In iPhoto I have 6,649 photos which take up 18.2GB in size (according to info), but in finder my iPhoto Library size is 35.2 GB... nearly double what it should be! Oh and I have about 8GB of videos. I'm not sure if "info" takes into account both pics and vids, but that would still leave a 10GB difference. What is the reason for the discrepancy? I'm trying to clean up unnecessary things on my Mac. I'd like to trim that 35GB down if I can.
