Playing with masks after watching this, I noticed that right-clicking the input sliders highlighted them. The official manual gave no clue why but Stephan Hoek kindly explained that it enables you to move the sliders in single units using the keyboard arrows. Whilst trying this, I also found that holding down the shift key lets you move the sliders in 10 units. Todd Prior also pointed out that these values can be edited in preferences.
Thanks for the tutorial, very useful, as always. Just for the sake of sharing information, the slider struggle (at 10:48) can somewhat be reduced by clicking on the triangle you want to move, and using the mouse wheel or the arrow keys to nudge it in minimum increments left and right.
exactly what i am searching for. I am now at part two, but: thank you for clarifying it. I love your athmosphere, voice style. This is important for me, watching viedeos from a person. Thank you for it and greetings from germany
So glad I watched all this vid. I had missed the brilliant trick very near the end where you reversed the polarity to exclude the central section of the hue channel. That is just so cool. Thank you. I look forward to your next episode.
One little tip I find useful is the c key when hovering on a parametric channel. The maps the range of hues or Luma etc and helps you analyse and target the image....
@@audio2u I hadn't really either but I am starting to.. I have been using the tone eq and single channel blend modes to tweak highlights a bit as a sort of highlight recovery and so it's a quick way to see what hues are where...also maybe the best is for saturation ...helps to show you where that will help eliminate areas for masking
@@audio2u To me you can lose highlight detail with filmic..and filmic is global so the change impact other part of the image....but when you have some highlights at or near clipping you can tweak them nicely with the tone eq and say a red channel or other channel adjustment. Filmic preservation modes seem to really shift the color channels wet to one another...and in the highlight this behaviour can create nasty highlight that are hard to recover as one channel may be clipped or missing and one channel might be dramatically boosted by the color preservation modes. I saw Boris use this and I like the control and so I do this and often turn color preservation off in images with challenging highlights You can see the channel issues in the waveform but I find the waveform not bright enough for my eyes esp at the extreme edges
Very nice! Now I'm off to watch your video on scene vs display referred. :) I would be interested in a video covering the mask manager. There have been several times where I would like to use the intersection of two masks and sometimes I've succeeded and sometimes not, so a video on the manager would be nice. :) (But I guess that's already in the pipeline.)
I use color balance rgb with a hue channel parametric mask to target a color spectrum I want to enhance. 90% I just select the are with eyedropper+ tool and DT setup the slider automatically. I often use the 'c' key to visually check the selected channel in the picture.
Hi Bruce... thanks for this. I had worked out some amazing things in masking just using a rough drawn mask and tnen a combination of fethering radius, mask contrast (usualy in the upper 90's) blurring radius. to get semless blends for my masked areas. But this just adds anothe dimention... excellent. Btw masking was also one of the reasons I left Lightroom... Thanks...
Great refresher using parametric masks. Being colour blind I struggle with parametric and end up moving sliders and hoping the mask improves :) Thanks Bruce.
If this image was created at a different size and then resized, that could explain the slightly gradated / changed / uneven borders of flat color areas. If this is a JPG, that would be especially likely due to the typical patterns around flat color areas (and the limited color depth available in JPGs). Nice tutorial!
You probably said this in an earlier video that I had no time to watch yet, but: How do I 'apply' a change in settings to an image in a way that does not mess with the actual settings of the tool for the entire image, but only effects the masked area? Is that even possible? For example: Could you use the tool to change the hue on the entire image as well as on the mask?
@@audio2u I may said backwards what I meat. Trying to rephrase this: Can I use a tool more than once. So eg. increase the exposure of the entire image (without a mask) and then use a mask to lighten a specific part a bit more. So only apply a certain to the masked area even the tool is already in use for the entire image.
Once again outstanding work. I had no idea that I could mask based on luminosity. That's a great help! I have a devil of a time trying to mask a picture that I took of someone on a dark balcony with a sunny background. To give enough exposure to the subject, the background is overblown. Any suggestions about which combination of masks to use here?
