| Make | Format | Header | Endian 1) | Offsets 2) | Ref | Remarks |
|---|---|---|---|---|---|---|
| Canon | IFD | None | [2] | Some CR2 images have a non-zero next-IFD pointer | ||
| CASIO | IFD | None | [4] | |||
| CASIO | IFD, at offset 6 | "QVC\0\0\0" | Big-endian (MM) | Relative to the beginning of the makernote | [4] | |
| FUJI | IFD, usually at offset 12 | Starts with the string "FUJI" and a 4 byte pointer to the IFD | Little-endian (II) | Relative to the beginning of the makernote | [1] | Exif data uses big-endian (MM) byte order |
| Minolta, KONICA MINOLTA | IFD | None | [5] | Camera settings tag is encoded in big-endian (MM) style, regardless of the encoding style of the Exif data | ||
| NIKON | IFD | None | [3] | Models using this makernote include E990, D1 | ||
| NIKON | IFD, at offset 8 | "Nikon\0" followed by two bytes of unknown meaning | [1] | Models using this makernote include E700, E800, E900, E900S, E910, E950 | ||
| NIKON | IFD, usually at offset 18 | "Nikon\0" followed by 4 bytes which look like a version code and a TIFF header | From makernote TIFF header | Relative to the start of the makernote TIFF header | Models using this makernote include E5400, SQ, D2H, D70, D100, D200. Makernote IFD of the D200 has no next-IFD pointer. (Is this a bug?) | |
| OLYMPUS | IFD, at offset 8 | "OLYMP\0" followed by two bytes of unknown meaning | [1] | |||
| OLYMPUS | IFD, at offset 12 | "OLYMPUS\0II" followed by two bytes of unknown meaning | Relative to the beginning of the makernote | |||
| Panasonic | IFD without a next-IFD pointer at offset 12 | "Panasonic\0\0\0" | [8] | |||
| PENTAX | IFD at offset 6 | "AOC\0" followed by two bytes of unknown meaning | [11] | |||
| SAMSUNG | IFD | None | Relative to the beginning of the makernote | |||
| Sanyo | IFD | - | - | - | [6] | Not supported by Exiv2 yet |
| SIGMA, FOVEON | IFD, at offset 10 | "SIGMA\0\0\0" or "FOVEON\0\0" followed by two bytes of unknown meaning | [7] | |||
| SONY | IFD without a next-IFD pointer at offset 12 | "SONY DSC \0\0\0" | Seen in Jpeg images, e.g., from DSC-W7, DSC-R1 | |||
| SONY | IFD | None | Seen in SR2 images, e.g., from DSC-R1 |
1) If not specified, the byte order of the Exif data is applicable.
2) If not specified, offsets are relative to the start of the TIFF header.
