What is a DNG file?

A DNG file is a RAW camera image saved in the Digital Negative (DNG) format. It stores uncompressed image data captured by various camera models, such as Hasselblad, Pentax, and Leica. Professional photographers commonly use DNG files because they maintain high image quality.

Adobe Systems developed the DNG format to be a universal RAW camera format that would enable digital photographers to store, share, and edit RAW images more easily. The company released the format in September 2004 and made it publicly available to allow for wider adoption among camera manufacturers and image software.

Since its release, the DNG format has become one of the more common RAW camera image formats. Some other common formats are Canon Raw Images (.CR2 files), Sony Digital Camera Images (.ARW files), Kodak RAW Images (.DCR files), Nikon RAW Images (.NRW files), and Nikon Electronic Format Images (.NEF files).
