Opened up Bridge and edited multiple images successfully. Went back later to edit a few more and while some of the images show in the Bridge folder, some just have the number.nef. Chalked it up to a corrupt file, but the next day they opened fine again, and I edited two more. Today, wanting to finish my edits, I am back to a number.nef again. Anyone have any ideas as to how I can retrieve these files. If they were session shots, I would have immediately duplicated the folder, but these were just for fun.
