What I'm just not getting is that they all start with Tag 0 or Tag 1 - suggesting that these tags are within the MakerNotes blob of data. This site has quite a large number of Camera Specific tags for various Canon models. It does seem as though different Cannon models have a different MakerNotes. Also it supports to show the MakerNote information of wide range manufacturer device. It supports EXIF Specification 2.3 and displays the exif data in your photo.
Downloadable exif data viewer code#
The code snippet above returned about 7600 bytes, here is a sample of the first few: Exif Data Viewer is a free program to display exif information of image. However looking at the data returned from the code snippet above, this is not making sense Stipulation regarding the order or position of tag value (Value) recording.

Note that field Interoperability shall be recorded in sequence starting from the smallest tag number. For example, in bigĮndian format, if the type is SHORT and the value is 1, it is recorded as 00010000.H. Stored in the 4-byte area starting from the left, i.e., from the lower end of the byte offset area. If the value is smaller than 4 bytes, the value is InĬases where the value fits in 4 bytes, the value itself is recorded. This tag records the offset from the start of the TIFF header to the position where the value itself is recorded. Value of SHORT (16 bits), for example, the count is '1' even though it is 2 bytes. It should be noted carefully that the count is not the sum of the bytes. The first SLONG is the numerator and the second SLONG is the The first LONG is the numerator and the second LONG expresses theħ = UNDEFINED An 8-bit byte that can take any value depending on the field definition,ĩ = SLONG A 32-bit (4-byte) signed integer (2's complement notation),ġ0 = SRATIONAL Two SLONGs. The final byte is terminated with NULL.,ģ = SHORT A 16-bit (2-byte) unsigned integer,Ĥ = LONG A 32-bit (4-byte) unsigned integer,ĥ = RATIONAL Two LONGs. The tag numbers in the Exif 0th IFD and 1st IFDĪre all the same as the TIFF tag numbers.Ģ = ASCII An 8-bit byte containing one 7-bit ASCII code. 6.0.Įach tag is assigned a unique 2-byte number to identify the field. 6.0.Įach of the 12-byte field Interoperability consists of the following four elements respectively.Įach element is explained briefly below. The IFD used in this standard consists of a 2-byte count (number of fields), 12-byte field Interoperability arrays, andĤ-byte offset to the next IFD, in conformance with TIFF Rev.
