Linear raw when produced by certain cameras or by demosaicing CFA data. Used when the Photometric Interpretation is YCbCr or grayscale. In DNG, this compression is applied to the raw camera data. JPEG Original Lossless Compression (ISO/IEC 10918).
Adobe and others describe the relationship as "extension" Comments welcome. In Notes below, see the comment concerning what is sometimes called Linear DNG as compared to Raw DNG. The DNG specification states, "It is possible (but not required) for a DNG file to simultaneously comply with both the Digital Negative specification and the TIFF/EP standard." (p. Many commentators refer to DNG as an extension of TIFF_6 format and note its compatibility with the TIFF/EP standard. The special metadata is later used in various applications that interpret the camera raw data to produce a variety of image outputs. The conversion applications also generate special metadata about image characteristics that is recorded under DNG tags that represent an extension to the normal TIFF set see Notes below. The "default" action usually produces a version of the still-mosaiced raw data compressed with JPEG_orig_LL.
These applications give users options for processing the raw image data into various versions, as indicated by the "may contain" relationships in this description and discussed in Notes below.

The raw image data is processed for placement in the DNG file wrapper by software applications like Adobe Camera Raw, a plug-in for PhotoShop. Adobe Digital Negative (DNG), Version 1.1įile format for storing and interchanging CAM_RAW (camera raw) images, usually accompanied by JPEG secondary version(s) of the images.
