Add Visible Light Photography Attributes corresponding to EXIF 2.31 and TIFF/EP Status November 2018 Voting Packet Date of Last Update 2018/09/18 Person Assigned David Clunie Submitter Name ICC MIWG Submission Date 2017/07/24 Correction Number CP-1736 Log Summary: Add Visible Light Photography Attributes corresponding to EXIF 2.31 and TIFF/EP Name of Standard PS3.3, PS3.6, PS3.15, PS3.17 Rationale for Correction: The Attributes describing the acquisition of visible light photographic images are currently lacking detail related to the characteristics and identification of the camera and lens and the parameters of the acquisition process such as sensitivity. These have been standardized by consumer and professional grade camera manufacturers and reused in many mobile phone devices in the EXIF standard, the most recent version of which is 2.31, as well as the ISO 12234-2 TIFF/EP standard. This information needs to be made available at the DICOM Attribute level so that they can be accessed and indexed in the normal manner, rather than requiring extraction from the compressed bit stream (e.g., the JPEG APP1 marker segment, which may contain TIFF-encoded EXIF data). The intent is that this mapping support the extraction of embedded EXIF information into DICOM Attributes for accessibility in DICOM-based systems. It is not intended to define a deterministic mapping supporting round trip full fidelity conversion from EXIF to DICOM and back to EXIF again. Tags that affect intended transformations, such as Orientation 274 (112.H), are not mapped, since it is expected, for example that the encoder will transpose the image if necessary into the normal viewable DICOM orientation in which the first encoded row is the top of the displayed image and the first encoded column is the left of the displayed image. The new Modules are added to the VL Photographic Image IOD. Mapping of DNG tags is outside the scope of this CP and will be handled in a Supplement about photographic raw data.

Amend DICOM PS3.17 to add new Annex as follows:

Table XXXX-1 describes a mapping of EXIF Tags as defined in and TIFF/EP Tags as defined in to Visible Light Photography related Attributes. The list of EXIF and associated TIFF tags was derived from the table at updated to remove redundancies and resolve differences between EXIF 2.3 and 2.31. The intent is that this mapping support the extraction of embedded EXIF information into DICOM Attributes for accessibility in DICOM-based systems. It is not intended to define a deterministic mapping supporting round trip full fidelity conversion from EXIF to DICOM and back to EXIF again. When mapping EXIF values to DICOM, some tags map to multiple DICOM Attributes and vice versa, as noted. In general, Ascii types are mapped to UT VR (except that dates and times and timezone offsets are mapped to the appropriate DA, TM, DT or SH VR), Short and Long are mapped to IS VR unless they are used for a list of defined terms, in which case US VR is used, Rational and SRational are mapped to DS (VR) (i.e., each numerator and denominator pair is mapped to a single decimal representation), and Undefined is mapped to OB or UT VR as appropriate. In some special cases, the structure within a single EXIF value is expected to be decoded, e.g., the tabular representation of the OECF and Spatial Frequency Response. An appropriate choice of DICOM Specific Character Set and any corresponding character set mappinencoding conversion is expected; special handling of the decoding of character sets may be necessary for some EXIF tags, such as 37510 UserComment.

-	-	-	0x8298	33432	Image	Copyright	Ascii	Copyright information. In this standard the tag is used to indicate both the photographer and editor copyrights. It is the copyright notice of the person or organization claiming rights to the image. The Interoperability copyright statement including date and rights should be written in this field; e.g., "Copyright, John Smith, 19xx. All rights reserved.". In this standard the field records both the photographer and editor copyrights, with each recorded in a separate part of the statement. When there is a clear distinction between the photographer and editor copyrights, these are to be written in the order of photographer followed by editor copyright, separated by NULL (in this case since the statement also ends with a NULL, there are two NULL codes). When only the photographer copyright is given, it is terminated by one NULL code. When only the editor copyright is given, the photographer copyright part consists of one space followed by a terminating NULL code, then the editor copyright is given. When the field is left blank, it is treated as unknown.

