Description of Exif file format

Currently, most of new digicam use Exif file format to store images. This specification was made by JEIDA, but there is
no open document in internet. So I made tiny description about Exif from some of open documents that can get from
internet.
Add: Now we can get official document of Exif2.1 from PIMA's website.
ISO is now working to build DCF (Design rule for Camera File system) Specification. The entire digicam manufacturer
is moving to adopt it and their newest digicam already uses DCF. DCF defines whole file-system of digicam; directory
structure, file naming method, character set and file format etc. The file format of DCF is based on Exif2.1 specification.
I believe this document is basically based on Exif2.1/DCF specification, if you have information about 'unknown' item or

What is Exif file format?

Basically, Exif file format is the same as JPEG file format. Exif inserts some of image/digicam information data and
thumbnail image to JPEG in conformity to JPEG specification. Therefore you can view Exif format image files by JPEG
compliant Internet browser/Picture viewer/Photo retouch software etc. as a usual JPEG image files.

JPEG format and Marker

Every JPEG file starts from binary value '0xFFD8', ends by binary value '0xFFD9'. There are several binary 0xFFXX
data in JPEG data, they are called as "Marker", and it means the period of JPEG information data. 0xFFD8 means SOI
(Start of image), 0xFFD9 means EOI(End of image). These two special Markers have no data following, the other
Markers have data with it. Basic format of Marker is below.
0xFF+Marker Number(1 byte)+Data size(2 bytes)+Data(n bytes)
Data size(2 Bytes) has "Motorola" byte align, starts from bigger digits. Please notice that "Data" contains Data size
descriptor, if there is a Marker like this;
FF C1 00 0C
It means this Marker(0xFFC1) has 0x000C(equal 12)bytes of data. But the data size '12' includes "Data size" descriptor,
it follows only 10 bytes of data after 0x000C.

Marker used by Exif

The marker 0xFFE0~0xFFEF is named "Application Marker", not necessary for decoding JPEG image. They are used
by user application. For example, older olympus/canon/casio/agfa digicam use JFIF(JPEG File Interchange Format) for
storing images. JFIF uses APP0(0xFFE0) Marker for inserting digicam configuration data and thumbnail image.
Also Exif uses an Application Marker for inserting data, but Exif uses APP1(0xFFE1) Marker to avoid a conflict with
JFIF format. Every Exif file formats starts from this format;
SOI Marker APP1 Marker APP1 Data
FFD8

FFE1

Other Marker

SSSS 457869660000 TTTT...... FFXX SSSS DDDD......

It starts from SOI(0xFFD8) Marker, so it's a JPEG file. Then APP1 Marker follows immediately. All the data of Exif are
stored in this APP1 data area. The part of "SSSS" on upper table means the size of APP1 data area (Exif data area).
Please notice that the size "SSSS" includes the size of descriptor itself also.
After the "SSSS", APP1 data starts. The first part is a special data to identify whether Exif or not, ASCII character "Exif"
and 2bytes of 0x00 are used.
After the APP1 Marker area, the other JPEG Markers follows.

Exif data structure

Roughly structure of Exif data (APP1) is shown as below. This is a case of "Intel" byte aligns and it contains JPEG
format thumbnail. As described above, Exif data is starts from ASCII character "Exif" and 2bytes of 0x00, and then Exif
data follows. Exif uses TIFF format to store data. For more details of TIFF format, please refer to "TIFF6.0 specification".

