for raw photo editing, embed sidecar files into images via a wrapper around exiftool
Problem: I want to backup my images and edits in amazon prime photos, but prime photos does not consider xmp(sidecar files) as image files and I dont want to pay any exta for non image storage.
Solution: Embed the xmp files into the image's exif metadata. Prime photos doesnt know the diffrence. Be able to extract and recreate the origional xmp files.
Applications sidecar's supported: Exposure x6
