 # 34665	8769	Exif IFD	 A pointer to the Exif IFD. Exif IFD is a set of tags for recording Exif-specific attribute information. It is pointed to by the offset from the TIFF header (Value Offset) indicated by an Exif private tag value. An Exif IFD has the same structure as that of the IFD specified in TIFF. Ordinarily, however, it does not contain image data as in the case of TIFF.
