Adobe today introduced the Digital Negative Specification (.DNG), a new unified public format for raw digital camera files. The company also updated to its Camera Raw plug-in, extending raw file support in Photoshop CS to more than 65 digital camera models and enabling Photoshop CS to handle files in the new .DNG format. The company also launched a free software tool, Adobe DNG Converter, which converts many of today’s popular raw photo formats into the new .DNG file format. Raw files contain the original information captured by a camera sensor prior to any in-camera processing. Until today there has been no standard format for these files, which vary between manufacturers and individual cameras.
