What I'd do.
Unless you have a Linux machine, boot up a Linux live USB on your laptop.
Mount your windows c:
Install ntfs-3g and mount it to /mnt
Use dd to make an image of the sdcard (assuming it's sdb);
sudo dd if=/dev/sdb of=/mnt/sdcard.img bs=1M
Eject the sdcard;
sudo eject /dev/sdb
Install photorec and point it to the image file. To see what you can recover. Recover files to /mnt/somediryoumake .
Good luck!
