DNG is a universal format for storing and accessing images. Find out more about the history of the DNG file format, what you can use it for, and how different camera manufacturers have embraced the need for change.
What is a DNG file?
DNG means Digital Negative. It’s a type of raw file format used in digital photography, developed on the TIFF 6.0 format. With an abundance of different cameras and editing software on the market, file compatibility has proven a challenge for photographers when sharing and developing their work. The creation of DNG files gives photographers greater control over their images and allows digital camera manufacturers to work to a consistent, open standard.
A DNG file stores uncompressed image data on digital cameras from numerous manufacturers, allowing users to store, share and edit their work without hitting compatibility barriers.
