Description The Digital Negative (DNG) Specification describes a non-proprietary file format for storing camera raw files that can be used by a wide range of hardware and software vendors. DNG is an extension of the TIFF 6.0 format, and is compatible with the TIFF-EP standard. This version, published June 2009, added various improvements, but the major change was to introduce "Opcodes". An Opcode and any associated parameters identifies a specific process to be applied to some or all of the raw image data during the conversion process.
