Things You'll Need
Instructions
Do not take any more pictures on the memory stick once you realize you have deleted a photograph that you wanted to keep.
Attach your camera to the computer with the USB cable. Make sure that your memory stick is installed in the camera. Look in "My Computer" and determine what letter drive your camera is.
Download the picture recovery software from Card Recovery using the link in the resources section.
Start the Card Recovery program by going to Start-->Programs and selecting the Card Recovery software. Click "Next" to choose the letter drive of your camera, and to indicate where you would like your recovered pictures to be saved.
Click "Next" to begin the scan of your camera.
Select "Next" when the scan is complete to preview the recovered pictures. If none show up, the software was unable to recover your photos.
Save your recovered photographs to the indicated location that you chose earlier.
