Final answer:
EXIF data in JPEGs includes metadata for mapping and identifying photos to a specific device or camera.
Step-by-step explanation:
EXIF or Exchangeable Image Format data often includes metadata, allowing the images to be mapped and identified to a specific device or type of camera. Metadata in EXIF data can include information such as the camera make and model, date and time the photo was taken, exposure settings, and GPS coordinates.
This metadata is important for organizing and categorizing photos, as well as for forensic purposes in identifying the source of an image. It can also be used to analyze trends and patterns in photography.
Overall, EXIF data, including metadata, enhances the browsing, searching, and understanding of digital images.
