Digital Negative (DNG) is an open, lossless raw image format developed by Adobe and used for digital photography. It was launched on September 27, 2004.[1] The launch was accompanied by the first version of the DNG specification,[2] 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.[3]
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.[4]
