While it seems that an article here is a bit of preaching to the converted, the need for metadata adds is apparent to the photographing public. 91% of our responding readers do add metadata to their photos with copyright info leading the list at 77%. With the addition of a caption and a headline along with keywords, it becomes powerful “Google Juice.” Photofocus readers weigh inĪ recent poll of Photofocus readers skews totally in the opposite direction. Metadata added to a photo is more than an announcement of the creator’s name, contact info, and copyright. Current data shows that 85% of all of the photographs online have no metadata at all. IPTC can hold copyright, usage and contact info for a photo, but only if it’s added to the photo. Metadata contains all of the written information about a photograph.
This incorporated IPTC data into XMP which is used largely with Adobe’s Lightroom, Bridge, and Photoshop as well as some other imaging programs. In 2004 Adobe, IPTC and the IDEAlliance worked together to produce the IPTC Core Schema for XMP. XMP was introduced by Adobe in 2001 along with the Camera Raw plug-in. The creator, address, country, copyright, usage, caption, headline, keywords, and much more are part of the IPTC protocol. Today IPTC has evolved into the standard for adding vital information to a photograph or video. IPTC was originally developed as the method for adding captions and credits to wire photos for newspapers and early television newscasts. These include IPTC ( International Press Telecommunications Council) and XMP (e Xtensible Metadata Platform).
Other forms of metadata are added by the photographer. EXIF metadata is added by the camera immediately after the pixels are recorded. The first is the EXIF ( Exhangeable Image File format) which adds the camera, manufacturer, focal length, GPS, exposure, and sometimes, depending on the camera, the owner’s name and copyright. Metadata is information about a photograph that is added after the pixels are captured.
