Went to print a photo that a friend sent to me and that I hd edited to tweak it for her and discovered that the file had been corrupted. Red highlights were showing in the light areas of the photo and blue highlights were showing in the shadow areas. I seems to be correctable but it takes a great deal of fiddling to repair them. At least half of my photo in all of my project libraries were affected. I edit in Aperture. Anyone out there hear of anything like this happening? I am Baffled.
