Learning with darktable

Are you, by any chance, editing in a quite dark space and / or a bright screen?

The default pixls.us theme has a white background. That is a considerably different surround compared to darktable’s dark theme which is the surround you edit in.

Just try switching the pixls.us theme to dark (under Preferences → Interface). I think you’ll be surprised. One must not underestimate the perceptual effect caused by the change of the surround.

There may be something else in play too, but generally having the editing conditions in check is the first step and goes a long way (also for printing!). For one, I’ve fallen for this many times, editing in the dark late at night.

Maybe see if you can see the steps between black/white in this: Photo Friday: Monitor Calibration Tool

If not, then try using this to adjust

I thought this photo would be simpler to edit than it turned out to be, but it came out pretty good. But I make no claims to expertise.

I just opened your sidecar just to see how you developed the rock face… the sidecar was a bit off and then I noticed that you used a LUT… maybe share it if you can ie if its free :slight_smile: and so that we can see what it actually contributes …

Thanks for making me aware of this possibility to change the background here on pixls. (“Learning …” is the title of the thread, I think …). But from the philosophy of darktable, I would believe we ought rather to opt for Grey, than Dark (?).

Yes, that would give a better surround.

I like the first one better for the colors.
Here below my edit where I adjusted a few values in the quick access panel: I prefer it with a tad more contrast, saturation and warmth.

Sure, I used Landscape9.cube LUT from Landscapes LUT @ Free LUTs | Download Free LUTs for Lightroom, Photoshop, & More Online - ON1

See

and
darktable zoom artefacts in darkroom (and Preview window artefacts due to low quality resampling · Issue #10899 · darktable-org/darktable · GitHub)

The preview (in darkroom) is generated using the same code path as when export is scaled down, and high quality resampling is disabled. That is done for performance reasons. Sometimes, one has to zoom in to 100%.
It does not fix 10283, though.

And there are others, where the reason is not known (no dehaze, issue is visible without resizing / at 100% preview, some can reproduce, others cannot). An example is Darkroom view of processed raw image looks different from that of exported image · Issue #11741 · darktable-org/darktable · GitHub.

I usually have high quality resampling as without it some HDR photos get black spots in some photos especially in street lamps if I don’t use it. I think its when Haze Removal module was used. I might be able to still dig out an image that I can reproduct this issues everytime.

Thank you for these pointers, @g-man. I sorely need to recalibrate my monitor - or my eyes :wink:

Hi @Rykzon and welcome.

Both photos are very well captured, well done.

I have walked the countryside for many years and like to see pictures which reflect what I retrospectively imagine I have seen whilst out walking. This is what I see here.

If I have a preference, is it slightly in favour of the second option because you have managed to bring out the rock detail in the shadows without losing much of the depth of the shadows.

Still in the process of getting reacquainted with darktable. Edit no. 2:

Very dramatic edit on the rock face… nice…

Very nice image, @Rykzon! I think I prefer the tonality in your second image, but possibly the colouring in the first… both good IMO.
I seem to be feeling a little vivid :grinning: - possibly as a reaction to the cold, damp and grey weather here at the moment. Sorry - it could be called overcooked!
