When I export a picture in iPhoto as a jpg and then open the file in the latest version of GraphicConverter, I get the following error message (from GC): "The EXIF data of the file "img4.jpg" is corrupted (it contains two orientation tags). So, only one tag will be used (depending on the prefs)."
Now, is iPhoto actually corrupting the EXIF data or is GraphicConverter reading it incorrectly?
BTW, the iPhoto pictures originally came from my Canon Digital Elph.
