I've recently done a small test of Picasa, and was very impressed by its geographic presentation (the Google maps integration is way nicer than what I previously used - Microsoft Expression Media). So, as a follow-up, I tried to geo-tag a photo in Picasa, and was disapointed to see that the file was not updated in OS. So.
Does Picasa really store geotagging in photo files ?
Or does it save this information in its non-standard, vendor-lockin DB ? And if so, is there a way to transfer this locked information into IPTC tags ?
