I want to stop using Lightroom and switch over to digiKam/darktable.
I have about 100,000 photos in one big Lightroom catalog. Most of these have never been processed.
However, I'd like to export all processed photos, so that I don't have to reprocess them in digiKam/darktable.
Is it possible to do this? Or am I going to have to go through my entire catalog and export them one at a time?
