You can also use the following special formatting syntax to print EXIF information contained in the file:

   %[EXIF:tag]

Choose tag from the following:

   *  (print all EXIF tags, in keyword=data format)
   !  (print all EXIF tags, in tag_number data format)
   #hhhh (print data for EXIF tag #hhhh)
