“One way to move iPhoto ratings into Adobe Bridge” by ben42 of Mac OS X Hints describes a process for moving your iPhoto ratings over to Adobe’s file organization & management software Bridge.
I wanted to move my (thousands of) images from iPhoto 6 albums into Adobe Bridge folders, but I didn’t want to lose my ratings. I never found a way to make the ratings readable in Bridge, but this method turns them into keywords that can be seen in Bridge.
This solution is a workaround for the lack of a direct way to transfer ratings from iPhoto to Adobe Bridge. The process is to create keywords for each iPhoto rating, convert them to IPTC keywords, and then export your images from iPhoto. A few different applications are required, but this definitely sounds better than doing the conversion manually.
