  /**
   * Describes tags specific to Nikon (type 1) cameras.  Type-1 is for E-Series cameras prior to (not including) E990.
   *
   * There are 3 formats of Nikon's Makernote. Makernote of E700/E800/E900/E900S/E910/E950
   * starts from ASCII string "Nikon". Data format is the same as IFD, but it starts from
   * offset 0x08. This is the same as Olympus except start string. Example of actual data
   * structure is shown below.
