What's still *not* working perfectly is multimonitor handling (with a different ICC profile for each monitor). #Rawtherapee kind of handles that by offering an always-visible ICC profile select field. Other applications, like #digiKam, #nomacs and #Gwenview, are color managed but (at least on Ubuntu 24 with X11) either (1) always use the primary display's ICC profile or (2) require diving in the menus to set it.
Next to robotics, I enjoy photography and that includes developing pictures. A few weekends back got #digiKam and #Rawtherapee color managed using #DisplayCAL I thought some of you would be interested, so wrote down the steps at https://arnebaeyens.com/blog/2026/linux-display-calibration/

Black Sheep

A starling with leucism in the midst of its flock.
Unfortunately, I could not get closer or find a better angle, so you'll have to live with this more artsy processing.

Wings of a Chaffinch

This chaffinch found something interesting on a branch where it could not perch. It repeatedly hovered for a few seconds above the branch, pecking at whatever was on it. This gave me plenty of opportunities to catch its wings backlit by the sun.

Remember the other day when I couldn't find my pics of the tarantula hawk wasp because I moved to Linux and hadn't settled on an image manager?

digiKam for the win. It'll take another half day at least to finish cataloguing, but it found my image almost instantly. Automatically cataloguing EXIF, IPTC, XMP and MakerNote data too.

Oh, here's the photo...50mm lens, hence being so frightened when I shot the photo πŸ˜‚

I noticed that @digikam is lacking functionality for only exporting face thumbnails for a certain person. Here you go --> https://github.com/superFelix5000/digikam-face-thumbnails-export
- using either Docker so no local dependency installs necessary or you can pick and choose the tools from the repo yourself. Also including functionaliy deduping the images. Yes it is vibecoded mostly *raising hands in the air* - though I read through the code ☝️ and corrected parts of it myself. Tested it somewhat on linux. #digikam #facerecognition
