24/**
25 * Fujifilm's digicam added the MakerNote tag from the Year2000's model (e.g.Finepix1400,
26 * Finepix4700). It uses IFD format and start from ASCII character 'FUJIFILM', and next 4
27 * bytes(value 0x000c) points the offset to first IFD entry. Example of actual data
28 * structure is shown below.
29 *
30 * :0000: 46 55 4A 49 46 49 4C 4D-0C 00 00 00 0F 00 00 00 :0000: FUJIFILM........
31 * :0010: 07 00 04 00 00 00 30 31-33 30 00 10 02 00 08 00 :0010: ......0130......
32 *
33 * There are two big differences to the other manufacturers.
34 * - Fujifilm's Exif data uses Motorola align, but MakerNote ignores it and uses Intel
35 * align.
36 * - The other manufacturer's MakerNote counts the "offset to data" from the first byte
37 * of TIFF header (same as the other IFD), but Fujifilm counts it from the first byte
38 * of MakerNote itself.
