Adobe releases DNG 1.2
Adobe has released an update to the Adobe Digital Negative specification (DNG), its publicly available archival format for the raw files generated by digital cameras. The DNG 1.2.0 Specification (May 2008) provides new and expanded specifications that offer increased flexibility and improved workflow for their raw images, including formalization of the concept of a "camera profile" and allowance for multiple camera profiles to be embedded in a single DNG file. Adobe has also defined additional metadata tags for the DNG format, including a field to indicate the integrity of the raw data within the file, offering a tool to validate the safety of photographers' image data. Adobe's DNG SDK has also been updated to reflect the changes to the specification. In addition, a DNG Codec for Windows Vista -- only available for 32-bit editions -- has also been released on Adobe Labs. Adobe DNG Converter is available as a free download from Adobe's website.
