In digital photography, the Digital Negative (DNG) file format is a royalty free RAW image format designed by Adobe Systems. Its specification was announced on September 27, 2004. The same day, Adobe introduced Digital Negative to the market with its free Adobe DNG Converter program. According to Adobe, Digital Negative was a response to demand for a unifying camera raw file format. Digital Negative is based on the TIFF/EP format, and mandates use of metadata. All Adobe photo manipulation software (such as Adobe Photoshop and Adobe Lightroom) released since the announcement supports DNG.
