My recent trip into posting old photos caused me to detour into organizing them as well. I thankfully found Darktable (https://darktable.org) and have since started the massive organization endeavor! Hopefully I’ll be able to get some nicer pictures up after the organization is done.
I also wanted to thank Darktable Landscapes (https://www.youtube.com/@DarktableLandscapes) for their very helpful organizational how to video. Answered all my questions and made my first ever experience with Darktable a breeze!
