0xc61f 50719 Image Exif.Image.DefaultCropOrigin Long Raw images often store extra pixels around the edges of the final image. These extra pixels help prevent interpolation artifacts near the edges of the final image. DefaultCropOrigin specifies the origin of the final image area, in raw image coordinates (i.e., before the DefaultScale has been applied), relative to the top-left corner of the ActiveArea rectangle.
0xc620 50720 Image Exif.Image.DefaultCropSize Long Raw images often store extra pixels around the edges of the final image. These extra pixels help prevent interpolation artifacts near the edges of the final image.

The matrix is stored in row scan order. This matrix is stored separately from the matrix specified by the ColorMatrix1 tag to allow raw converters to swap in replacement color matrices based on UniqueCameraModel tag, while still taking advantage of any per-individual camera calibration performed by the camera manufacturer.
0xc624 50724 Image Exif.Image.CameraCalibration2 SRational CameraCalibration2 defines a calibration matrix that transforms reference camera native space values to individual camera native space values under the second calibration illuminant. The matrix is stored in row scan order. This matrix is stored separately from the matrix specified by the ColorMatrix2 tag to allow raw converters to swap in replacement color matrices based on UniqueCameraModel tag, while still taking advantage of any per-individual camera calibration performed by the camera manufacturer.
0xc625 50725 Image Exif.Image.ReductionMatrix1 SRational ReductionMatrix1 defines a dimensionality reduction matrix for use as the first stage in converting color camera native space values to XYZ values, under the first calibration illuminant. This tag may only be used if ColorPlanes is greater than 3. The matrix is stored in row scan order.
0xc626 50726 Image Exif.Image.ReductionMatrix2 SRational ReductionMatrix2 defines a dimensionality reduction matrix for use as the first stage in converting color camera native space values to XYZ values, under the second calibration illuminant. This tag may only be used if ColorPlanes is greater than 3. The matrix is stored in row scan order.
0xc627 50727 Image Exif.Image.AnalogBalance Rational Normally the stored raw values are not white balanced, since any digital white balancing will reduce the dynamic range of the final image if the user decides to later adjust the white balance; however, if camera hardware is capable of white balancing the color channels before the signal is digitized, it can improve the dynamic range of the final image. AnalogBalance defines the gain, either analog (recommended) or digital (not recommended) that has been applied the stored raw values.
0xc628 50728 Image Exif.Image.AsShotNeutral Short Specifies the selected white balance at time of capture, encoded as the coordinates of a perfectly neutral color in linear reference space values. The inclusion of this tag precludes the inclusion of the AsShotWhiteXY tag.
0xc629 50729 Image Exif.Image.AsShotWhiteXY Rational Specifies the selected white balance at time of capture, encoded as x-y chromaticity coordinates. The inclusion of this tag precludes the inclusion of the AsShotNeutral tag.
0xc62a 50730 Image Exif.Image.BaselineExposure SRational Camera models vary in the trade-off they make between highlight headroom and shadow noise. Some leave a significant amount of highlight headroom during a normal exposure. This allows significant negative exposure compensation to be applied during raw conversion, but also means normal exposures will contain more shadow noise. Other models leave less headroom during normal exposures. This allows for less negative exposure compensation, but results in lower shadow noise for normal exposures. Because of these differences, a raw converter needs to vary the zero point of its exposure compensation control from model to model. BaselineExposure specifies by how much (in EV units) to move the zero point. Positive values result in brighter default results, while negative values result in darker default results.
0xc62b 50731 Image Exif.Image.BaselineNoise Rational Specifies the relative noise level of the camera model at a baseline ISO value of 100, compared to a reference camera model. Since noise levels tend to vary approximately with the square root of the ISO value, a raw converter can use this value, combined with the current ISO, to estimate the relative noise level of the current image.
0xc62c 50732 Image Exif.Image.BaselineSharpness Rational Specifies the relative amount of sharpening required for this camera model, compared to a reference camera model. Camera models vary in the strengths of their anti-aliasing filters. Cameras with weak or no filters require less sharpening than cameras with strong anti-aliasing filters.
0xc62d 50733 Image Exif.Image.BayerGreenSplit Long Only applies to CFA images using a Bayer pattern filter array. This tag specifies, in arbitrary units, how closely the values of the green pixels in the blue/green rows track the values of the green pixels in the red/green rows. A value of zero means the two kinds of green pixels track closely, while a non-zero value means they sometimes diverge. The useful range for this tag is from 0 (no divergence) to about 5000 (quite large divergence).
0xc62e 50734 Image Exif.Image.LinearResponseLimit Rational Some sensors have an unpredictable non-linearity in their response as they near the upper limit of their encoding range. This non-linearity results in color shifts in the highlight areas of the resulting image unless the raw converter compensates for this effect. LinearResponseLimit specifies the fraction of the encoding range above which the response may become significantly non-linear.
