This is a photograph that I took two weeks ago. While it’s not exactly a re-createable render I can provide the raw file and the darktable .xmp file!
Overall I like the lighting of this. It’s pretty modern and with simple gradients and it evokes feelings of Tron.
I down-scaled it to hit 5120x2880 but the original raw is 6048x4024. I’m happy to release it as CC-BY-SA-4.0 for KDE to use as a wallpaper.
