Using a reliable data recovery application, you can still get back the photos deleted from your SD card.
When you save a file to a disk, you store not only its actual data but also the information about it in different places. What happens when your photos get deleted is that the photos are marked as deleted and the space where they are stored becomes available for new data or photos.
However, until the storage space is overwritten by new files, they are still on your SD card and can be retrieved. What you need to do now is to avoid saving any new photos to the SD card and start data recovery right away.
