I've been using Rawtherapee for post processing for a short while, and, even though I've been able to adapt well my workflow to it, I've found that having to look through most of the photos I took just to rate them (So I can later filter them) is a quite cumbersome process.
I've been looking to include Digikam in my workflow mostly for organizational purposes, and I've found that opening and rating the shots is an easier and quick task with this tool than with Rawtherapee.
So, right now, my idea of workflow should be:
1) Download images from camera (d'uh)
2) Open them on Digikam. Delete bad shots, rate the rest of the shots.
3) Open the folder on Rawtherappe, make the program read the Digikam ratings and filter photos.
I've been doing a bit of research and found that this is handled through "sidecar" files, but it looks like Digicam creates XMP files (If asked to create a separate sidecar file, of course) and Rawtherapee goes for the pp3 extension.
And now I'm stuck. There's any easy way to convert from one to the other, maybe I can configure either rawtherapee or digikam to read/write the other program sidecar files? Should I take a different approach (Namely, just moving the discarded photos to a /EventFolder/Discards manually or through a script)?