0xc62f 50735 Image Exif.Image.CameraSerialNumber Ascii CameraSerialNumber contains the serial number of the camera or camera body that captured the image.
0xc630 50736 Image Exif.Image.LensInfo Rational Contains information about the lens that captured the image. If the minimum f-stops are unknown, they should be encoded as 0/0.
0xc631 50737 Image Exif.Image.ChromaBlurRadius Rational ChromaBlurRadius provides a hint to the DNG reader about how much chroma blur should be applied to the image. If this tag is omitted, the reader will use its default amount of chroma blurring. Normally this tag is only included for non-CFA images, since the amount of chroma blur required for mosaic images is highly dependent on the de-mosaic algorithm, in which case the DNG reader's default value is likely optimized for its particular de-mosaic algorithm.
0xc632 50738 Image Exif.Image.AntiAliasStrength Rational Provides a hint to the DNG reader about how strong the camera's anti-alias filter is. A value of 0.0 means no anti-alias filter (i.e., the camera is prone to aliasing artifacts with some subjects), while a value of 1.0 means a strong anti-alias filter (i.e., the camera almost never has aliasing artifacts).
0xc633 50739 Image Exif.Image.ShadowScale SRational This tag is used by Adobe Camera Raw to control the sensitivity of its 'Shadows' slider.
0xc634 50740 Image Exif.Image.DNGPrivateData Byte Provides a way for camera manufacturers to store private data in the DNG file for use by their own raw converters, and to have that data preserved by programs that edit DNG files.
0xc635 50741 Image Exif.Image.MakerNoteSafety Short MakerNoteSafety lets the DNG reader know whether the EXIF MakerNote tag is safe to preserve along with the rest of the EXIF data. File browsers and other image management software processing an image with a preserved MakerNote should be aware that any thumbnail image embedded in the MakerNote may be stale, and may not reflect the current state of the full size image.
0xc65a 50778 Image Exif.Image.CalibrationIlluminant1 Short The illuminant used for the first set of color calibration tags (ColorMatrix1, CameraCalibration1, ReductionMatrix1). The legal values for this tag are the same as the legal values for the LightSource EXIF tag. If set to 255 (Other), then the IFD must also include a IlluminantData1 tag to specify the x-y chromaticity or spectral power distribution function for this illuminant.
0xc65b 50779 Image Exif.Image.CalibrationIlluminant2 Short The illuminant used for an optional second set of color calibration tags (ColorMatrix2, CameraCalibration2, ReductionMatrix2). The legal values for this tag are the same as the legal values for the CalibrationIlluminant1 tag; however, if both are included, neither is allowed to have a value of 0 (unknown). If set to 255 (Other), then the IFD must also include a IlluminantData2 tag to specify the x-y chromaticity or spectral power distribution function for this illuminant.
0xc65c 50780 Image Exif.Image.BestQualityScale Rational For some cameras, the best possible image quality is not achieved by preserving the total pixel count during conversion. For example, Fujifilm SuperCCD images have maximum detail when their total pixel count is doubled. This tag specifies the amount by which the values of the DefaultScale tag need to be multiplied to achieve the best quality image size.
0xc65d 50781 Image Exif.Image.RawDataUniqueID Byte This tag contains a 16-byte unique identifier for the raw image data in the DNG file. DNG readers can use this tag to recognize a particular raw image, even if the file's name or the metadata contained in the file has been changed. If a DNG writer creates such an identifier, it should do so using an algorithm that will ensure that it is very unlikely two different images will end up having the same identifier.
0xc68b 50827 Image Exif.Image.OriginalRawFileName Byte If the DNG file was converted from a non-DNG raw file, then this tag contains the file name of that original raw file.
0xc68c 50828 Image Exif.Image.OriginalRawFileData Undefined If the DNG file was converted from a non-DNG raw file, then this tag contains the compressed contents of that original raw file. The contents of this tag always use the big-endian byte order. The tag contains a sequence of data blocks. Future versions of the DNG specification may define additional data blocks, so DNG readers should ignore extra bytes when parsing this tag. DNG readers should also detect the case where data blocks are missing from the end of the sequence, and should assume a default value for all the missing blocks. There are no padding or alignment bytes between data blocks.
0xc68d 50829 Image Exif.Image.ActiveArea Long This rectangle defines the active (non-masked) pixels of the sensor. The order of the rectangle coordinates is: top, left, bottom, right.
0xc68e 50830 Image Exif.Image.MaskedAreas Long This tag contains a list of non-overlapping rectangle coordinates of fully masked pixels, which can be optionally used by DNG readers to measure the black encoding level. The order of each rectangle's coordinates is: top, left, bottom, right. If the raw image data has already had its black encoding level subtracted, then this tag should not be used, since the masked pixels are no longer useful.
