I don't care about location data myself, but one of the key points
about KPA (to me, at any rate) is that it doesn't insist on modifying
files to store metadata. Every time you modify a file, something can
Another reason would be if you're using signed image files -- some
cameras can sign the files in-camera, which some people need for
evidentiary reasons. I would expect both the image data and metadata
to be covered by the signature; if you modify the EXIF header, you'd
break the signature.
