Exiv2 C++ library

Fast read and write access to the Exif, IPTC and XMP metadata of an image
Easy to use and extensively documented C++ API
Conversions of Exif and IPTC metadata to XMP and vice versa
Smart IPTC implementation that does not affect data that programs like Photoshop store in the same image segment

Exif Makernote support:

Makernote tags can be read and written just like any other metadata
Sophisticated write algorithm avoids corrupting the Makernote
Set and delete methods for ICC Profiles
Set and delete methods for Exif thumbnails
The exiv2 command-line program provides a rich scripting interface for image metadata
