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.
