Here's what I want to do... I want to import from iPhoto, with a view to ignoring its existence from here on. I've discovered that I can't do that directly, and besides, I also have bazillions of copies of all my photographs... all over my drives... so I am looking to consolidate. I want to be able to stop Lightroom from importing duplicates. I have several copies of many of the photographs and I really only need and want the originals/one copy in the app. Can do this? I've not yet noticed it as an option but have probably had my eyes closed. I think I probably want to store them on an ext drive, as well, so opinions about using a USB portable would be welcome. I'm running short of space on my internal drive and am not enamoured of the notion of having a honking great WD or Seagate... a USB portable is more convenient, but how is it working for others?
