Darktable Episode 67: Advanced masking part 1: parametric masks

[@lordbasset2544]

I had no clue you could combine the mask inputs. That is some powerful stuff. Thank you!

[@edwardzhai6308]

Since following your videos, my photos have improved tremendously, thank you so much Boris

[@emrg777]

Great video Boris... the channel analysis will help a lot of people that I suspect are not aware of that feature of analysing the image to determing the best channels to target... I would be really interested to see how you might be able to edit that last image at some point by just playing with the internal masking tab of the color balance module compared to the approach you used... I tweak it a bit at times but I will usually fall back to using the standard module masking vs those controls... it might be a nice little add-on to your series to just illustrate how those controls fit in the overall scheme of masking when using that module...

I have been watching you for years and have learned a ton. Thank you so much!

[@bernym4047]

An excellent demonstration of dt masks. Thank you Boris.

[@filippetrovic8501]

Hvala, Borise, I veliki pozdrav iz Japana.

[@tomheller7405]

Thank you so much! Once again you showed me masking techniques that I wasn't quite sure about. I always learn so much from your videos.

[@nigearnold1308]

Superb - so many features I had no idea how to use properly and can now have a go at - thanks !

[@demarestk]

Another video by Boris, another lesson learned. Thank you so much for these videos. Edit: I didn't know you could push the c key to show the range of the parametric mask... That's really handy

[@arnaudm.7404]

Another very good lesson. I am very impatient to see the next video. Thank you so much Boris

[@vancouverbluesea]

Very good - thank you! I always learn something new from your videos.

[@cliffnieuwenhuis8638]

I am comfortable using the parametric masks and they have been very useful over the years but your video still managed to show me a thing or two I didn't know. Thank you! I look forward to watching part 2.

[@josefsmolik5991]

Again, I learned a lot of new. Great video. Thanks.

[@nir54321]

Great episode. Loved it. Learned lot of new things that were right there under my nose.

[@sanjeevvenkatesan3522]

Amazing tutorial. You have really made it so well to explain how to use. Thank you.

[@stephenward5133]

Thanks again. I have been using this software for nearly 2 years now and you still manage to tell me something really useful in every video. Clicking through the masks to see which one picks up the areas you need to address is really useful. Also using feather, blurring and opacity sliders together and showing what they achieve. I will have to watch this again though with DT open in front of me to make it sink in. Brilliant.

[@caigner]

Every time I watch one of your videos I learn something new. This time I discovered that when pressing 'c' you can display the channel data. Thanks!

[@FairMiles]

Me too! It's a great way to learn colour information (and someday, maybe, turn into that "intuition" Boris shows) Thanks!

[@huubdegroot]

Thank you soooo much!!! Love your video's and you always show things I didn't notice or use. Many thanks!!!! 🙂

[@ak4good]

Very useful examples, thank you!

[@sanjarnarzullaev]

Thank you

[@marciomendonca2423]

Great!!! Thank you so much!

[@enrikmonteiro]

Perfect explanation

[@xtra9996]

I guess that's the difference between commercial and paid software and open source / free software. Lightroom can do the same automatically in a fraction of a second. While this isn't always perfect in the end you save a lot of time. It's exactly those convenient functions that separates Lightroom / Photoshop from OSS solutions.

I hope this observation has convinced you enough now to buy Adobe subscription.

[@josspradel]

Hello Boris, Thanks you for all those great tips. Could you do a tutorial on how to create and use "styles" and presets to process large series of photos efficiently ? Thanks you very much

[@s7habo]

I don't use the styles because they only fit one limited number of images and in most cases still need to be corrected afterwards. I made an episode about creating the Kodakrome style (without comment). You can watch it here: kzbin.info/www/bejne/sJ3JqmuErcSCeas

[@hubertwermeester5550]

👍👍👍auch wenn das Video auf englisch ist habe ich viel verstanden ich bin begeistert👍👍👍

[@murlidhr]

if possible please do a video on highlight recovery

[@danport222]

At 21:30, you moved the modules around. My understanding was that modules in DT are processed in a consistent, fixed order. So if you were to go to the Active Modules tab, you would see that the order of those two modules can't be changed. Is that true in this case or did you have a different reason for moving the modules?

[@s7habo]

Please read this part of the documentation: darktable-org.github.io/dtdocs/en/darkroom/pixelpipe/the-pixelpipe-and-module-order/ With Contrast Equalizer I have reduced the rough part of the local contrast from the background. For this I created the parametric mask. After that I wanted to refine the same area even more and give it a slight foggy effect. But since the diffusion and sharpen module is hierarchically lower, I need to put it ABOVE the contrast equalizer, so that I could apply this effect AFTER I changed the texture with contrast equalizer. Also, I wanted to reuse the same mask from Contrast Equalizer, which is only possible if the diffusion and sharpen module is ABOVE Contrast Equalizer. The documentation says not to change the module order if you don't know what you are doing, because you risk getting artifacts. That doesn't mean you shouldn't change it if you know what you're doing. Active modules tab shows all active modules, if you changed the order, they will be shown there with changed order too.

[@danport222]

@@s7habo I see, thanks. I thought that what you did was only changing the presentation of the modules in the list. But, per your link, Ctrl+Shift to move modules around changes the order in the pipeline and regardless of which module section you're looking at.

[@Eigil_Skovgaard]

I welcome these tutorials where you reveal Darktable's darkest secrets ;O) One question to the last example. Would it be possible to subtract the foreground from a gradient mask, so the gradient only worked on the sky?

[@s7habo]

Yes, I plan to address that in the next episodes from this series with the masks. Darktable provides a lot more interesting options and combinations. With this episode I have just touched the subject :)

[@Eigil_Skovgaard]

@@s7habo Sounds promising, Boris. I am looking forward to the continuation.

[@GJRahul-rr3uk]

Is this by any chance photoshop?

[@s7habo]

No. This is Darktable. www.darktable.org/
