I have been attempting to use the Photosmith app for keyword my photos. This of course means that I have to import the files into Lightroom and then share them with the Photosmith app. Since I happen to have a version of Lightroom that came with my Leica M when I received it I figured it would be worth a try.
Everything works fine on the lightroom side, however when I save the data to the files and the “sidecar” files is when I start having issues. When I import the files with the xmp files into Aperture I have some of the files that have the Keyword data and others that don't. It doesn't seem to have any rhyme or reason for when it works properly or when it doesn't.
