I find that when I shoot, I generally want to delete about 75% of all the pictures I shoot. This not only helps keep my image repository clean and easy-to-browse-through, but it helps keeps down the size of my image files. (I've already amassed about 20 gigs of images!)
So far, I've been avoiding iPhoto because it doesn't seem to give you the power to delete images off your hard drive easily. For instance, when I go into my picture directories, I see folders labelled "Originals" -- does iPhoto store a second copy of all my images there?!?! That's going to be a lot of wasted storage for me!
Can anybody explain iPhoto's storage hierarchy to me? Do you have any suggestions for file management?
