Last updated:. November 20, User rating:. A single raw processing solution enables a more efficient workflow when handling raw files from multiple camera models and manufacturers. Unlike most manufacturer-specific raw formats, the Digital Negative is an openly published specification that not only is supported by Adobe, but is also freely available for other software and hardware vendors to support. Consequently, it can be a safer file format to use for long-term archival purposes.
Archiving your file as a digital negative eliminates worries that the raw file will no longer be readable once the camera format that created it becomes obsolete. The Digital Negative specification allows for not only all of the pixel information stored in current raw formats, but also for all of the additional, proprietary metadata that many manufacturers include.
The Adobe DNG Converter may, in some cases, ignore some of this proprietary metadata, and only include the basic information necessary for creating a high-quality image file. The original raw file, however, can also be embedded in the new DNG format to ensure that proprietary metadata from the manufacturer is not lost. Legal Notices Online Privacy Policy.
