Just a hello all Linux fans.
The more I use Darktable, the more I love it.
I previous would use take a DNG, into Ufraw, then into Gimp. Darktable really takes a lot of time out of this. When happy with a Jpeg, I would resize it to various resolutions, darktable saves a great deal of time :P
I confess I strongly disliked the interface, but it's manageable. Oh to save your hair... set all the tools you regularly use into the favs menu, then you will not be digging through those menus every again
Sorry long story short, if you haven't used darktable. give it a go.