0xc68f 50831 Image Exif.Image.AsShotICCProfile Undefined This tag contains an ICC profile that, in conjunction with the AsShotPreProfileMatrix tag, provides the camera manufacturer with a way to specify a default color rendering from camera color space coordinates (linear reference values) into the ICC profile connection space. The ICC profile connection space is an output referred colorimetric space, whereas the other color calibration tags in DNG specify a conversion into a scene referred colorimetric space. This means that the rendering in this profile should include any desired tone and gamut mapping needed to convert between scene referred values and output referred values.
0xc690 50832 Image Exif.Image.AsShotPreProfileMatrix SRational This tag is used in conjunction with the AsShotICCProfile tag. It specifies a matrix that should be applied to the camera color space coordinates before processing the values through the ICC profile specified in the AsShotICCProfile tag. The matrix is stored in the row scan order. If ColorPlanes is greater than three, then this matrix can (but is not required to) reduce the dimensionality of the color data down to three components, in which case the AsShotICCProfile should have three rather than ColorPlanes input components.
0xc691 50833 Image Exif.Image.CurrentICCProfile Undefined This tag is used in conjunction with the CurrentPreProfileMatrix tag. The CurrentICCProfile and CurrentPreProfileMatrix tags have the same purpose and usage as the AsShotICCProfile and AsShotPreProfileMatrix tag pair, except they are for use by raw file editors rather than camera manufacturers.
0xc692 50834 Image Exif.Image.CurrentPreProfileMatrix SRational This tag is used in conjunction with the CurrentICCProfile tag. The CurrentICCProfile and CurrentPreProfileMatrix tags have the same purpose and usage as the AsShotICCProfile and AsShotPreProfileMatrix tag pair, except they are for use by raw file editors rather than camera manufacturers.
0xc6bf 50879 Image Exif.Image.ColorimetricReference Short The DNG color model documents a transform between camera colors and CIE XYZ values. This tag describes the colorimetric reference for the CIE XYZ values. 0 = The XYZ values are scene-referred. 1 = The XYZ values are output-referred, using the ICC profile perceptual dynamic range. This tag allows output-referred data to be stored in DNG files and still processed correctly by DNG readers.
0xc6f3 50931 Image Exif.Image.CameraCalibrationSignature Byte A UTF-8 encoded string associated with the CameraCalibration1 and CameraCalibration2 tags. The CameraCalibration1 and CameraCalibration2 tags should only be used in the DNG color transform if the string stored in the CameraCalibrationSignature tag exactly matches the string stored in the ProfileCalibrationSignature tag for the selected camera profile.
0xc6f4 50932 Image Exif.Image.ProfileCalibrationSignature Byte A UTF-8 encoded string associated with the camera profile tags. The CameraCalibration1 and CameraCalibration2 tags should only be used in the DNG color transfer if the string stored in the CameraCalibrationSignature tag exactly matches the string stored in the ProfileCalibrationSignature tag for the selected camera profile.
0xc6f5 50933 Image Exif.Image.ExtraCameraProfiles Long A list of file offsets to extra Camera Profile IFDs. Note that the primary camera profile tags should be stored in IFD 0, and the ExtraCameraProfiles tag should only be used if there is more than one camera profile stored in the DNG file.
0xc6f6 50934 Image Exif.Image.AsShotProfileName Byte A UTF-8 encoded string containing the name of the "as shot" camera profile, if any.
0xc6f7 50935 Image Exif.Image.NoiseReductionApplied Rational This tag indicates how much noise reduction has been applied to the raw data on a scale of 0.0 to 1.0. A 0.0 value indicates that no noise reduction has been applied. A 1.0 value indicates that the "ideal" amount of noise reduction has been applied, i.e. that the DNG reader should not apply additional noise reduction by default. A value of 0/0 indicates that this parameter is unknown.
0xc6f8 50936 Image Exif.Image.ProfileName Byte A UTF-8 encoded string containing the name of the camera profile. This tag is optional if there is only a single camera profile stored in the file but is required for all camera profiles if there is more than one camera profile stored in the file.
0xc6f9 50937 Image Exif.Image.ProfileHueSatMapDims Long This tag specifies the number of input samples in each dimension of the hue/saturation/value mapping tables. The data for these tables are stored in ProfileHueSatMapData1, ProfileHueSatMapData2 and ProfileHueSatMapData3 tags. The most common case has ValueDivisions equal to 1, so only hue and saturation are used as inputs to the mapping table.
0xc6fa 50938 Image Exif.Image.ProfileHueSatMapData1 Float This tag contains the data for the first hue/saturation/value mapping table. Each entry of the table contains three 32-bit IEEE floating-point values. The first entry is hue shift in degrees; the second entry is saturation scale factor; and the third entry is a value scale factor. The table entries are stored in the tag in nested loop order, with the value divisions in the outer loop, the hue divisions in the middle loop, and the saturation divisions in the inner loop. All zero input saturation entries are required to have a value scale factor of 1.0.
0xc6fb 50939 Image Exif.Image.ProfileHueSatMapData2 Float This tag contains the data for the second hue/saturation/value mapping table. Each entry of the table contains three 32-bit IEEE floating-point values.

