The public archival format for digital camera raw data
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. As a result, the use of these proprietary raw files as a long-term archival solution carries risk and sharing these files across complex workflows is challenging.
Digital Negative (DNG) is a publicly available archival format for raw files which are generated by various digital cameras. This addresses the lack of an open standard for raw files created by individual camera models and ensures that photographers easily access their files.
Adobe Photoshop now works across desktop and iPad, so you can do everyday edits or total image transformations wherever inspiration strikes. Crop, remove objects, retouch, and combine photos. Play with color and effects. Photoshop on the iPad is included with your Creative Cloud Photography plan. Learn more about Photoshop on the iPad. Adobe Photoshop Lightoom, sometimes shortened to Adobe Lightroom, is a post-production photo editing and viewing program from Adobe. Mark Hamburg was a senior engineer on the Adobe Photoshop team who eventually became the software architect. However, Hamburg left the team after Photoshop 7 shipped in April 2002. He resumed work on a project which he started in 1999 with a different.
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. To learn more, see Camera Raw.
In addition to the Digital Negative Specification, Adobe provides the free Adobe DNG Converter (Windows | Mac OS), which easily translates raw files from many of today's popular cameras. Software developers and manufacturers can download the complete DNG Specification (PDF, 742 KB). DNG is supported by the following software versions: Photoshop CS to Photoshop, Photoshop Elements 3 to Photoshop Elements 12, and all versions of Lightroom.
For photographers:
- 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.
For hardware and software manufacturers:
- DNG removes a potential barrier to new camera adoption, since raw files from new models will be immediately supported by Photoshop and other applications.
- The DNG format allows R&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 7.3, Lightroom CC 1.3, and Camera Raw 10.3.
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. This SDK can serve as a starting point for the addition of DNG support to existing applications that use and manipulate images or as an aid to the inclusion of DNG support within cameras.
