Photometric Interpretation Attribute

TypeRequired (1)
Value Multiplicity1
Value RepresentationCode String (CS)
Example Values
  • RGB

Specifies the intended interpretation of the pixel data.

See Section C. for Enumerated Values.

Section C.

C. Photometric Interpretation and Samples Per Pixel

See Section C.

Enumerated Values for Photometric Interpretation (0028,0004):






The value shall be appropriate to the compression Transfer Syntax used, if any, and shall be MONOCHROME2 or RGB for uncompressed or lossless compressed Transfer Syntaxes that do not have defined color space transformations, YBR_ICT or RGB for irreversible JPEG 2000 Transfer Syntaxes, YBR_RCT or RGB for reversible JPEG 2000 Transfer Syntaxes, and YBR_FULL_422 or RGB for JPEG lossy compressed Transfer Syntaxes.


  1. Future lossless and lossy Transfer Syntaxes may lead to the need for new definitions and choices for Photometric Interpretation. The Enumerated Values may therefore be extended with additional Photometric Interpretation values directly associated with new Transfer Syntaxes that are negotiated, and hence do not render existing implementations non-conformant.

  2. Motion compression Transfer Syntaxes are not expected to be used for Whole Slide Imaging, so the use of YBR_PARTIAL_420 for MPEG2, MPEG-4 AVC/H.264 and HEVC/H.265 Transfer Syntaxes is not permitted.

  3. The use of RGB with JPEG and JPEG 2000 is only intended to allow for conversion to DICOM of images from proprietary formats for which no color transformation from RGB to YBR was performed and the encoded components really are RGB. The value of Photometric Interpretation (0028,0004) describes what is actually encoded, so a value of RGB is not used when the compressed components are actually YBR.

Multi-spectral images may be encoded as a single wavelength band (color) in each frame using MONOCHROME2, or with up to three bands in each frame using one of the color Photometric Interpretations.

Enumerated Values for Samples per Pixel (0028,0002) when Photometric Interpretation (0028,0004) is MONOCHROME2:
