Having returned from a holiday in Asia, I showed my family the photo's taken while there and displayed them on my Macbook in Aperture full screen. Rather strangely the battery shut down after a couple of minutes viewing (from circa 66% charge), and when I plugged the power adapter in to charge the computer it had lost most of its application user settings - and Aperture had lost all of my image settings (it went about recovering the library photo's). Now I'm left with a few thousand RAW photo's which are uncropped, unrotated, ... etc. I've tried to recover all the meta data etc, but no luck, and so I'm currently faced with having to work on all those images - something I'm dreading to do! I was wondering if there is an Automator workflow to automatically carry out auto Exposure and Levels? Aperture gets it right 90% of the time anyway, and I'm figuring it could save a lot of time if I was able to do a batch process.
