I was looking at my iPhoto library file and it is 27gb. I know iPhoto stores originals and modified versions of the same image so you can revert if you want. I don't do editing in iPhoto and noticed my modified folder was just over 2gb. I went into the library file structure and looked at the modified file it had in there. It was a picture I imported two days ago. Never did any touchups or any editing to it yet it is in the modified folder. Went looking through the modified folder more and all the images are ones I have never touched. If I go to the picture in iPhoto I can't revert to original on them either so why are they in the modified folder? Any ideas? I want to try to trim the library size down if I can.
