EXIF it is metadata that is added to an image or other media file during its creation. Used to store date, time, camera number, GPS data, author name, and so on. It can be used in a photo lab when printing a photo, as well as to protect copyright for an image.

Where does EXIF ​​come from

Cameras add EXIF ​​to the file as it is created. Parameters such as author name, copyright, and comment margin can be manually set via the camera menu. In EXIF, when processing a file, data can be added or deleted. Programs like Lightroom can clear the EXIF ​​data field altogether when converting a file between formats. The camera usually records the following data:

  • File creation date and time
  • Authorship (both author name and copyright)
  • Serial number of the camera
  • ISO
  • Exposure data (excerpt, diaphragm)
  • Object distance
  • Focal length lens
  • Matrix size
  • Image size
  • Coordinates

and many others.
