In this kind of case, you can very often recover lost or deleted pictures from a camera memory card or USB Memory stick. Depending on camera models and how they reformat, in many cases you can even also recover deleted photos after a card format.

In general, in order to increase the chances of being able to recover pictures after they have been deleted you must not save any new photos, files or data to it.

When you delete pictures (or any files) from a memory card or USB memory device the data itself isn’t deleted, just the file system pointers that says where the data for those files is located. The area where the deleted picture data was stored is also now marked as free space so it is available to the system for any new files to be written there instead.

If and when that happens, then it is too late to recover your deleted pictures so it is very, very important that new pictures or files aren’t saved to the memory card in the meantime.

One of the easiest ways to see if your deleted pictures can be recovered is to try some photo recovery software.

One tip is to try a demo version of a commercial product that will scan the memory card for deleted pictures and show you exactly what pictures can be recovered. At least that will show you if you can recover the deleted pictures or if it’s too late already.
