/**
 * 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.
 * <pre><code>
 * :0000: 4E 69 6B 6F 6E 00 01 00-05 00 02 00 02 00 06 00 Nikon...........
 * :0010: 00 00 EC 02 00 00 03 00-03 00 01 00 00 00 06 00 ................
