  • An edited image of a bird, showing a more contrasty background than the original

    There’s a few artefacts and things in there because I was working with a pre edited webp file, but that’s what I’d do with it.

    This is my darktable module history.

    I used local contrast initially, but preferred how it looked without out, which is why it was turned off towards the end. The first color balance module was just using the “standard colorfulness” preset. The second color balance module boosted the luminance in the whole image, gave a bit more brightness to the shadows and mid tones, and increased the contrast. The final color balance module, I used a mask to isolate the background, and upped the contrast even more. This introduced artefacts in the background that wouldn’t be there if you did the same thing from a RAW file.

    And this is the mask I used in the final color balance module. I manually drew an area over the bird to exclude it, and then adjusted it slightly using the hue slider. I added a bit of feathering on the mask to get rid of harsh borders and to smooth out the impacts the artefacts had on the mask. Because I was only editing contrast, and not colour, the border didn’t need to be exact.


  • So if it were me, and assuming you’ve got an ORF (RAW) file for the photo, I’d use the color balance RGB module, and then play around with your shadows and power settings.

    If you’re really keen, you can use a parametric mask on the hz (luminance) and/or hue channels to select the background, and then boost the contrast of the background separately from the bird. Possibly give the background a little more saturation too.








  • Digikam is built from the ground up to be a photo cataloger. Hierarchical tags that you can click on to expand or contract, the ability to jump from a given photo to all photos taken on the same date, or all photos in the same folder, or all photos that share a particular tag. Collapsible folders and tag structures, the ability to toggle child tag/folder recursive view on or off, image grouping (automated by filename/timestamp/burst). They also share metadata perfectly well through EXIF data, so anything I do in one is visible in the other right away.

    This is digikam

    This is the same folder in darktable



  • I was one of the former. Photography isn’t my job, but it’s really important to me, and photo editing was a show stopper for me for a long time. Even after I moved to Linux full time, I was using remote desktops, VMs and whatever else I could manage to get Adobe stuff working, without having to switch back to Windows. I endured, because I’d finally hit a threshold where that pain was worth putting up with in preference to Windows and its built in ads and spyware.

    But when I finally gave up on getting Lightroom working on linux, I figured I had no choice but to learn a linux compatible workflow… It was either that, or go back to windows, and that wasn’t happening…
