that is editing on a whole new level. just amazing. And I have to admit, once one knows how to deal with Darktable, there is nothing better out there. thanks for showing
Just amazing, that last image has really shown the power of understanding how to manage colours. I've always struggled with understanding how to remove some of the tint I get in my images. I really need to practice this. Thank you so much for taking the time to explain this Boris.
I think you’ve surpassed yourself with this video and that’s coming from an already high bar. I can’t recall anticipating part 2 of anything so much as this set.
This is why I love your videos, I was expecting it all to be color balance rgb and instead you used color calibration differently than I had ever considered to get beautiful results.
Thank you Boris - absolutely brilliant tutorial. I've always stayed away from the colour calibration RGB input channel sliders because I've always made a mess of things. I can see now that using the colour harmony tools within the vector scope is what would have helped to use these sliders correctly. Can't wait to watch parts 2-4 of the series.
I love watching your videos. I am taking photographs as a hobby and I often use your videos as reference when developing some raw images. Thanks for putting in the effort. I am excited for more.
Really helpful as ever. I jumped straight in and edited a couple of images yesterday and did get some excellent results. Still struggling a bit with the channel mixer but getting there... Thanks again.
Anther wonderful and informative episode Boris!!! Thank you for your time and effort to share your knowledge and skills with us. Already anticipating the next part!!!😊
Amazing editing as usual! Would love to see the last image with the blue pushed a bit towards purple to make it symmetrically opposite against the yellows.
Hi Boris, once again you delivered a brilliant piece of work! While experimenting with the color picker it struck me that the color picker points I've selected disappeared when I switched from the darkroom to the lighttable and back again. Did you experience this behaviour also?
Hi Boris, thanks for your constant efforts sharing your deep knowledge and practice. Thanks also to advise watching Joanna Kustras video which was eye opening to which level you can bring color as an art form. However, I wonder if one can achieve the same astonishing results (done in PS) with the tools of DT. What do you think?
Yes, it is possible. However, she stages her photos. She thinks a lot about color composition already during the photo shoot. Even in non-staged photos, she takes into account the given light and color conditions and thinks carefully about where to place her model. This facilitates later decisions about the color composition of the photo during processing. And I must say, she has a very good eye for color composition. And that is much more important than the tools she uses. You really need time to learn something like that and gain a lot of experience.
Fantastic tutorial as usual. Thank you! I also noticed that in your videos, you never use the "auto picker" buttons in the filmic's white and black relative exposure sliders. Why is that? In other tutorials by other people they often say that that kind of tuning is important at the beginning of an editing as to set the "boundaries" of the dynamic range of an image. I'm a bit confused about those sliders.
Please read the documentation here: darktable-org.github.io/dtdocs/en/module-reference/processing-modules/filmic-rgb/ Your question is answered under "dynamic range scaling and auto-tune" subheading.
Around 29 mins there’s a use of color calibration input RGB to adjust colors, I’ve watched other videos about color changes and it’s primarily done with Color balance RGB module. Why can’t that be the case here? I’m a bit confused on which modules are for more “creative” use and which are meant to set up the backend of color calculations
Color calibration module is a powerful module that contains various functions, including channel mixer, a tool with which you can make both corrective and creative color changes. The boundaries between these two forms of use are fluid. Channel mixer is also often used for color grading in a similar way to the color balance module. In contrast to color balance, however, which can be used to change the color of different brightness ranges, channel mixer influences the ratios between three primary colors. That is why it is placed on the level of color calibration, because in a similar way, for example, the white balance is made. To separate corrective from creative application, in that part of the video you mentioned, I used channel mixer functionality in a new instance of color calibration module. One reason why many don't use channel mixer is because it's not very intuitive and requires a knowledge of how the three primary colors (channels) are combined together. I have made several episodes about this and I recommend you to watch them.
@@s7habo Thank you for elaborating and specifying when the use case is for a creative application! The when/where/how of applying creative decisions without impacting the backend math is where I struggle. Haha I would like to avoid turning/moving nobs/sliders without much thought
I don't use Lightroom and so unfortunately I can't say anything about it. Darktable also has color zones module, which allows you to change different colors at the same time. I don't like to use it because it's not part of the scene-reffered workflow. Besides, it's not only about global color changes but subject oriented, which requires a lot of masking. I can't imagine that you could do that with just one instance.
@@s7habo I see. Thanks for the explanation. I will look into the color zones module. It seems to me that if I only mask based on colors, then color zones is easier.
Impressive demonstration, Boris - But the mixer rules are hurting me ;O/ E.g. How do I remove yellow? Is it by reducing green and red - or by adding blue? I usually find out through t & e (the painful part). I would love to be able to do it right the first time.
Yellow is the same proportion of red and green in the ABSENCE of blue. So, you have to add blue. This simple color scheme about composition of three color channels can help here: en.wiktionary.org/wiki/RGB#/media/File:The_three_primary_colors_of_RGB_Color_Model_(Red,_Green,_Blue).png
The special case of the channel mixer is that you can use ratios of all color channels to influence all color channels. This confuses people. For example, you want to remove the yellow from the flower. You activate "B" channel because you want to add blue. Now you don't use "input blue" to add blue because the flower doesn't contain any blue. So, by doing this, you are adding blue everywhere and LEAST OF ALL to the flower. So you use another input, preferably "input red" to increase blue, because the red channel is much more "represented" in the flower than the blue channel. So, if you use its "ratio", blue will be increased there much more than in the environment, where there is little amount of red. You could also use input green, but if the environment of the flower has a lot of green stuff (leaves of the plant), you will increase the blue there the most, because the green channel is represented there the most.
Yep, thank you for the explanation. I already have the RGB model in front of me as a constant reminder. I also understand the theory (I think), but so far the training has not been sufficient. There are pretty many combinations, and it's important to decide correctly, which color has to be removed/absorbed.
@@Eigil_Skovgaard Yes, this is the hardest part. I have found it very useful to use the vectorscope in combination with the color picker like in this video to better observe how the colors shift when using the channel mixer.
I use waveform and the dynamic range is, unlike the histogram, displayed vertically. The boundary is indicated by upper dotted line: darktable-org.github.io/dtdocs/en/module-reference/utility-modules/shared/scopes/

