Raw file formats are popular in digital photography workflows because they offer greater creative control. However, cameras can use many different raw formats, the specifications for which are not publicly available. This means that not every raw file can be read by a variety of software applications. This addresses the lack of an open standard for raw files created by individual camera models and ensures that photographers easily access their files.

Hundreds of software manufacturers such as Apple and Google have developed support for DNG. And respected camera manufacturers such as Leica, Casio, Ricoh, Samsung, and Pentax have introduced cameras that provide direct DNG support. DNG is supported by the following software versions: Photoshop CS to Photoshop CC, Photoshop Elements 3 to Photoshop Elements 12, and all versions of Lightroom. DNG format helps promote archival confidence, since digital imaging software solutions will be able to open raw files more easily in the future. A single raw processing solution enables a more efficient workflow when handling raw files from multiple camera models and manufacturers. A publicly documented and readily available specification can be easily adopted by camera manufacturers and updated to accommodate technology changes. DNG removes a potential barrier to new camera adoption, since raw files from new models will be immediately supported by Photoshop and other applications.

D savings by reducing the need to develop new formats and by simplifying camera testing. A common format allows greater control over the quality of conversions by third-party applications. The specification allows the addition of private metadata to DNG files, enabling differentiation. The Profiles SDK provides resources for creating enhanced profiles introduced in Lightroom Classic CC 7. Download the specification, which describes a nonproprietary file format for storing camera raw files that can be used by a wide range of hardware and software vendors. The DNG SDK provides support for reading and writing DNG files as well as for converting DNG data to a format that is easily displayed or processed by imaging applications.