For that, I would suggest you wait until you get tot he end of the series on Masks (of which, this was pt 2). I think you'll find that the episode relating to intersection of masks will probably answer your question!
@@audio2u That is fine. Thank you again for the prompt answer. One of my problem with the masking in Darktable is the lack of a layer concept that means to collect a set of related processing steps under one directly adressable entity with a meaningful name e g. "sky". By the way how can a duplicated module get a meaningful extension name?
Is it possible to zoom in to 100 percent, i.e. 1:1, in order to pixel peep? It's possible in RawTherapee, but I haven't found the way in Darktable's Darkroom during my initial attempt.
HI Bruce. I've not touched Darktable or my camera for some time. I noticed that my Darktable has updated to 3.8 and I have hit a snag. I wanted to convert a pic to B&W using Colour Zones but I can't see how this now works. Can you please do a quick video or reply to this telling me where to get the same effects as I did in Darktable 3.6. Thanks in advance.
Ideally, you would skip the CZ module and use the colour balance RGB module instead (due to CZ using a display-referred algorithm, while cbrgb uses scene-referred code). But functionally, nothing in the colour zones module has changed, that I'm aware of. If you've used it in the past, it should still be the same.
I have another question in the category - must haves. I see there's a limited number of algorithms for demosaicing, but can I select ProPhoto RGB as my color space? - like in RawTherapee and ACR? Here follows a political statement: I dream of the best from RawTherapee and Darktable combined in one single software. Existing as two separate apps they both exclude vital features. Surprisingly, when I aired such coordinated development to the responsible creators, it brought me in trouble. Actually I was only suggesting a real brush in RawTherapee - but that immediately led to chaos in the forum and I was kicked out! An eternal loss. That's another side of free software. You are free to be thankful with what you get and avoid to "demand" improvements. In other words - there's no marketing with a business minded portal anywhere - take it and use as is, or leave it. This attitude finally made me kiss RawTherapee 5.8 goodbye, and that's why 12 usd per month to Adobe for the development suite still feels fair. So, looking into Darktable is somewhat colored by earlier experiences with free software and its support.
Interesting thoughts on free and open source software! As for using the pro photo colour space, I'm fairly sure that IS an option in the input colour profile module. You could even create a rule that all imported images are switched to that colour space if that's what you really wanted.
In general it's a very interesting and helpfull video. However: Why did you complain about net-man's image? If you want something better why didn't you create it yourself or payed for a professional slide? Also the image looks like some compressed JPG file from the web. So I could imagine that the observed colour inbalances are caused by the lossy JPG compression. I don't mean to be rude here, but the two times you complained about the image left a _stain_ on that video for me and in my opinion these few seconds reduced the quality of the entire video. I am also not a fan of sound effects that serve no direct purpose (eg 2:31). For me they also make the video look less 'professional' but rather more childish. I hope you don't see my words as attacking or unfriendly. They are meant as constructive criticism. If you want to keep your style it's fine too.
You are the Boss. No one has dived so deep to understand and explain darktable. Thank you Bruce.
Thanks for the kind words! 😊

Yeah, great find!
And if you hold Ctrl, you move 0.1 units.
That is great, now you have total control.
I always come back to revisit your videos of the parametric masks. Great explanation.
Thanks!

Good to know!
Great, now you can choose an exact value. But you don't need to click on it, you can just hover over it.
Additionally, you can, at the same time, holding Shift to increase 10 times the amount of change, or Ctrl to decrease 10 times the amount of change.
That was a cracking tutorial, I now understand a heck of a lot more about parametric masks. Thanks Bruce.
Good to hear!

Whenever I see "reverse the polarity", I think of Dr Who "reverse the polarity of the Neutron flow".

For that, you use whatever module you want but without any mask.

No. But you can use two instances of the module to achieve the same end.

Luminosity, targeting the shadows, clearly! 😃
How to directly delete not wanted parts e.g. in the last example with the car?

@@audio2u Thank you for the promptly answer, I will wait, but I referred to the eraser brushes in Capture 1 and Lightroom....
Sadly, darktable does not use pixel-based masking, which is a real pity. Because of that, there's no such thing as an eraser brush.
I'm actually considering a video on this exact topic.
@@audio2u That is fine. Thank you again for the prompt answer.
