Appendix 1: MakerNote of Olympus Digicams

The data below is analyzed at Olympus D450Z(C-920Z) by Peter Esherick.

MakerNote of Olympus Digicam starts from ASCII string "OLYMP". Data format is the same as IFD, but it starts from offset 0x07. Example of actual data structure is shown below.

Appendix 3: MakerNote of Casio

Casio started to use Exif format from QV2000/QV8000. Casio's MakerNote format is the same as usual IFD (e.g. IFD0, SubIFD0). Example of actual data structure is shown below.

Appendix 4: MakerNote of Fujifilm

Fujifilm's digicam added the MakerNote tag from the Year2000's model (e.g.Finepix1400,Finepix4700). It uses IFD format and start from ASCII character 'FUJIFILM', and next 4 bytes(value 0x000c) points the offset to first IFD entry. Example of actual data structure is shown below.

:0000: 46 55 4A 49 46 49 4C 4D-0C 00 00 00 0F 00 00 00 :0000: FUJIFILM........:0010: 07 00 04 00 00 00 30 31-33 30 00 10 02 00 08 00 :0010: ......0130......

There are two big differences to the other manufacturers.

Fujifilm's Exif data uses Motorola align, but MakerNote ignores it and uses Intel align.

The other manufacturer's MakerNote counts the "offset to data" from the first byte of TIFF header (same as the other IFD), but Fujifilm counts it from the first byte of MakerNote itself.

I think it's a BUG, but it can't be helped now... The data below is analyzed at Fujifilm FinePix4900Z.

Appendix 5: MakerNote of Canon

The data below was primarily analysed by David Burren and the master version of this information is available at: http://www.burren.cx/david/canon.html. Please send any updates to David.
This document is based on his Rev.1.11(2001/01/30) of document.

Canon's MakerNote data is in IFD format, starting at offset 0.

Some of these tags and fields are only produced on cameras such as the EOS D30, but (to current observation) all this is valid for all Canon digicams (at least since the A50). If the tag is not found, or is shorter than shown here, it simply means that data is not supported by that camera.