The table entries are stored in the tag in nested loop order, with the value divisions in the outer loop, the hue divisions in the middle loop, and the saturation divisions in the inner loop. All zero input saturation entries are required to have a value scale factor of 1.0.
0xc6fc 50940 Image Exif.Image.ProfileToneCurve Float This tag contains a default tone curve that can be applied while processing the image as a starting point for user adjustments. The curve is specified as a list of 32-bit IEEE floating-point value pairs in linear gamma. Each sample has an input value in the range of 0.0 to 1.0, and an output value in the range of 0.0 to 1.0. The first sample is required to be (0.0, 0.0), and the last sample is required to be (1.0, 1.0). Interpolated the curve using a cubic spline.

0xc71a 50970 Image Exif.Image.PreviewColorSpace Long This tag specifies the color space in which the rendered preview in this IFD is stored. The default value for this tag is sRGB for color previews and Gray Gamma 2.2 for monochrome previews.
0xc71b 50971 Image Exif.Image.PreviewDateTime Ascii This tag is an ASCII string containing the name of the date/time at which the preview stored in the IFD was rendered. The date/time is encoded using ISO 8601 format.
0xc71c 50972 Image Exif.Image.RawImageDigest Undefined This tag is an MD5 digest of the raw image data. All pixels in the image are processed in row-scan order. Each pixel is zero padded to 16 or 32 bits deep (16-bit for data less than or equal to 16 bits deep, 32-bit otherwise). The data for each pixel is processed in little-endian byte order.
0xc71d 50973 Image Exif.Image.OriginalRawFileDigest Undefined This tag is an MD5 digest of the data stored in the OriginalRawFileData tag.
0xc71e 50974 Image Exif.Image.SubTileBlockSize Long Normally, the pixels within a tile are stored in simple row-scan order. This tag specifies that the pixels within a tile should be grouped first into rectangular blocks of the specified size. These blocks are stored in row-scan order. Within each block, the pixels are stored in row-scan order. The use of a non-default value for this tag requires setting the DNGBackwardVersion tag to at least 1.2.0.0.

0xc726 50982 Image Exif.Image.ProfileLookTableData Float This tag contains a default "look" table that can be applied while processing the image as a starting point for user adjustment. This table uses the same format as the tables stored in the ProfileHueSatMapData1 and ProfileHueSatMapData2 tags, and is applied in the same color space. However, it should be applied later in the processing pipe, after any exposure compensation and/or fill light stages, but before any tone curve stage. Each entry of the table contains three 32-bit IEEE floating-point values. The first entry is hue shift in degrees, the second entry is a saturation scale factor, and the third entry is a value scale factor. The table entries are stored in the tag in nested loop order, with the value divisions in the outer loop, the hue divisions in the middle loop, and the saturation divisions in the inner loop. All zero input saturation entries are required to have a value scale factor of 1.0.

