iPhoto is great for organizing and managing jpgs, but sucks for RAW files. It creates a jpg file for every RAW upon import, and that eats up space very quickly. I've been looking for an easier way to manage my RAW workflow, and fiddling a bit with Lightroom, it appears to be what I want. Has any of you ever transferred all your RAW files from iPhoto to Lightroom? If so, how have you done it? What problems have you encountered?
