OK! Next time, I hope you can check your data backup carefully before you do any chance to it.
But, now, you should act carefully to restore all your wanted photos back:
- Do not save anything new on this camera any longer in case that anything new on it would rewrite your deleted photos.
- Insert this camera to your computer.
- Download a camera memory card data recovery freeware to your computer and restore all your deleted photos back successfully as soon as possible:
- Save and back up restored photos on another memory card or hard drive in case of data recovery failure.