			0xc4a5	50341	Image	Print​ImageMatching	Undefined	Print Image Matching, description needed.
			0xc612	50706	Image	DNGVersion	Byte	This tag encodes the DNG four-tier version number. For files compliant with version 1.1.0.0 of the DNG specification, this tag should contain the bytes: 1, 1, 0, 0.
			0xc613	50707	Image	DNGBackward​Version	Byte	This tag specifies the oldest version of the Digital Negative specification for which a file is compatible. Readers shouldnot attempt to read a file if this tag specifies a version number that is higher than the version number of the specification the reader was based on. In addition to checking the version tags, readers should, for all tags, check the types, counts, and values, to verify it is able to correctly read the file.
			0xc614	50708	Image	Unique​CameraModel	Ascii	Defines a unique, non-localized name for the camera model that created the image in the raw file. This name should include the manufacturer's name to avoid conflicts, and should not be localized, even if the camera name itself is localized for different markets (see Localized​CameraModel). This string may be used by reader software to index into per-model preferences and replacement profiles.
(0008,1090)	Manufacturer's Model Name	General Equipment	0xc615	50709	Image	Localized​CameraModel	Byte	Similar to the Unique​CameraModel field, except the name can be localized for different markets to match the localization of the camera name.
			0xc616	50710	Image	CFAPlane​Color	Byte	Provides a mapping between the values in the CFAPattern tag and the plane numbers in Linear​Raw space. This is a required tag for non-RGB CFA images.
			0xc617	50711	Image	CFALayout	Short	Describes the spatial layout of the CFA.
			0xc618	50712	Image	Linearization​Table	Short	Describes a lookup table that maps stored values into linear values. This tag is typically used to increase compression ratios by storing the raw data in a non-linear, more visually uniform space with fewer total encoding levels. If Samples​PerPixel is not equal to one, this single table applies to all the samples for each pixel.
			0xc619	50713	Image	Black​LevelRepeat​Dim	Short	Specifies repeat pattern size for the Black​Level tag.
			0xc61a	50714	Image	Black​Level	Rational	Specifies the zero light (a.k.a. thermal black or black current) encoding level, as a repeating pattern. The origin of this pattern is the top-left corner of the Active​Area rectangle. The values are stored in row-column-sample scan order.
			0xc61b	50715	Image	Black​LevelDeltaH	SRational	If the zero light encoding level is a function of the image column, Black​LevelDeltaH specifies the difference between the zero light encoding level for each column and the baseline zero light encoding level. If Samples​PerPixel is not equal to one, this single table applies to all the samples for each pixel.
			0xc61c	50716	Image	Black​LevelDeltaV	SRational	If the zero light encoding level is a function of the image row, this tag specifies the difference between the zero light encoding level for each row and the baseline zero light encoding level. If Samples​PerPixel is not equal to one, this single table applies to all the samples for each pixel.
			0xc61d	50717	Image	White​Level	Short	This tag specifies the fully saturated encoding level for the raw sample values. Saturation is caused either by the sensor itself becoming highly non-linear in response, or by the camera's analog to digital converter clipping.
			0xc61e	50718	Image	Default​Scale	Rational	Default​Scale is required for cameras with non-square pixels. It specifies the default scale factors for each direction to convert the image to square pixels. Typically these factors are selected to approximately preserve total pixel count. For CFA images that use CFALayout equal to 2, 3, 4, or 5, such as the Fujifilm SuperCCD, these two values should usually differ by a factor of 2.0.
			0xc61f	50719	Image	Default​CropOrigin	Short	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. Default​CropOrigin specifies the origin of the final image area, in raw image coordinates (i.e., before the Default​Scale has been applied), relative to the top-left corner of the Active​Area rectangle.
			0xc620	50720	Image	Default​CropSize	Short	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. Default​CropSize specifies the size of the final image area, in raw image coordinates (i.e., before the Default​Scale has been applied).
			0xc621	50721	Image	Color​Matrix1	SRational	Color​Matrix1 defines a transformation matrix that converts XYZ values to reference camera native color space values, under the first calibration illuminant. The matrix values are stored in row scan order. The Color​Matrix1 tag is required for all non-monochrome DNG files.
			0xc622	50722	Image	Color​Matrix2	SRational	Color​Matrix2 defines a transformation matrix that converts XYZ values to reference camera native color space values, under the second calibration illuminant. The matrix values are stored in row scan order.
			0xc623	50723	Image	Camera​Calibration1	SRational	Camera​Calibration1 defines a calibration matrix that transforms reference camera native space values to individual camera native space values under the first calibration illuminant. The matrix is stored in row scan order. This matrix is stored separately from the matrix specified by the Color​Matrix1 tag to allow raw converters to swap in replacement color matrices based on Unique​CameraModel tag, while still taking advantage of any per-individual camera calibration performed by the camera manufacturer.
			0xc624	50724	Image	Camera​Calibration2	SRational	Camera​Calibration2 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 Color​Matrix2 tag to allow raw converters to swap in replacement color matrices based on Unique​CameraModel tag, while still taking advantage of any per-individual camera calibration performed by the camera manufacturer.
			0xc625	50725	Image	Reduction​Matrix1	SRational	Reduction​Matrix1 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 Color​Planes is greater than 3. The matrix is stored in row scan order.
			0xc626	50726	Image	Reduction​Matrix2	SRational	Reduction​Matrix2 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 Color​Planes is greater than 3. The matrix is stored in row scan order.
			0xc627	50727	Image	Analog​Balance	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. Analog​Balance defines the gain, either analog (recommended) or digital (not recommended) that has been applied the stored raw values.
			0xc628	50728	Image	As​ShotNeutral	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 As​ShotWhiteXY tag.
