Recovering lost photos

Whoops! I accidentally deleted some pics from my digital camera this morning. I realised as soon as I hit the delete button I had done the wrong thing. I have a utility to restore files I have deleted from my computer, but what about the camera? An online search yielded a big array of utilities, so I downloaded and tried one called Zero Assumption Digital Image Recovery. It took around half an hour to scan my camera, during which time I could do nothing else, and then said it could find no images to recover. What a dud! Next I tried Recuva. What a joy! Simple to use, fast (it took only a few minutes to scan the camera), and gave me a thumbnail of every image it could bring back, including many I would have thought were long gone. The one I wanted was there, and took only seconds to restore to my computer. Once again I'm a happy chappie.
