Gets or sets the exposure bias. The unit is the APEX value. Ordinarily it is given in the range of –99.99 to 99.99.

Gets or sets the exposure index selected on the camera or input device at the time the image was captured.

Gets or sets the exposure mode set when the image was shot. In auto-bracketing mode, the camera shoots a series of frames of the same scene at different exposure settings. See remarks for further information.

Gets or sets the class of the program used by the camera to set exposure when the picture is taken. See remarks for further information.

Gets or the exposure time, given in seconds (sec).

Gets or sets the image source. If a DSC recorded the image, this tag value of this tag always be set to 3, indicating that the image was recorded on a DSC.

Gets or sets a value indicating the status of flash when the image was shot. Bit 0 indicates the flash firing status, bits 1 and 2 indicate the flash return status, bits 3 and 4 indicate the flash mode, bit 5 indicates whether the flash function is present, and bit 6 indicates "red eye" mode.

Gets or sets the strobe energy at the time the image is captured, as measured in Beam Candle Power Seconds (BCPS).

Gets or sets the Flashpix format version supported by a FPXR file. Constant length or 4.

Gets or the F number.

Gets or sets the actual focal length of the lens, in mm. Conversion is not made to the focal length of a 35 mm film camera.

Gets or sets the equivalent focal length assuming a 35mm film camera, in mm. A value of 0 means the focal length is unknown. Note that this tag differs from the FocalLength tag.

Gets or sets the unit for measuring FocalPlaneXResolution and FocalPlaneYResolution. This value is the same as the ResolutionUnit.

Gets or sets the number of pixels in the image width (X) direction per FocalPlaneResolutionUnit on the camera focal plane.

Gets or sets the number of pixels in the image height (Y) direction per FocalPlaneResolutionUnit on the camera focal plane.

Gets or sets the degree of overall image gain adjustment. See remarks for further information.

Gets or sets an identifier assigned uniquely to each image. It is recorded as an ASCII string equivalent to hexadecimal notation and 128-bit fixed length. Constant length of 32.

Gets or sets the the ISO Speed and ISO Latitude of the camera or input device as specified in ISO 12232.

Returns the metadata tag at the given index. This operation is slow when accessing all tags.

Gets or sets the kind of light source. See remarks for further information.

Returns a list of all metadata tags this instance represents.

Gets or sets a tag for manufacturers of Exif writers to record any desired information. The contents are up to the manufacturer, but this tag should not be used for any other than its intended purpose.

Gets or sets the smallest F number of the lens. The unit is the APEX value. Ordinarily it is given in the range of 00.00 to 99.99, but it is not limited to this range.

Gets or sets the metering mode. See remarks for further information.

Retrieves the datamodel that this instance represents.

Gets or sets the Opto-Electric Conversion Function (OECF) specified in ISO 14524. OECF is the relationship between the camera optical input and the image values.

Gets or sets the valid width of a compressed image.

Gets or sets the valid height of a compressed image.

Gets or sets the name of an audio file related to the image data. The format is 8.3. Constant length of 12

Gets or sets the direction of saturation processing applied by the camera when the image was shot. See remarks for further information.

Gets or sets the type of scene that was shot. It can also be used to record the mode in which the image was shot. See remarks for further information.

Gets or sets the type of scene. If a DSC recorded the image, this tag value shall always be set to 1, indicating that the image was directly photographed.

Gets or sets the image sensor type on the camera or input device. See remarks for further information.

Gets or sets the direction of sharpness processing applied by the camera when the image was shot. See remarks for further information.

Gets or sets the shutter speed. The unit is the APEX (Additive System of Photographic Exposure).

Gets or sets the camera or input device spatial frequency table and SFR values in the direction of image width, image height, and diagonal direction, as specified in ISO 12233.

Gets or sets the spectral sensitivity of each channel of the camera used.

Gets or sets a value indicating the location and area of the main subject in the overall scene. Variable length between 2 and 4.

Gets or sets distance to the subject, given in meters. Note that if the numerator of the recorded value is FFFFFFFF, infinity shall be indicated; and if the numerator is 0, distance unknown shall be indicated.

Gets or sets the distance to the subject. See remarks for further information.

Gets or sets the location of the main subject in the scene. The value of this tag represents the pixel at the center of the main subject relative to the left edge, prior to rotation processing as per the Rotation tag. The first value indicates the X column number and second indicates the Y row number.

Gets or sets a tag used to record fractions of seconds for the DateTime tag.

Gets or sets a tag used to record fractions of seconds for the DateTimeDigitized tag.

Gets or sets a tag used to record fractions of seconds for the DateTimeOriginal tag.

Gets or sets a tag for Exif users to write keywords or comments on the image besides those in ImageDescription, and without the character code limitations of the ImageDescription tag. Minimum length of 8. See remarks for further information.

Gets or sets the white balance mode set when the image was shot. See remarks for further information.
