Data Recovery - Do You Need Recover Deleted Photo?
When and what you delete is a personal matter
When and what you delete is a personal matter. Doing it in camera is the most decisive and fully committed way, but if you have any doubts consider leaving it until the next stage - when the images are on the computer.
If the spring-cleaning urge is too strong for you to resist and you feel you really must delete image files burn them to DVD to store them and then delete them from your hard drive.
