Digital Negative (DNG) is an open source, lossless, well defined camera RAW data container with the goal to replace a range of proprietary, closed source raw image containers. It has been developed by Adobe and was launched on September 27, 2004. The launch was accompanied by the first version of the DNG specification, plus various products, including a free-of-charge DNG converter utility. All Adobe photo manipulation software (such as Adobe Photoshop and Adobe Lightroom) released since the launch supports DNG.
DNG is based on the TIFF/EP standard format, and mandates significant use of metadata. The specification of the file format is open and not subject to any intellectual property restrictions or patents.
