iPhoto shows right date - wrong date in Finder
I am experiencing a problem and I'm not sure if it really is some kind of bug or maybe I'm just not getting it.
When I open a photo in iPhoto I can see the date the pic was taken (April 11). When I copy the picture out of iPhoto and open the information window by right clicking the photo on my desktop it tells me the pic was taken on May 5 (which was the date I edited the photo using iPhoto). Finder says it was taken and edited on May 5. When I copy the photo back again to iPhoto it shows the right date again: April 11.
Any ideas? Thanks!
I'm running OS X Mountain Lion on an iMac 21,5" (late 2009).
