The .dng filename extension stands for the Adobe Digital Negative (DNG) file format and the associated DNG Image (.dng) file type. Created by Adobe Systems and released under an open specification, DNG is advocated as an open alternative to proprietary RAW formats. Whether DNG should be preferred to vendor-locked RAW formats is still a matter of much debate in professional photography.
A .dng file is a raw, unprocessed Digital Negative image. Like other RAW image files, it stores data obtained from a camera's sensor with extensive metadata and requires developing. Inside a .dng file, image data are stored compressed, yet without quality loss, taking up less disk space than most vendor-specific RAW formats. DNG embeds image metadata into the file itself and allows destructive editing.
Besides the DNG support offered by major graphics editors, there are hosts of various online and offline DNG converters, optimizers, and other DNG-related tools. Additionally, Adobe provides their free Adobe DNG Codec that allows to directly browse and view .dng images in Microsoft Windows 7 and later.
