Mac only: You know that sinking feeling you get when you accidentally delete your photos or reformat your camera's memory card without first removing the pictures on it? Reach for Exif Untrasher instead of antacids and rescue those pics from annihilation.
Use Exif Untrasher to mount the memory card on your Mac, just as if it were a regular volume. Choose a destination folder for the rescued images, and let the app do its thing. It's not a 100% foolproof way to recover pictures you've accidentally deleted or overwritten, but since it doesn't tamper with your card in any way, you've got nothing to lose.
To take this app for a test drive, I batch deleted a bunch of photos (that I had already backed up) from my camera's memory card, then reformatted it. I then plugged the card into my card reader, mounted the volume, and Exif Untrasher recovered everything but the MOV file, all in under a minute.
One important note: For now, this app can only recover JPG images, so if you're camera saves in the RAW format, you're out of luck. Exif Unitrasher 1.4.3 is a free download and works on Mac OS X 10.3 or higher. If you're running a lower version of Mac OS X, then be sure to snag Exif Untrasher's earlier 1.3.6 version instead. If photos aren't your only problem, check out our previous guide to recovering deleted files with free software (with suggestions for Windows, Mac and Linux).
