We rely on the Perl library to write copyright information into the Exif header of our JPEGs and into DNG files. We also use it to read Exif header information. Our Services page includes a blow-by-blow account of building an OS X contextual menu service using ExifTool and we've added a Services Request form so you can request our help with your own software development.
We've explained how to reset the capture time in your images with ExifTool in Spring Back After The Fact. And we've written about using the tool in Copyrighter Pro to add copyright information to your images, as well. Most recently, we published Using Exiftool as an Image Organizer.
It's really the Swiss Army knife of Exif data.
