An Overview of Working with Metadata
Information about your photos, including the types of adjustments applied, information recorded
by the camera, and descriptive information about the photos, is called metadata. In Aperture, you
work with three types of metadata.
The rst type of metadata is called Exchangeable Image File (EXIF) data. EXIF metadata is
information recorded by the camera and stored in the image le at the time it was shot, such
as shutter speed, f-stop, the time the photo was captured, the camera model, and GPS data (for
cameras that support it).
The second type of metadata is data you apply to identify and track photos within Aperture,
such as a version name, color labels, ags, keywords, when the photo was imported, the types of
adjustments applied to it, and how and where it was published.
The third type of metadata is called International Press Telecommunications Council (IPTC) data.
IPTC metadata is standardized data used by photographers and media organizations to embed
keywords, captions, copyright notices, and other information in the image les themselves. You
can view and modify IPTC metadata in Aperture.
Note: For more information about working with GPS data in Aperture, see An Overview of
Places on page 203.
