after editing some RAW files I exported them to JPEG (via File-Export and export persona). Unfortunately the EXIF data is partly wiped. You can also see it in the screenshots attached.
One side effect of this:
I mostly collect my photos (RAW and JPEG) in the Photos.app on the Mac and my iDevices. If I import the RAWs and JPEGs directly from my cam, Photos.app recognizes that they belong together. This seems to be made by comparing the EXIF information of the pictures (maybe date of shot?). But if I edit a RAW in AP and export it as JPEG (same filename), the Photos.app don't longer recognizes, that both pictures belong together. Because of that all edited photos are twice in my photo library. I really liked the fact, that Photos.app combined the RAW with the edited JPEG and only showed the edited one, but you could also export the original RAW.
Hopefully my text is mostly understandable as I'm not a native English speaker ;)
