Why can iPhoto/Aperture see my EXIF tags?
Photo library applications cache metadata of managed photos. You need to trigger the reloading of metadata. In iPhoto, this feature is named “Rescan for Location”. In Aperture, you will use “Reload Metadata from EXIF”. Integration with Lightroom requires Lightroom to store metadata in XMP sidecar files. Once HoudahGeo has updated the sidecar, you will instruct Lightroom to “Reload Metadata from File”. HoudahGeo 2.3 can notify iPhoto’09 about changes to geotags. You may thus geotag photos already managed by iPhoto’09. HoudahGeo is able to detect photos managed by iPhoto’09 and offers to notify iPhoto of changes upon writing EXIF tags. For this feature to work, you must: • Use the latest version of iPhoto’09 • Have iPhoto library pre-loading enabled in HoudahGeo • Choose to tag masters/originals • Not have HoudahGeo create copies • Not have HoudahGeo create XMP sidecars Also, there should not be any existing XMP sidecars.
