Exifer is a nearly free software with which you can manage the metadata (EXIF/IPTC) of pictures taken by digital cameras. Because many image processing software destroys this metadata when saving such files, the idea was to create a backup of the metadata before editing it in any software, and then, after that to restore it back into the processed file. With Exifer you can do this very easily.
