Adding file information (Photoshop)

File information--also called metadata--is increasingly important in all types of publishing. Photoshop supports the information standard developed by the Newspaper Association of America (NAA) and the International Press Telecommunications Council (IPTC) to identify transmitted text and images. This standard includes entries for descriptions, keywords, categories, credits, and origins.

In Windows and Mac OS, you can add file information to files saved in Photoshop, Large Document Format (PSB), TIFF, JPEG, EPS, and PDF formats. In Mac OS, you can also add file information to files in other Photoshop-supported formats except GIF. The information you add is embedded in the file using XMP (eXtensible Metadata Platform). XMP provides Adobe applications and workflow partners with a common XML framework that standardizes the creation, processing, and interchange of document metadata across publishing workflows. When you save files from Photoshop that contain keywords, those keywords are not displayed in Adobe Acrobat's File Info dialog when the file is opened in Acrobat. For information on adding metadata to a file, see Working with the metadata palette and Adding metadata to files.

Note: It's possible to add metadata in ImageReady using the options in the Optimize palette. For more information, see Including image metadata (ImageReady).
