I accidentally resetted my Nikon Z6iii before a shoot. Only afterwards I realized all the NEFs were in high efficiency format, which of course does not open in the latest Darktable nightly.
Fortunately, Adobe Digital Negative converter installs cleanly on Debian and the latest Wine. I tried before with version 14, with no luck, but the latest version 18 seems to convert the HE NEFs to DNGs that can be read by Darktable.
I shoot raw+jpeg always, so I still had the jpeg ooc which I think is too contrasty in color (camera set to standard picture control)
