  • 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.











  • I’ve been using my real name on the internet for 30 years or so now. I’ve hosted public radio shows, I run/admin several online LGBTQ communities and I’ve had newspapers articles done about my transition and activism.

    It’s absolutely possible that someone with the desire could utilise that against me. But it’s unlikely and it hasn’t happened yet. And in the mean time, having to hold myself back and be constantly on edge about what I say and where I say it would impact my use of the internet in a way I don’t like, every single time I use it.

    So for me, it’s worth the risk.



  • I like themed instances and would enjoy them more if the All feed were personalized instead of the same for everyone.

    That’s what your subscribed feed is for…

    But choosing an instance that fits you best isn’t possible

    It doesn’t need to be the best fitting instance possible. It just needs to be an instance that lets you use and interact with the fediverse in a way that works with you. That’s why a lot of people use generalist instances. They’re no ones “best fit”, but they are also less likely to be bad fits for folk…
