- In this episode, we take a look at the equalizer module, which along with being able to be used to alter contrast in a variety of interesting ways, can also be used for noise reduction purposes.
Really impressed with that equalizer. Good tip about bumping the central sliders. I always appreciate tools that make a significant impact but do so in a subtle way.
Absolutely!
This has become a "go to" tool in my DT toolbox. Even the presets are marvelous and quick to use!
Cool. I don't think I've used it since I did this episode! :) Each to their own!
Another great video on Darktable...thank you for all your insight with this application and its module. Have a pleasant and safe cruise with the family.
Thanks Denis! Will do! 😀
I hope there's someone watching your home. In these days, I don't think that safe say to the world all that information about your vacations. I hope all go great with your holidays anyway.
Thank you so much for sharing! For so long, I had just been using the "sharpen" module which always brought up the noise levels. This is incredible thank you again for such a detailed video!
Glad it helped!
You have got amazing content on darktable and I look forward to every video you have on explaining the modules.
Thanks zephyr!
6:08 Changes are not noticeable as you say. What you miss is the black bars in the background of the diagram. They show you which part of the changes are visible in the image at the current zoom level. So, on the right side where there are no black bars, you cannot see changes in this zoom level. You need to zoom in to see.
Regarding the problem in applying two styles, there is a couple of options in "history stack" module of lighttable view that might help:
1. You can reset history stacks (discard previous edits) on selected images by clicking "discard" button
2. Selecting "overwrite" for "mode" will reset history stack before applying the new style
Thanks Masoud. I think the issue he had, and it was the same for me, was that lets say I had 4-5 steps in the history stack which we'll call the "basic set up and correction" steps (orientation, sharpen, white balance, exposure, etc), followed by some other steps which we'll call the "creative" ones. Things like CBS, tone curve, color zone, tone mapping, etc. And I generally create styles which only feature those creative steps. That's where it gets a bit messy.
I think you can do the opposite. Fist applying the "creative" steps using a style, and then applying the basic ones. Is really counter-intuitive, I know, it's just me thinking about this potentially serious fault of darktable.
I see. There is no "undo" functionality for applying styles at the moment but I think you can do it this way:
1. Open one of the images you have already applied the style
2. Instead of reverting back in history stack, turn off all those iops enabled by the style
3. Go back to lighttable view and copy history stack of that image
4. Select all images you want the "undo" the style on them
5. Press Ctrl-Shift-V (or "paste" button from "history stack" module). This will open a new window that shows the copied history stack. Select only the disabled iops in step 2 and press Ok button
This way is not so user-friendly but I think it is worth if you want to undo a style on a lot of photos. Instead of step 5, you can also create a "secondary" style including those disabled iops if you want to undo a specific style frequently.
Hope this helps.
Thank you for this video.
I thought, I was stupid, because I never saw a difference with that tool at the edges as well. Zooming in or out doesn't change that. The Equalizer is turned of in my Darktable. I think, I prefer the Local Contrast tool, which will be episode 29. Can't wait to see that ;-)
ACDSee Pro has an Equalizer tool as well by the way. But it works different. Wished, Darktable had that too, but I guess, ACDSee would sue the Darktable team for anything they have.
Glad you found the video useful!
There is a module that I don't understand very well its functioning and I think it would give a great video. It is zone system!
Just a thought ee the style issue, what about creating copies of the original image. Copy the history stack from the copy you first edited up to the point before you apply a style. Apply that to each of your copies and then try out your different styles on the different copies to see which one you like.
I think this module is renamed to "Contrast Equalizer" in darktable release 3.0.
there is enough in 2.4 to turn it into a university course
Another module that deserves a video for itself is color zones. Could you make such a video? It would be awesome.
I'll get there eventually! :)
That would be good.
When you want to apply Style 2 after applying Style 1, can you not create Style 2 so that it uses (and resets) the Style 1 modules first?
Oh, and bit late but Merry Christmas and hope you are enjoying your cruise!
I guess that would be one way around it, but it is rather a lot of "double-handling".
The cruise was great, thanks! Got back to Sydney this morning. Had a nice Christmas Day at sea! Cheers.
Hi I'm somebody :) I have changed my name Thank you for atention and your job! Have a nice holydays/
Haha! Thanks Alex! I shall, and I wish you a merry Christmas and a happy New year also.
I think he's Russian, not Greek.
I was thinking that after I'd recorded! I suspect you are correct. Apologies to Alex!
That's the Cyrillic alphabet (may be Ukranian or so).
@@audio2u Google translate to the rescue, let it detect the language and translate it to English. You can try it with Алекс Николаев :)
Uuuuh what a fart that was. It did do me so well...
