my darktablerc already with diff (yet I do have that other issue but not related to here)

Happy new year, Boris!
Great Video to start the yearā¦ I again learned quite something watching it.
Thx for your efforts and showcases, that help a lot to better master darktableā¦
Your contrast preset is pretty nice. I think I need to rewatch your video on the āDiffuse and Sharpenā module several time to better understand how you configure your presets here ā¦ ā¦

Hi Boris, Iāve recently switched from Lightroom to darktable (and from iMac to a Linux PCā¤ļø) and your channel has been fundamental in this process: thank you very very much.
I couldnāt find any videos in your channel about noise reduction, do you have any suggestions on this topic?
In my previous workflow I was relying on DxO PureRAW and Lightroomās AI denoise for high iso shots, so now Iām struggling a little dealing with noise in darktableā¦ and I really donāt want to setup a VM just to use PureRAW.

Paolo, there arenāt many videoās to my knowledge about the noise reduction in DTā¦ THe creator of the denoise profiled module has a YT channelā¦ He has some detailed videos about handling noise in DTā¦even the one he does for a very old version ie 2.6 still demonstrates ways to handle noise that can be used in DTā¦Basically you have astrodenoise (previouly was the non-local means module I believe) which I sometimes add into handle the fine salt and pepper type noise, denoise profiled, surface blur which is the old bilateral denoiseā¦, you have raw denoise and profiled denoise and finally the contrast eq can be used to work on noiseā¦ All of these methods are described in some detail by rawfinerā¦

Keep in mind the UI will look a little different as this is an old video but the actual methods can all still be used as demonstrated for the most partā¦
You can find a few other videos but if I recall from watching the ones that I have there are often some errors or omissions in the coverage of the materialā¦

Hi Paulo,
Rawfinerās videos are great as a developer.
Thereās also these channels you can search for videos on denoising or noise reduction:
https://m.youtube.com/@audio2u
https://m.youtube.com/@JasonPolakPhotography
Iām not sure, though, whether these contain any errors. I think I found them useful
Cheers

Tomas also summarized quite a few tidbits and tips about denoisingā¦much of it is now older but likely there could be some hints in the various suggestions around blending modes etc that might still be worth exploring if someone wants to go nuclear

Thanks a lot, all your suggestions have been really useful!
I like darktable as much as Iāve always hated Lightroom, but establishing a new workflow with it is giving me quite a headache!
Thereās so many ways to do similar thingsā¦ and Iām still deciding between Filmic and Sigmoid as a default!

Hello Boris,
thank you for your great videos and if you donāt mind, happy new year.
I like to work with Darktable under Linux and try to develop pictures of pets with it, to put them better in scene.
When I look at other videos on YouTube on the subject, itās always about Photoshop, of course and unfortunately. That would be the same as Gimp.
Now my question, you write that you work with Darktable every day, do you also use Gimp? Since people always talk about the layers that are available in Gimp or PS, Iām surprised that you donāt seem to need them in Darktable?
How do you see this and where do you see limitations in your daily work with Darktable? Are there things you would like to do with it that donāt work?
Thank you very much for your answer
Jo
