I currently use LR2 and use the export feature to keep a separate copy of some of my albums available at lower resolution for use in iPhoto so that I can use them for desktop wallpapers, use with my iPhones, iPads, etc. I'm considering upgrading to LR3 and at the same time want to do some housekeeping to make this work better. I'm looking for a way of automating keeping my LR3 albums synchronized in iPhoto, if such a thing is possible. The export method is fine, but it's manual and a bit tedious. I've also occasionally gotten duplicates of certain photos when I export the same album after making changes (or the duplicate with changes doesn't show up unless I explicitly delete the old version 1st which is very difficult). I know some of you will probably say I should just use Aperture 3 if I want to use iPhoto but I really like the work flow and features in LR and it would be extremely painstaking to edit my thousands of photos in a new management platform. Does anyone have any advice?
