![]() I bear no ill will to any camera vendor, and I hope that they'll all be around for decades to come, stimulating competition and innovation, but it's not beyond the bounds of possibility that one of today's vendors may not be around five, ten, or fifty years hence. One of the major problems with camera vendors' proprietary raw formats is that they're undocumented-only the camera vendor knows for sure what they contain. To DNG or Not to DNGĪdobe developed the DNG format in response to a very real concern over the longevity of digital raw captures. My personal bias is that the advantages of DNG outweigh any disadvantages, and using DNG sends camera vendors an important message about the future of digital photography, but it is a bias. It's entirely up to you whether or not you choose to use it-Camera Raw, Bridge, and Photoshop are equally happy with proprietary raw files or DNGs-but the following discussion may help you decide. Real World Camera Raw with Adobe Photoshop CS2Īdobe DNG Converter is a handy standalone application that converts camera vendors' proprietary raw images to Adobe's new DNG format. * The specification allows the addition of private metadata to DNG files, enabling differentiation. * A common format allows greater control over the quality of conversions by third-party applications. * The DNG format allows R&D savings by reducing the need to develop new formats and by simplifying camera testing. * A publicly documented and readily available specification can be easily adopted by camera manufacturers and updated to accommodate technology changes.Key benefits for hardware and software manufacturers: * DNG removes a potential barrier to new camera adoption, since raw files from new models will be immediately supported by Photoshop and other applications. * A single raw processing solution enables a more efficient workflow when handling raw files from multiple camera models and manufacturers. DNG is supported by AdobedlT« PhotoshopdlT« CS5, CS4, CS3, CS2, and CS, as well as Photoshop Elements 9, 8, 7, 6, 4, 3, and all versions of Photoshop Lightroom.Key benefitsKey benefits for photographers: * DNG format helps promote archival confidence, since digital-imaging software solutions will be able to open raw files more easily in the future. Software developers and manufacturers can download the complete DNG Specification (PDF, 486k).

By addressing the lack of an open standard for the raw files created by individual camera models, DNG helps ensure that photographers will be able to access their files in the future.Within a year of its introduction, several dozen software manufacturers such as Extensis, Canto, Apple, and iView developed support for DNG. The solution to this growing problem is Digital Negative (DNG), a publicly available archival format for the raw files generated by digital cameras. ![]()
