Article Summary:

Adobe has announced an update in its Digital Negative (DNG) format. The aim of the DNG format is to provide a single archival format that will be supported over time, rather than a specific manufacturer raw format that my cease to supported at some point in the future. It has extended the specifications of the DNG format, and created a more compact, Lossy DNG option, which gives a file size option between that of a full-size DNG and a JPEG. The format has also been extended to keep any in-camera cropping that has been applied to a RAW file, to allow for the inclusion of full HDR data and to retain any non-image areas around merged panoramas.

The full specification is available as a pdf download and there is also an updated free DNG converter available.
