ImageDescription   string Describes the image.
Make   string The manufacturer of the recording equipment. This is the manufacturer of the DSC, scanner, video digitizer or other
equipment that generated the image.
Model   string Shows model number of digicam
Orientation   integer The orientation of the camera relative to the scene, when the image was captured
1 top left side
2 top right side
3 bottom right side
4 bottom left side
5 left side top
6 right side top
7 right side bottom
8 left side bottom
XResolution   double Resolution of image. Default value is 1/72 inch (one 'point'), but it has no meaning because personal computers typicaly don't use this value to display/print.
YResolution   double Resolution of image. Default value is 1/72 inch (one 'point'), but it has no meaning because personal computers typicaly don't use this value to display/print.
Software   string Shows firmware(internal software of digicam) version number
DateTime   string Date/Time of image was last modified. Data format is "YYYY:MM:DD HH:MM:SS"+0x00, total 20 bytes. If clock has not set or digicam doesn't have clock, the field may be filled with spaces. Usually it has the same value of DateTimeOriginal.
Copyright   string Shows copyright information.
ExposureTime   double Exposure time (reciprocal of shutter speed). Unit is second.
FNumber   double The actual F-number (F-stop) of lens when the image was taken.
ExposureProgram   integer Exposure program that the camera used when image was taken.
1 means manual control
2 program normal
3 aperture priority
4 shutter priority
5 program creative (slow program)
6 program action (high-speed program)
7 portrait mode
8 landscape mode.
ExifVersion   string Exif version number. Stored as 4 bytes of ASCII characters. If the picture is based on Exif V2.1, value is "0210". Since the type is 'undefined', there is no NULL (0x00) for termination.
DateTimeOriginal   string Date/Time that the original image was taken. This value should not be modified by user program. 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 the Exif standard, this tag is optional, but it is mandatory for DCF.
DateTimeDigitized   string Date/Time of image digitized. Usually, it contains the same value of DateTimeOriginal (0x9003). Data format is "YYYY:MM:DD HH:MM:SS"+0x00, total 20 bytes. If clock has not set or digicam doesn't have clock, the field may be filled with spaces. In the Exif standard, this tag is optional, but it is mandatory for DCF.
CompressedBitsPerPixel   double The average compression ratio of JPEG (rough estimate)
ShutterSpeedValue   double Shutter speed by APEX value. To convert this value to ordinary 'Shutter Speed'; calculate this value's power of 2, then reciprocal. For example, if the ShutterSpeedValue is '4', shutter speed is 1/(24)=1/16 second.
ApertureValue   double The actual aperture value of the lens when the image was taken. Unit is APEX. To convert this value to ordinary F-number (F-stop), calculate this value's power of root 2 (=1.4142). For example, if the ApertureValue is '5', F-number is 1.41425 = F5.6.
BrightnessValue   double Brightness of taken subject, unit is APEX. To calculate Exposure (Ev) from BrigtnessValue (Bv), you must add SensitivityValue(Sv).
Ev=Bv+Sv Sv=log2(ISOSpeedRating/3.125)
ISO100:Sv=5, ISO200:Sv=6, ISO400:Sv=7, ISO125:Sv=5.32.
ExposureBiasValue   double Exposure bias (compensation) value of taking picture. Unit is APEX (EV).
MaxApertureValue   double Maximum aperture value of the lens. Convert to F-number by calculating power of root 2 (same process as ApertureValue).
SubjectDistance   double Distance to focus point, unit is meters.
MeteringMode   integer Exposure metering method:
0 means unknown
1 average
2 center weighted average
3 spot
4 multi-spot
5 multi-segment
6 partial
255 other
LightSource   integer Light source, actually this means white balance setting:
0 means unknown
1 daylight
2 fluorescent
3 tungsten
10 flash
17 standard light A
18 standard light B
19 standard light C
20 D55
21 D65
22 D75
255 other
Flash   integer 0 means flash did not fire
1 flash fired
5 flash fired but strobe return light not detected
7 flash fired and strobe return light detected
FocalLength   double Focal length of lens used to take image. Unit is millimeters.
SubsecTime   string 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"
SubsecTimeOriginal   string 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"
SubsecTimeDigitized   string 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"
FlashPixVersion   string Stores FlashPix version. If the image data is based on FlashPix format Ver.1.0, value is "0100".
ColorSpace   string Defines Color Space. DCF image must use sRGB color space so value is always '1'. If the picture uses the other color space, value is '65535':Uncalibrated.
ExifImageWidth   integer Size of main image.
ExifImageHeight   integer Size of main image.
RelatedSoundFile   string If this digicam can record audio data with image, shows name of audio data.
FocalPlaneXResolution   double Pixel density at CCD's position. If you have MegaPixel digicam and take a picture by lower resolution (e.g.VGA mode), this value is re-sampled by picture resolution. In such case, FocalPlaneResolution is not same as CCD's actual resolution.
FocalPlaneYResolution   double Pixel density at CCD's position. If you have MegaPixel digicam and take a picture by lower resolution (e.g.VGA mode), this value is re-sampled by picture resolution. In such case, FocalPlaneResolution is not same as CCD's actual resolution.
FocalPlaneResolutionUnit   integer Unit of FocalPlaneXResoluton/FocalPlaneYResolution:
1 means no-unit
2 inch
3 centimeter
Note: Some of Fujifilm's digicams (e.g. FX2700, FX2900, Finepix 4700Z/40i, etc.) use value '3' so it must be 'centimeter', but it seems that they use a '8.3mm?' (1/3in.?) to their ResolutionUnit. Fuji's BUG? Finepix4900Z has been changed to use value '2' but it doesn't match to actual value either.
ExposureIndex   double Same as ISOSpeedRatings (0x8827) but data type is unsigned rational. Only Kodak's digicam uses this tag instead of ISOSpeedRating.
SensingMethod   integer Shows type of image sensor unit. '2' means 1 chip color area sensor. Most all digicams use this type.
FileSource   integer Indicates the image source. Value '0x03' means the image source is a digital still camera.
SceneType   integer Indicates the type of scene. Value of '0x01' means that the image was directly photographed.
