So after starting to use Maperture to geotag my photos, I’ve discovered that exported versions don’t include the GPS EXIF data (masters are ok). A few people have noticed this problem(1, 2), and there is a “fix.” This fix involves storing your piccies outside the Aperture library, which seems like a really sucky option to me.
I’ve found that exporting a project, and then reimporting it is an alternative solution. Evidently something doesn’t get updated when Maperture changes the original files (though the metadata turns up in Apertures info), but this gets re-done when the project is reimported.
Another thing I’ve noticed is that it doesn’t support DNG files. It will let you try and tag them, and adds the “Geotagged” keyword, but doesn’t edit or add the GPS exif data.
I just remembered my Aperture 2 install came with a bunch of example projects, nearly 3Gb of them in fact. Go delete them from /Macintosh HD/Library/Application Support/Aperture/ to get your quickly disappearing space back…
Always running out of space on your computer? Have iTunes and an iPod or two, and a lot of photos? I just cleared out 3Gb of thumbnails for my iPods that I never look at. Just remove the folder “iPod Photo Cache” from your iPhoto or Aperture library.
I recently realised (from the Aperture forums I think) that for the Aperture vault feature to work nicely one needs to have a Mac OS formatted drive to backup to. Previously my external drive was DOS formatted so I could read it from my PC, and the backup took forever. I also had this problem, which appears to have gone away, though I’m not sure if it was related. Now with my Mac OS Extended partition, the vault backup of my 25Gb library doesn’t even take a minute.
