As a new photographer (and Mac and ipad user), already at 90,000 images and have a mess! I use Lightroom to process and am thinking of emptying all photos out of iphoto, deleting it and starting over. I do use external drives as back up, but access the photos so often, prefer to keep as many as space will allow on MacBook Pro, with a selection synced to ipad. Am stuck! Is it a mistake to dump iphoto...it is only really used as a storage place to view as all my editing is in Lightroom. I can manage the photos in Pictures on my desktop, so why have iphoto. Do I need it to sync to my ipad (and hopefully soon an iphone)? I also have many duplicates and want an easy way to find them - which I thought would be easier once I chose where to manage the photos eg via Lightroom or iphoto. Any help really appreciated!
