I used LR for several years, now I want to switch to Darktable. I read the blog post about the LR sidecar files that are read by Darktable. However, LR only creates the sidecar files for RAW files of camera manufactures. JPG files and also DNG files have no sidecar files, because all development data is written into the file. I have converted all my RAW files to DNGs, to save space and to benefit of the speed increase. I have only JPGs and DNGs. So my whole LR catalog has no sidecar files, as you can also see in the screenshot.
I imported all my files with Darktable. The development data has been saved into my DNG and JPG files. But Darktable does not recognize any development settings.
Are DNG and JPG files not supported for importing development settings? What can I do to import my LR development data into Darktable?
