You can call this operation to query the exchangeable image file (Exif) information of an image. Exif specifies the format of images used by digital cameras and records the attribute information and shooting data of digital images. The Exif information includes various shooting conditions such as the aperture, shutter, white balance, ISO, focal length, and the shooting date and time. It also includes the brand name and model of the camera, color code, sound recorded during shooting, GPS data, and thumbnails.


To call this operation, you must have the GetObject permission. If the object does not exist, the following errors may be returned:

  • If you have the ListBucket permission on the bucket where the object resides, KS3 returns a 404 error.
  • If you do not have the ListBucket permission on the bucket, KS3 returns a 403 error.
