Hi, I just bought the Canon Rebel T1i last month and I'm loving it so far. I have been using iPhoto, and I really like how you can manage all of your photos in one place and all the other extras (e.g. faces, places, facebook, etc). Since I'll be shooting in RAW with the new camera, I'm planning to move over to either Aperture or Lightroom. I'm using the trial version of Aperture and Lightroom 3 Beta now. Do you know what's the best way to manage my photo library? Is there a way to manage all of my photos in one place, and be able to easily upload my pictures to Facebook or face detection? I know in Aperture I can import photos from my iPhoto library, and either copy over the the Aperture library or leave it in its current location without re-importing again. If I leave it in its current location, where are the modified files stored? Do most of you maintain more than just one library (eg 1 for iphoto, one for Aperture)? Any suggestion would be greatly appreciated. Thank you.
