ExifyMe
XtraSimplicity
ExifyMe helps to simplify some of the functionality offered in the command-line application, Exiftool, by offering an easy to use GUI. You simply select the modified image, and the original, unmodified image, and click Restore - and the EXIF data of the modified image will automatically be restored to what it originally was, and a backup file (saved as .original) is automatically created, so as to not cause any data loss.