			0xc629	50729	Image	As​ShotWhiteXY	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 As​ShotNeutral tag.
			0xc62a	50730	Image	Baseline​Exposure	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. Baseline​Exposure 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	Baseline​Noise	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	Baseline​Sharpness	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	Bayer​GreenSplit	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	Linear​ResponseLimit	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. Linear​ResponseLimit specifies the fraction of the encoding range above which the response may become significantly non-linear.
			0xc62f	50735	Image	Camera​SerialNumber	Ascii	Camera​SerialNumber contains the serial number of the camera or camera body that captured the image.
			0xc630	50736	Image	Lens​Info	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	Chroma​BlurRadius	Rational	Chroma​BlurRadius 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	Anti​AliasStrength	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	Shadow​Scale	SRational	This tag is used by Adobe Camera Raw to control the sensitivity of its 'Shadows' slider.
			0xc634	50740	Image	DNGPrivate​Data	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	Maker​NoteSafety	Short	Maker​NoteSafety lets the DNG reader know whether the EXIF Maker​Note 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 Maker​Note should be aware that any thumbnail image embedded in the Maker​Note may be stale, and may not reflect the current state of the full size image.
			0xc65a	50778	Image	Calibration​Illuminant1	Short	The illuminant used for the first set of color calibration tags (Color​Matrix1, Camera​Calibration1, Reduction​Matrix1). The legal values for this tag are the same as the legal values for the Light​Source EXIF tag.
			0xc65b	50779	Image	Calibration​Illuminant2	Short	The illuminant used for an optional second set of color calibration tags (Color​Matrix2, Camera​Calibration2, Reduction​Matrix2). The legal values for this tag are the same as the legal values for the Calibration​Illuminant1 tag; however, if both are included, neither is allowed to have a value of 0 (unknown).
			0xc65c	50780	Image	Best​QualityScale	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 Default​Scale tag need to be multiplied to achieve the best quality image size.
			0xc65d	50781	Image	Raw​DataUniqueID	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	Original​RawFile​Name	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	Original​RawFile​Data	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	Active​Area	Short	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	Masked​Areas	Short	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	As​ShotICCProfile	Undefined	This tag contains an ICC profile that, in conjunction with the As​ShotPre​ProfileMatrix 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	As​ShotPre​ProfileMatrix	SRational	This tag is used in conjunction with the As​ShotICCProfile 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 As​ShotICCProfile tag. The matrix is stored in the row scan order. If Color​Planes 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 As​ShotICCProfile should have three rather than Color​Planes input components.
			0xc691	50833	Image	CurrentICCProfile	Undefined	This tag is used in conjunction with the Current​PreProfile​Matrix tag. The CurrentICCProfile and Current​PreProfile​Matrix tags have the same purpose and usage as the As​ShotICCProfile and As​ShotPre​ProfileMatrix tag pair, except they are for use by raw file editors rather than camera manufacturers.
			0xc692	50834	Image	Current​PreProfile​Matrix	SRational	This tag is used in conjunction with the CurrentICCProfile tag. The CurrentICCProfile and Current​PreProfile​Matrix tags have the same purpose and usage as the As​ShotICCProfile and As​ShotPre​ProfileMatrix tag pair, except they are for use by raw file editors rather than camera manufacturers.
			0xc6bf	50879	Image	Colorimetric​Reference	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	Camera​CalibrationSignature	Byte	A UTF-8 encoded string associated with the Camera​Calibration1 and Camera​Calibration2 tags. The Camera​Calibration1 and Camera​Calibration2 tags should only be used in the DNG color transform if the string stored in the Camera​CalibrationSignature tag exactly matches the string stored in the Profile​CalibrationSignature tag for the selected camera profile.
			0xc6f4	50932	Image	Profile​CalibrationSignature	Byte	A UTF-8 encoded string associated with the camera profile tags. The Camera​Calibration1 and Camera​Calibration2 tags should only be used in the DNG color transfer if the string stored in the Camera​CalibrationSignature tag exactly matches the string stored in the Profile​CalibrationSignature tag for the selected camera profile.
			0xc6f6	50934	Image	As​ShotProfile​Name	Byte	A UTF-8 encoded string containing the name of the "as shot" camera profile, if any.
			0xc6f7	50935	Image	Noise​ReductionApplied	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	Profile​Name	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	Profile​HueSat​MapDims	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 Profile​HueSat​MapData1 and Profile​HueSat​MapData2 tags. The most common case has Value​Divisions equal to 1, so only hue and saturation are used as inputs to the mapping table.
			0xc6fa	50938	Image	Profile​HueSat​MapData1	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	Profile​HueSat​MapData2	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 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.
			0xc6fc	50940	Image	Profile​ToneCurve	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.
			0xc6fd	50941	Image	Profile​EmbedPolicy	Long	This tag contains information about the usage rules for the associated camera profile.
			0xc6fe	50942	Image	Profile​Copyright	Byte	A UTF-8 encoded string containing the copyright information for the camera profile. This string always should be preserved along with the other camera profile tags.
			0xc714	50964	Image	Forward​Matrix1	SRational	This tag defines a matrix that maps white balanced camera colors to XYZ D50 colors.
			0xc715	50965	Image	Forward​Matrix2	SRational	This tag defines a matrix that maps white balanced camera colors to XYZ D50 colors.

			0xc726	50982	Image	Profile​LookTable​Data	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 Profile​HueSat​MapData1 and Profile​HueSat​MapData2 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.
