I get asked about recovering deleted photos about once a month and have never made a placeholder for the info here on RDN. These two utilities from CG Security - TestDisk and PhotoRec - will get you out of most disk and file jams (you can even recover lost partitions and/or make non-booting disks bootable again) and recover your over/under-exposed, red-eye-glaring and blurry snaps that your camera/machine accidentally deleted somehow without you touching it or even being powered on.

Both are open source and run on pretty much any machine you have.
