Picked up Aperture 2 a few weeks ago to upgrade from iPhoto '08. Mainly since I found iPhoto a little limited with my new Canon XSi's raw photos. I like it a lot and really like the functionality. After installation, I imported my iPhoto library into Aperture without issue. I reorganized my photos, deleted duplicates, etc. I did run into one issue I'm not sure how to fix easily. When I imported my iPhoto '08 library, Aperture tagged all the shots with 'iPhoto Original' as a keyword. All that does is clutter up my metadata with useless info when I want to export it. I would like to delete this keyword from any photos that may have it(200-300 shots) but not sure if there is an easy way to do it. Since I reorganized them after import, they are mixed with photos added later directly to Aperture. I would think there would be an easy way to do this but haven't found an answer with my online searches. Any tips or tricks would be appreciated, thanks.