Structure of TIFF header

First 8bytes of TIFF format are TIFF header. First 2bytes defines byte align of TIFF data. If it is 0x4949="I I", it means
"Intel" type byte align. If it is 0x4d4d="MM", it means "Motorola" type byte align. For example, value '305,419,896' is
noted as 0x12345678 by sixteenth system. At the Motorola align, it is stored as 0x12,0x34,0x56,0x78. If it's Intel align, it
is stored as 0x78,0x56,0x34,0x12. It seems that most of digicam uses Intel align. Ricoh uses Motorola align. Sony uses
Intel align except D700. Kodak DC200/210/240 use Motorola aligns, but DC220/260 use Intel aligns though they are
using PowerPC! Therefore when we need the value of Exif data, we MUST check byte align every time. Though JPEG
data uses Motorola align only, Exif allows both alignments. I can't understand why Exif didn't fix a byte align to
Motorola.
Next 2bytes are always 2bytes-length value of 0x002A. If the data uses Intel align, next 2bytes are "0x2a,0x00". If it uses
Motorola, they are "0x00,0x2a". The last 4bytes of TIFF header are an offset to the first IFD(Image File Directory,
described in next chapter). Includes this offset, all the offset value used in TIFF format counts offset bytes from the first
of TIFF header("I I" or "MM"). Usually the first IFD starts immediately next to TIFF header, so this offset has value
'0x00000008'.

IFD : Image file directory

Next to TIFF header, there is the first IFD:Image File Directory. It contains image information data. At the chart below,
the first 2bytes('EEEE') means the number of directory entry contains in this IFD. Then directory entry (12bytes per
entry) follows. After last directory entry, there is a 4bytes of data('LLLLLLLL' at the chart), it means an offset to next
IFD. If its value is '0x00000000', it means this is the last IFD and there is no linked IFD.

Offset to next IFD

'TTTT'(2bytes) of above chart is Tag number, this shows a kind of data. 'ffff'(2bytes) is data format,
'NNNNNNNN'(4bytes) is number of components. 'DDDDDDDD'(4bytes) contains a data value or offset to data value.

Data format
Data format ('ffff' at the above chart) is defined as below. "rational" means a fractional value, it contains 2-signed/
unsigned long integer values, and the first represents the numerator, and the second, the denominator.

You can get the total data byte length by multiplies a 'bytes/components' value (see above chart) by number of
components stored 'NNNNNNNN' area. If total data length is less than 4bytes, 'DDDDDDDD' contains the value of that
Tag. If its size is over 4bytes, 'DDDDDDDD' contains the offset to data stored address.

IFD data structure

At Exif format, the first IFD is IFD0(IFD of main image), then it links to IFD1(IFD of thumbnail image) and IFD link is
terminated. But IFD0/IFD1 doesn't contain any digicam's information such as shutter speed, focal length etc. IFD0
always contains special Tag Exif Offset (0x8769), it shows an offset to Exif SubIFD. Exif SubIFD is IFD formatted data
also, it contains digicam's information.
In case of Extended Exif format (Exif2.1/DCF), Exif SubIFD contains special Tag Exif Interoperability Offset
(0xa005). It also points to the Interoperability IFD. By the DCF specification, this tag is mandatory and both SubIFD
(main image IFD) and IFD1 (thumbnail image IFD) may have Interoperability IFD. In usual, only main image have this
tag.
And some of digicam uses IFD data format for Makernote; Maker-specific magic number area. It's very hard to decision
whether makernote is IFD format or not, be careful to coding program. See Appendix for information of Makernote.

0020: 00 00 40 00 00 00 48 00-00 00 01 00 00 00
If the first part of TIFF data is above, it can read as;

The first 2bytes are "I I", byte align is 'Intel'.

Address 0x0004~0x0007 is 0x08000000, IFD0 starts from address '0x0008'
Address 0x0008~0x0009 is 0x0200, number of directory entry of IFD0 is '2'.
Address 0x000a~0x000b is 0x1A01, it means this is an XResolution(0x011A) Tag, it contains a horizontal

resolution of image.
Address 0x000c~0x000d is 0x0500, format of this value is unsigned rational(0x0005).
Address 0x000e~0x0011 is 0x01000000, number of components is '1'. Unsigned rational's data size is 8bytes/
components, so total data length is 1x8=8bytes.
Total data length is larger than 4bytes, so next 4bytes contains an offset to data.
Address 0x0012~0x0015 is 0x26000000, XResolution data is stored to address 0x0026
Address 0x0026~0x0029 is 0x48000000, numerator is 72, address 0x002a~0x002d is 0x0100000000,
denominator is '1'. So the value of XResoultion is 72/1.
Address0x0016~0x0017 is 0x6987, next Tag is ExifOffset(0x8769). Its value is an offset to Exif SubIFD
Data format is 0x0004, unsigned long integer.
This Tag has one component. Unsigned long integer's data size is 4bytes/components, so total data size is 4bytes.
Total data size is equal to 4bytes, next 4bytes contains the value of Exif SubIFD offset.
Address 0x001e~0x0021 is 0x11020000, Exif SubIFD starts from address '0x0211'.
This is the last directory entry, next 4bytes shows an offset to next IFD.
Address 0x0022~0x0025 is 0x40000000, next IFD starts from address '0x0040'

