When you capture an image, EXIF metadata is automatically populated by the body. You can add custom IPTC metadata in the Metadata tab. To open the Metadata tab, go to the View menu and select Metadata.
You can leave the IPTC field empty, or you can fill in one or more fields with your custom data. If you are Batch shooting, putting a token such as @BID or @JOB will embed that batch data into the IPTC field. This data stored in the EXIF and IPTC fields are searchable from within the image browser.
