I start with a pair of RAW+JPG files, open them from Photo Mechanic Version 6.0, build 4538 (51e5663) to Luminar 4.1 with the Edit Photo in Luminar 4 command. I edit and export the file back to the same folder. Luminar 4 uses *.jpeg, not *.jpg file extension.
Then PM6 sometimes pairs the RAW+JPEG files, and sometimes the RAW+JPG. After a restart of PM6 the files are back to the normal RAW+JPG pair.
The RAW files I was working with today was from Olympus OM-D E-M5iii (ORF) and Panasonic G9 (RW2) cameras.
Hope you can look into that.
Thanks for a great program!
