Struggle to deal with high dynamic images

Thanks all, so I had a bit more time to try to study your art, thanks again everyone I learn a lot in this process! I’m not completely done, but for reference here is a comparison of the different methods with the advantage/drawbacks I can see:

As usual, an incredible edit… also in the number of used module, I’ll still need to spend a few hours to study it!! The contrast is maybe pushed a tiny bit too much, but this gives a really “pro” look, I love it. So to expend on the above analysis, I also see that with the exposure module, you have neither exposed the background, nor the faces, but you expose in between, so the faces are still a bit dark after the exposure,

So here you exposed also in between, and just used two decreasing tone equalizers like this:

so we do see both background and faces, but you have similar issues to the one I experienced with faces with fairly low contrast like:

compared to the original

It may be possible to play with contrast equalizers/… to make this look good as well, I need to learn how to manage contrast!

I tried your edit, but I’m wondering if it loaded fine: I can see:

but it seems that faces are very dark (eg compared to your second edit where faces look much better) and in the list of applied module I just see one instance of color balance rgb (what is TE?). Am I missing something or was it the intended look? (darktable 5.4.1)

I really liked here the fact that the background is really visible and not too bright, but sadly when I apply this style on my actual image the contrast of the faces of my friend is really low which gives a really weird look (on my face that was not hidden it’s not very visible, so it’s not your fault here ^^ Funnily enough in yours you have no AgX/sigmoid/filmic… interesting! So here you exposed for the background, used two instances of tone equalizer to expose the faces, and local contrast/contrast equalizer to deal with the contrast + color balance rgb to push saturation a bit.

That’s a cool one, simpler than popanz’s in number of modules, and with a more “natural” style, but contrast is still decent, and both faces and the background appear clearly. Faces are maybe a bit underexposed and contrast could be pushed a bit more, but I like it a lot as well given the number of used modules! And I learned one thing: if you expose for the background and use contrast: -50% in color balance rgb, you can bring back light in the dark areas (here the faces ^^) and still get something decent! (well as you mention contrast is added back via AgX, so you need both modules to work together)

Anyway, I’ll continue to play and learn from your edits, thanks all again!

Funny, I also though that doing WB in WB was kind of deprecated/not recommended ^^ Seems like there is theory and practice! Out of curiosity, why do you do it that way? Just because yoa are used to this method or is there a more fundamental reason?

Btw if you have some good resources for how to deal with contrast please let me know!

Edit: I need to see https://youtu.be/VQGoCyns7_g?si=TDLQbv6JBoxKgLgU

Colour calibration was published with the “promise” of being more accurate. So I switched to it and all in all it worked fine.

But from time to time I had pictures, where I found some colours strange (mostly violet and purple tones) which looked differently to what I expected them to look. So on these pictures I started to compare with the good old WB module and they gave me a more pleasant look. That was the time when I switched back. Not because colour calibration gave me a worse output. That is in general not true. On some cases it works better than the old module on some worse and most of the time there is no relevant difference.

But as it gave me not in general a better result I decided to switch back. I often alter the white balance manually and for doing this quickly and intuitive, the old module offers me a MUCH more pleasant and understandable interface.

There is a somewhat strange guy here on that forum. He loves to participate in Play RAW. He has a weakness for contrasts. Look at his XMPs. :rofl:

Boris Hajducovic has a good youtube video on tone equalizer…

Another video I must rewatch to try to understand. I don’t even know how he manages to get a straight-line “curve” in his remove-contrast TE instance.

Magic touch perhaps!

@s7habo … Missing your videos: I hope all is well.

Use the simple tab where you can right-click and enter the exact value. The only good use I have found for that tab :rofl:

I’ve had issues where Color Calibration is unable to home in on illuminant and I wind up with a color cast that’s difficult to recover from. Usually this is a green or magenta tint that requires tweaking either in the custom option or within the green channel mixer tab. It can take an inordinate amount of time to fix, and sometimes I still discover residual casts after walking away for a while.

The White Balance module may not be as sophisticated but having to direct temperature and tint controls working is straightforward and easier.

Nice idea!

There are presets floating around with the straight curves going through the middle and starting from 0 up and down… I will see if I can find them…they are by default named in French IIRC

Considering how often these come up here they might be worth a PR to include with dt by default?

I wish I had known that before. When I’m experimenting with the straight line method, it is a constant readjustment of each node, as sliding one node changes the nearby nodes’ settings. I’m going off to experiment with this. Thanks.

PS - Works like a charm. Thanks again.

@Tim Here you go these have been shared at one time or another…

toneequal_Basses Lumières_ – _ 1.0 IL.zip (24.3 KB)

These are graded versions of relight…


so shadows up or down



When using these I tweak the mask exp comp to slide it back and forth to a good spot and then sometimes I will go to the line and introduce a small curve or adjustment…

Sure, but it’s hard to read everything that’s posted here, and it’s hard to remember everything that you have read.

Thank you!

I do use the simple tab, although I haven’t tried right-clicking.

Most common use for me: I want to steeply reduce the highest highlights.

Next most common use for me: I want to make subtle changes to adjacent nodes.

I am not sure if people use TE for subtle contrast control, eg the shadow gradient on the side of a face. Can be done (without the curve-math snake throwing a hissy fit).

Apart from highlight drop, if it isn’t a subtle thing, I’d rather be using CB-RGB anyway.

Thank you :slight_smile:
Will take a look at that.

Now giving notice to my brain that I will need to recall how to import presets. It does have that memory somewhere.

(I think its in the settings window)

Thanks for the feedback. I’m still here, but I’m currently in “low-key mode” due to poor health.

I hope to continue making videos soon anyway. That’s definitely my plan. I can’t say exactly when yet.
