Exiv2 is a C++ library and a command line utility for managing image metadata. It provides fast and easy read and write access to the Exif, IPTC, and XMP metadata of images in many formats. The Exiv2 command line utility prints Exif, IPTC, and XMP metadata including Makernote tags in various formats, adjusts Exif timestamps, renames images according to the Exif timestamp, extracts and inserts Exif, IPTC, and XMP metadata and JPEG comments, or deletes the thumbnail or a specific type of metadata from an image.
JCap is a Java application for adding captions and descriptions to your digital photograph collection and includes a search dialog for finding photos later. It is completely self-contained; it doesn't require a separate database application or Web server to run. Captions, descriptions, and keywords are stored in plain text files in the same folder as the images they describe and can be read by any application that can read text files. The primary goals are: to help you find photos later, to help share photos with others, and to be able to read photo captions and descriptions thirty years from now on whatever computer you happen to have at the time.
OrbySPV (Sequential Panoramic Viewer) gives you the ability to create highly interactive virtual tours, similiar to the Google Maps Street View, using your own panaromic images. The Orby experience is not like the other virtual tours that you may have seen around the Web, where you stand in one spot and look around in a static 360 degree bubble. Orby has that ability, but instead of standing in a single position, you can actually walk around in the captured environment, stop at any position, and zoom and rotate as much as you want.
