The exif data says "manual exposure".....should be AE, no?
....try a factory defaults reset ......try rotating the "Photography Mode Selector" (main dial on top) to SET-UP ....then cycle through the list to the last choice..."RESET" and hit OK. (check your manual, I'm not sure)
could you tell on the lcd that everything was blown out? if not, perhaps it is a writing problem..
hopeful just some setting got bumped...otherwise it's back to the factory for that one....
