Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
You can leverage the metadata information attached to the image files to help you organize and manage your photo library. Much of the metadata, such as capture date, exposure time, focal length and other camera settings, is generated by your camera, but you can also add your own metadata to make it easier to search and sort your catalog. In fact, you did just that when you applied keywords, ratings, and color labels to your images. In addition, Lightroom supports the information standards evolved by the International Press Telecommunications Council (IPTC), which includes entries for descriptions, keywords, categories, credits, and origins.
You can use the Metadata panel in the right panel group to inspect or edit the metadata attached to a selected image.
