| 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 initial version accompanied the launch of DNG and related products. It was a rare, possibly unique, example of a raw image format specification published by its owner. It was adequate for representing typical images, but it had a few errors and deficiencies (specifically the lack of support for "masked pixels" and an inadvertent deviation from the JPEG specification) that required it soon to be replaced by the next version. |
