I was processing some RAW photos taken with a Nikon D300 in NEF format. I accidentally (read brain went numb) did a "save" in lieu of a "save as" and POOF, my NEF "photo" in the directory turned black and was gone. The "pixel size" at the top left of the thumbnail was set to 0,0 for size! Is this a fatal flaw in allowing a "save" action to a NEF file?? Just wondering.