Thank you so much for taking the time to explain this Boris.
Wow, thanks so much. Joanna's was a great introduction, followed by your demo which revealed a whole new world in darktable. Fantastic!
Please make more examples of colour harmonies. Your videos are so instructive. I can not find one other that can compete with you on TH-cam.
l hope you will make more videos on colour handling. Never mind if you repeat your actions. You are so good at explaining how to do it.
I had a big smile on my face when you finished, Boris.
It was like magic.
Thanks

As you said, subtle changes but interesting to see the overall impact.
Appreciate your lessons, and look forward to the next!
everytime i watch one of your videos I seem to understand color and contrast much better then i knew before.
I love watching your videos. I am taking photographs as a hobby and I often use your videos as reference when developing some raw images.
Thanks for putting in the effort. I am excited for more.
Thanks Boris, it is great learning from you
A master class in the use of color calibration. Great work, thanks!

Thank you so much for your knowledge and pedagogy. I am taking notes along and I already made huge progress thanks to you !
Cheers !
Boris, your tutorials are A-MA-ZING!!!! Thank you very much!!!!!
Thank you again DarkMaster. Joanna's film about color theory is absolute fantastic, she is such a great photographer.
Once again such an excellent tutorial especially I got more clarity on color mixer in this video. Amazing video!
It's always fun to watch the master at work. 😀
Awesome video. Channel mixer still one of the most difficult tools to actually use (understanding it is not the same as using it the right way 😊)
Great job Boris, always enjoy your video!
Sir, You are amazing. I learn so much from your videos. Thank you.
thanks Boris i always enjoy watching your videos
Amazing video again. You are a true darktable magician. Thanks very much.
Thank you soo much Boris!!! Learning a lot from your videos. Love it!!!
Amazing editing as usual!
Would love to see the last image with the blue pushed a bit towards purple to make it symmetrically opposite against the yellows.
Hello!. I learned a lot and enjoy with yours videos. Thank you!!
Absolument génial, un grand merci
Thank you very much for this extremely helpful explanation 😊
excellent as always.

Thank you for sharing your work with us. I’m switch to dark room from Lightroom. Can this software create panorama with multiple images ?

Instead of using multiple instances of color mixers, would a lightroom HSL function be better and much easier?

Either you don't have the latest darktable version (4.4) or you haven't switched the color space in the upper right corner of vectrosocpe yet.

Hi, Since you don't use a typical histogram, how do you know what the correct exposure is?
I use waveform and the dynamic range is, unlike the histogram, displayed vertically. The boundary is indicated by upper dotted line:
darktable-org.github.io/dtdocs/en/module-reference/utility-modules/shared/scopes/
@@s7habothose dotted lines would be much more helpful if they were visible. I struggle to recognize them.
