What is a .DNG file?

DNG stands for Digital Negative, a patented, open, lossless raw image format developed by Adobe. It is designed to provide a standard for raw files, ensuring compatibility and longevity.

Background

The DNG format was introduced by Adobe in 2004 as a solution to the lack of a universal standard for raw image files produced by digital cameras. As each camera manufacturer often uses its own proprietary raw format, DNG aims to simplify workflows for photographers by providing a consistent format. It is particularly popular among photographers who use Adobe software, as it integrates seamlessly with Adobe's suite of applications. DNG files preserve the original image data captured by the camera sensor, allowing for extensive post-processing without loss of quality. The format also supports metadata embedding, which is useful for cataloging and archiving purposes. Despite its advantages, not all camera manufacturers support DNG natively, though many offer conversion tools.

Other meanings of .DNG

The extension .DNG is used by several programs. Besides the file type described on this page, it can also stand for:
