Metadata is now being used extensively to add nonimage data to files, and such data can be anything from copyright, author, color space, or keywords to comments relating to workflow or even a history of the steps taken to create a file. The information can be used to track or find files locally, or over a network.
The metadata can be stored in the file if the format supports it; otherwise, it can be stored in an XMP sidecar file, as is the case with raw files (DNG raw files being the exception). You can view metadata in the Metadata panel for any file by selecting it in the Bridge window. Furthermore, the fields shown in the Metadata panel can be selected in Preferences ^ Metadata.
NOTE If you select more than one file, only metadata that is common to the selected files is shown.
You have three ways of working with metadata in Bridge. You can use the Metadata panel (View ^ Metadata Panel), the Keywords panel (View ^ Keywords Panel), or the File Info dialog box (File ^ File Info). All three let you enter new metadata; the Metadata and File Info panels also let you append or replace existing metadata.
To append or replace metadata, you must first create a template. You can do so in the File Info panel by entering text and then choosing Save Metadata Template from the dialog box menu (to access the menu, click the round button at the top right of the dialog box). After a template is saved, you can append or replace the existing metadata from the Metadata panel menu, the Advanced screen of the File Info dialog box, or the Tools menu.
You can append and replace metadata from single or multiple files. Simply select the file(s) in the Bridge window and then use any one of the preceding means to access the append/replace commands.
You cannot edit the metadata for File Properties or Camera Data (EXIF) in the or File Info panel. EXIF stands for Exchangeable Image File Format.
