Just wanted to give a big 'heads-up' to '
Darktable'
https://www.darktable.org/, probably my favourite photo-editor which is especially good for 'raw' file use. Unfortunately the version that is available through LL2.8 is rather out-dated (I had to add v2.0 from their PPA as my camera wasn't 'recognized' by v1.4)
Enjoy....
Tom
