Things You'll Need
Instructions
Turn your Canon camera off and remove the memory card as soon as you realize you have accidently deleted the picture from the card.
Turn your home computer on and connect to the Internet. Pay for and download the Canon Photo Recovery software. (See References.) Once the program is downloaded, open the program.
Insert the memory card into the card reader on your computer or into an external card reader that is connected to your computer.
Click "File" and select "Scan" from the drop-down menu. Select the icon that represents the memory card you have inserted into the card reader and click "OK" in the bottom right of the window.
Click the recovered picture from the new window that will appear after the Canon Photo Recovery program has completed its scan. Save the recovered picture to your computer's hard drive.
