List of Exif tags (IFD0)

Embedded camera and exposure information that a digital camera puts in the header of the JPG files it creates

IDNameFormatComps 
0x010eImageDescription ascii string
Describes image. Two-byte character code such as Chinese/Korean/Japanese cannot be used.
0x010fMake ascii string
Shows manufacturer of digicam. In the Exif standard, this tag is optional, but it is mandatory for DCF.
0x0110Model ascii string
Shows model number of digicam. In the Exif standard, this tag is optional, but it is mandatory for DCF.
0x0112Orientation unsigned short1 The orientation of the camera relative to the scene, when the image was captured.
0x011aXResolution unsigned rational1 Display/Print resolution of image. Default value is 1/72inch, but it has no mean because personal computer doesn't use this value to display/print out.
0x011bYResolution unsigned rational1
0x0128ResolutionUnit unsigned short1 Unit of XResolution (0x011a)/YResolution (0x011b). '1' means no-unit, '2' means inch, '3' means centimeter. Default value is '2' (inch).
0x0131Software ascii string
Shows firmware (internal software of digicam) version number.
0x0132DateTime ascii string20 Date/Time of image was last modified. Data format is "YYYY:MM:DD HH:MM:SS"+0x00, total 20bytes. If clock has not set or digicam doesn't have clock, the field may be filled with spaces. In usual, it has the same value of DateTimeOriginal (0x9003)
0x013eWhitePoint unsigned rational2 Defines chromaticity of white point of the image. If the image uses CIE Standard Illumination D65 (known as international standard of 'daylight'), the values are '3127/10000,3290/10000'.
0x013fPrimaryChromaticities unsigned rational6 Defines chromaticity of the primaries of the image. If the image uses CCIR Recommendation 709 primaries, values are '640/1000,330/1000,300/1000,600/1000,150/1000,0/1000'.
0x0211YCbCrCoefficients unsigned rational3 When image format is YCbCr, this value shows a constant to translate it to RGB format. In usual, values are '0.299/0.587/0.114'.
0x0213YCbCrPositioning unsigned short1 When image format is YCbCr and uses 'Subsampling' (cropping of chroma data, all the digicam do that), defines the chroma sample point of subsampling pixel array. '1' means the center of pixel array, '2' means the datum point.
0x0214ReferenceBlackWhite unsigned rational6 Shows reference value of black point/white point. In case of YCbCr format, first 2 show black/white of Y, next 2 are Cb, last 2 are Cr. In case of RGB format, first 2 show black/white of R, next 2 are G, last 2 are B.
0x8298Copyright ascii string
Shows copyright information
0x8769ExifOffset unsigned long1 Offset to Exif Sub IFD