0xc74e 51022 Image Exif.Image.OpcodeList3 Undefined Specifies the list of opcodes that should be applied to the raw image, just after it has been demosaiced.
0xc761 51041 Image Exif.Image.NoiseProfile Double NoiseProfile describes the amount of noise in a raw image. Specifically, this tag models the amount of signal-dependent photon (shot) noise and signal-independent sensor readout noise, two common sources of noise in raw images. The model assumes that the noise is white and spatially independent, ignoring fixed pattern effects and other sources of noise (e.g., pixel response non-uniformity, spatially-dependent thermal effects, etc.).
0xc763 51043 Image Exif.Image.TimeCodes Byte The optional TimeCodes tag shall contain an ordered array of time codes. All time codes shall be 8 bytes long and in binary format. The tag may contain from 1 to 10 time codes. When the tag contains more than one time code, the first one shall be the default time code. This specification does not prescribe how to use multiple time codes. Each time code shall be as defined for the 8-byte time code structure in SMPTE 331M-2004, Section 8.3. See also SMPTE 12-1-2008 and SMPTE 309-1999.

The default value for this tag is default final size of the current DNG file, which is DefaultCropSize * DefaultScale.
0xc792 51090 Image Exif.Image.OriginalBestQualityFinalSize Long If this file is a proxy for a larger original DNG file, this tag specifics the best quality final size of the larger original file from which this proxy was generated. The default value for this tag is the OriginalDefaultFinalSize, if specified.

0xc7a5 51109 Image Exif.Image.BaselineExposureOffset SRational Provides a way for color profiles to increase or decrease exposure during raw conversion. BaselineExposureOffset specifies the amount (in EV units) to add to the BaselineExposure tag during image rendering. For example, if the BaselineExposure value for a given camera model is +0.3, and the BaselineExposureOffset value for a given camera profile used to render an image for that camera model is -0.7, then the actual default exposure value used during rendering will be +0.3 - 0.7 = -0.4.
0xc7a6 51110 Image Exif.Image.DefaultBlackRender Long This optional tag in a color profile provides a hint to the raw converter regarding how to handle the black point (e.g., flare subtraction) during rendering. If set to Auto, the raw converter should perform black subtraction during rendering. If set to None, the raw converter should not perform any black subtraction during rendering.

0xc7e9 51177 Image Exif.Image.DepthFormat Short Specifies the encoding of any depth data in the file. Can be unknown (apart from nearer distances being closer to zero, and farther distances being closer to the maximum value), linear (values vary linearly from zero representing DepthNear to the maximum value representing DepthFar), or inverse (values are stored inverse linearly, with zero representing DepthNear and the maximum value representing DepthFar).
0xc7ea 51178 Image Exif.Image.DepthNear Rational Specifies distance from the camera represented by the zero value in the depth map. 0/0 means unknown.
0xc7eb 51179 Image Exif.Image.DepthFar Rational Specifies distance from the camera represented by the maximum value in the depth map. 0/0 means unknown. 1/0 means infinity, which is valid for unknown and inverse depth formats.

The legal values for this tag are the same as the legal values for the LightSource EXIF tag; CalibrationIlluminant1 and CalibrationIlluminant2 must also be present. If set to 255 (Other), then the IFD must also include a IlluminantData3 tag to specify the x-y chromaticity or spectral power distribution function for this illuminant.
0xcd32 52530 Image Exif.Image.CameraCalibration3 SRational CameraCalibration3 defines a calibration matrix that transforms reference camera native space values to individual camera native space values under the third calibration illuminant. The matrix is stored in row scan order. This matrix is stored separately from the matrix specified by the ColorMatrix3 tag to allow raw converters to swap in replacement color matrices based on UniqueCameraModel tag, while still taking advantage of any per-individual camera calibration performed by the camera manufacturer.
0xcd33 52531 Image Exif.Image.ColorMatrix3 SRational ColorMatrix3 defines a transformation matrix that converts XYZ values to reference camera native color space values, under the third calibration illuminant. The matrix values are stored in row scan order.
