The Common sub-tree contains values that are common or useful for all raw files.
All values in the Common sub-tree have Type = VALUE_ITEM and are Read Only.
| Name | Id | Description |
|---|---|---|
| AsShotNeutral | IGMDTAG_ID_DCRAW_ASSHOTNEUTRAL | Specifies the selected white balance at time of capture, encoded as the coordinates of a perfectly neutral color in linear reference space values. |
| BaselineExposure | IGMDTAG_ID_DCRAW_BASELINEEXPOSURE | Specifies baseline exposure of the camera, in EV units. Application may use this value to adjust exposure compensation for particular camera model. |
| BitsPerSample | IGMDTAG_ID_DCRAW_BITSPERSAMPLE | Bits per sample in the original raw image (before reconstruction) |
| BlackLevelRepeatDim | IGMDTAG_ID_DCRAW_BLACKLEVELREPEATDIM | This tag specifies repeat pattern size for the "BlackLevel" tag. |
| CalibrationIlluminant1 | IGMDTAG_ID_DCRAW_CALIBRATIONILLUMINANT1 | The illuminant used for ColorMatrix1 color conversion matrix. Allowed values are the same as allowed values for LightSource EXIF tag (see Exif specification). |
| CalibrationIlluminant2 | IGMDTAG_ID_DCRAW_CALIBRATIONILLUMINANT1 | The illuminant used for ColorMatrix2 color conversion matrix. Allowed values are the same as allowed values for LightSource EXIF tag (see Exif specification). |
| CFAPattern | IGMDTAG_ID_DCRAW_CFAPATTERN | This tag encodes the actual color filter array geometric pattern of the image sensor used to capture the single sensor color image. |
| CFARepeatPatternDim | IGMDTAG_ID_DCRAW_CFAREPEATPATTERNDIM | This tag encodes the number of pixels horizontally and vertically that are needed to uniquely define the repeat pattern of the color filter array. |
| ColorMatrix1 | IGMDTAG_ID_DCRAW_COLORMATRIX1 | Conversion matrix from XYZ to camera color space, for illuminant specified by CalibrationIlluminant1 tag. Matrix is stored in row scan order. |
| ColorMatrix2 | IGMDTAG_ID_DCRAW_COLORMATRIX2 | Conversion matrix from XYZ to camera color space, for illuminant specified by CalibrationIlluminant2 tag. Matrix is stored in row scan order. |
| ColorPlanes | IGMDTAG_ID_DCRAW_COLORPLANES | Number of colors in the CFA pattern |
| ImageHeight | IGMDTAG_ID_DCRAW_IMAGEHEIGHT | Image height after that masked pixels were trimmed out |
| ImageWidth | IGMDTAG_ID_DCRAW_IMAGEWIDTH | Image width after that masked pixels were trimmed out |
| Make | IGMDTAG_ID_DCRAW_MAKE | Name of the camera manufacturer |
| Model | IGMDTAG_ID_DCRAW_MODEL | Name of the camera model |
| PhotometricInterpretation | IGMDTAG_ID_DCRAW_PHOTOMETRICINTERPRETATION | TIF_PHOTO_CFA, TIF_PHOTO_RGB |
| RawHeight | IGMDTAG_ID_DCRAW_RAWHEIGHT | Raw Image Height, including masked pixels |
| RawLeft | IGMDTAG_ID_DCRAW_RAWLEFT | X coordinate of first column of non-masked pixels |
| RawTop | IGMDTAG_ID_DCRAW_RAWTOP | Y coordinate of first row of non-masked pixels |
| RawWidth | IGMDTAG_ID_DCRAW_RAWWIDTH | Raw Image Width, including masked pixels |
| SamplesPerPixel | IGMDTAG_ID_DCRAW_SAMPLESPERPIXEL | Number of samples per pixel in the original image, before reconstruction |
| TimeStamp | IGMDTAG_ID_DCRAW_TIMESTAMP | Time stamp |
| UniqueCameraModel | IGMDTAG_ID_DCRAW_UNIQUECAMERAMODEL | Unique, non-localized name for the camera model that created the image in the raw file. |
| WhiteLevel | IGMDTAG_ID_DCRAW_WHITELEVEL | Image pixel value that corresponds to fully saturated encoding level. |