Thumbnail image
Exif format contains thumbnail of image (except Ricoh RDC-300Z). Usually it is located next to the IFD1. There are 3
formats for thumbnails; JPEG format(JPEG uses YCbCr), RGB TIFF format, YCbCr TIFF format. It seems that JPEG
format and 160x120 pixels of size are recommended thumbnail format for Exif2.1 or later. By the DCF specification,
thumbnail image MUST use JPEG format and image size is fixed to 160x120 pixels.
JPEG format thumbnail
If the value of Compression(0x0103) Tag in IFD1 is '6', thumbnail image format is JPEG. Most of Exif image uses JPEG
format for thumbnail. In that case, you can get offset of thumbnail from JpegIFOffset(0x0201) Tag in IFD1, size of
thumbnail from JpegIFByteCount(0x0202) Tag. Data format is ordinary JPEG format, starts from 0xFFD8 and ends by
0xFFD9.
TIFF format thumbnail
If the value of Compression(0x0103) Tag in IFD1 is '1', thumbnail image format is no compression(called TIFF image).
Start point of thumbnail data is StripOffset(0x0111) Tag, size of thumbnail is the sum of StripByteCounts(0x0117) Tag.
If thumbnail uses no compression and PhotometricInterpretation(0x0106)Tag in IFD1 has a value '2', thumbnail uses
RGB format. In that case, you can see thumbnail image by simply copy data to computer's RGB format(such as BMP
format, or copy to VRAM directory). Kodak DC-210/220/260 uses this format. Be mention that at TIFF stores pixel data
as 'RGB' order, but BMP stores 'BGR' order.
If that tag has a value '6', thumbnail uses YCbCr format. If you want to see thumbnail, you must convert it to RGB. Ricoh
RDC4200/4300, Fuji DS-7/300 and DX-5/7/9 use this format(newer RDC5000/MX-X00 series use JPEG). Next section
is brief description to conversion of Fuji DS's thumbnail. For more details, refer to TIFF6.0 specification.
At DX-5/7/9, YCbCrSubsampling(0x0212) has values of '2,1', PlanarConfiguration(0x011c) has a value '1'. So the data
align of this image is below.
Y(0,0),Y(1,0),Cb(0,0),Cr(0,0), Y(2,0),Y(3,0),Cb(2,0),Cr(3.0), Y(4,0),Y(5,0),Cb(4,0),Cr(4,0). . . .
The numeric in parenthesis is pixel coordinates. DX series' YCbCrCoefficients(0x0211) has values '0.299/0.587/0.114',

Exif file format

ReferenceBlackWhite(0x0214) has values '0,255,128,255,128,255'. Therefore to convert from Y/Cb/Cr to RGB is;
B(0,0)=(Cb-128)*(2-0.114*2)+Y(0,0)
R(0,0)=(Cr-128)*(2-0.299*2)+Y(0,0)
G(0,0)=(Y(0,0)-0.114*B(0,0)-0.299*R(0,0))/0.587
Horizontal subsampling is a value '2', so you can calculate B(1,0)/R(1,0)/G(1,0) by using the Y(1,0) and Cr(0,0)/Cb(0,0).
Repeat this conversion by value of ImageWidth(0x0100) and ImageLength(0x0101).

Some of digicam can take 2~30 pictures per second, but

DateTime/DateTimeOriginal/DateTimeDigitized tag can't
record the sub-second time. SubsecTime tag is used to
record it.
For example, DateTimeOriginal = "1996:09:01 09:15:30",
SubSecTimeOriginal = "130", Combined original time is
"1996:09:01 09:15:30.130"

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........

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.
