I am having a big issue lately where my free space is disappearing before my eyes. I free up 9 gb and within an hour or two its down to 2gb. I have been reading online and trying to free up space on my mac and have read that moving to Aperture is the best way to shrink my iPhoto library. I have copied iPhoto library to an external and deleted it from my mac, freeing up 45 gb of space. What is the best method to now get my photos from my external iPhoto backup into Aperture? I have been reading that different ways will either copy or not copy links between masters and previews and basically...1 way will make a large library, 1 way will make a smaller one. Any ideas?
