Raw file formats are extremely popular in digital photography workflows because they offer creative professionals greater creative control. However, cameras can use many different raw formats — the specifications for which are not publicly available — which 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 even more challenging.
The solution to this is Digital Negative (DNG), a publicly available archival format for the raw files generated by digital cameras. By addressing the lack of an open standard for the raw files created by individual camera models, DNG helps ensure that photographers will be able to access their files in the future.
The camera raw converter functionality in Adobe Photoshop software provides fast and easy access to the raw image formats produced by many leading professional and midrange digital cameras. By working with these “digital negatives,” you can achieve the results you want with greater artistic control and flexibility while still maintaining the original raw files.
The Adobe DNG Converter, a free utility that converts files from more than 150 cameras to DNG, enables you to easily convert camera-specific raw files to a more universal DNG raw file.
Digital Negative was developed to address the lack of an open standard for the proprietary and unique raw files created by each digital camera. DNG allows photographers to archive their raw camera files in a single format for easy cataloging and access in the future. With the format specification freely available, any developer can build software that supports and takes advantage of DNG.
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.
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. 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.
