.DNG File

The dng file extension is associated with the universal Digital Negative RAW file format developed by Adobe.

It is non-proprietary and public defined format for camera RAW files that can be used by hardware and software developers for a more flexible RAW processing and archiving workflow. End users can use Digital Negative (DNG) as an intermediate format for storing digital images.

• Archival - DNG files will be readable by software in the distant future.
   
• TIFF compatible - Digital Negative format is an extension of TIFF 6.0 picture image format (compatible with TIFF-EP standard).
