A brilliant side-by-side comparison of Filmic and Sigmoid. But above all, a clear explanation of the interactions between the remapping modules and the tone equalizer. I still haven't understood everything about the theory of stacking egif, then simple tone curve of the two instances of the equalizer, but it clearly works 🙂 . Also you have allowed me to understand the need to reduce the contrast slider in filmic. You've given me a key demonstration, after I'd been dancing around for a long time with the highlights. I admire the incredible clarity of your didactic methods and thank you very much for your fantastic work.
Very nice demonstration and explanation. Although I know what a tone mapper does the greyscale demonstration was a nice way to illustrate it and now I feel I understand it better. It certainly is a good tool to more clearly visualize what the modules are doing.
Wonderful video... your videos are always extremely informative and well narrated. I have personally been using Filmic for years... but always struggled with the color preservation... Sigmoid was easier for me out of the box great colors... I find myself not needing the super high dynamic range that often ... and when I do, then I can just switch back to Filmic. Thank you again.
I gave sigmoid a quick trial but then reverted to filmic as I found it too restrictive with its simpler interface. This is a very good demonstration of the two modules and where one scores over the other and vice versa. Than you.
Great examples and very interesting comparison. I find Sigmoid a lot faster to get a pleasing result and nice colors. With the Preserve Hue slider one has also more control about the treatment of blown out highlights. I managed to get really good results with images that just looked horrible in Filmic, no matter what I tried. And, again, the wish to use a bigger UI font for the videos so that they can easier be played in window mode instead of only fullscreen. It's so easy to do in darktable: just set the "GUI control and text DPI" in the general preferences to a higher value before filming.
Boris, have you ever shared your presets for tone equilizer? Would be very interesting to see what general settings fit for certain scenes to save some time here and there. Thanks
Filmic is great, but shifts colors. Very hard to correct whith color calibration. See the sky in your example. Before sigmoid, I spent tons of time to correct colors in filmic. Contrasts are better in filmic, nice look, more smooth, "analog", more details, e.g. in shadows. Great video, thanks.
Instead of the two instances of tone eq trick one can also use the local contrast module with parametric mask to increase the details in the highlights.
Very informative and well explained with examples. With 4.4.0, I get few modules in default when transferred to darkroom. These are White balance/Filmic and couple of others. I have to disable filmic and then work on Sigmoid. Why is it so and can I disable this default settings ? Thanks
Thank you for the demonstration. This Sigmoid result has more "summer" in it - imo. Did you say that Sigmoid responds better to later rgb-corrections? I think halos have been introduced in the sky around the flowers in the background - in both cases. Which module would be the sinner - the Diffuse or sharpen module or the Tone Equalizer - maybe both?
No, Sigmoid has a different algorithm for preservation of chroma than filmic, which works well in many cases but not always. This has little influence on the color corrections. I did not notice that with halo. Tone equalizer is to blame. If you increase the "edges refinement" in the masking tab, it disappears.
If you need some ideas for future videos; I would be very interested in seeing an edit of a concert photo (color balance when you have colored lights, highlight reconstruction of e.g. spotlights, denoising, ...) 😊

Boris strikes again! This is extremely useful. Thank you.
Wow, this is an awesome demonstration. Thank you!
Another great tutorial Boris, I've learnt a lot watching your videos 👏
Thank you for the nice comparison. I found the example at the beginning with the linear greyscale to be very instructive.
Thank you very much. Watching you for a couple of years, I have produced a success in editing my photos. Thanks again.
Great video; very educational part in the beginning. Great work👍

@@s7habo Very well, thank you.
Boris, wie hast Du das RAW File mit dem Graukeil erstellt?
Das ist keine Rohdatei. Das ist eine png Grafik, die ich in Inkscape kreiert habe.
If you need some ideas for future videos; I would be very interested in seeing an edit of a concert photo (color balance when you have colored lights, highlight reconstruction of e.g. spotlights, denoising, ...) 😊
For that I need a good example with appropriate usage rights. If you can provide that...
Is clarity a standard preset of defuse and sharpen?
No, this is my own.
@@s7habo can you cover how this works and what clarity is actually doing.
@@Photovintageguy Check Darktable Episode 61, there are also other Boris videos showing that module in more details
That's explained around minute 30 in the episode 61.
