It preserves EXIF, does not alter the RAW file, and you can add metadata to the JPEG/TIFF you create.
You *must* look at the videos in the Learning Centre before trying to use Bibble. It's a little unusual - not difficult once you are familiar, but you can get into a knot if you don't look at the instructions.
