what is a dng file

A DNG file is a type of raw file format used in digital photography, developed on the TIFF 6.0 format. DNG stands for Digital Negative. It is an open-source, royalty-free, highly compatible, and continuously improving raw image format. A DNG file is a free open source publication launched in 2004. It stores raw data from digital cameras, which is then converted into other formats like JPEG and TIFF. The DNG file format also allows for the inclusion of proprietary metadata. It is an extension of the TIFF 6.0 format and is compatible with the TIFF/EP standard. A DNG file enables the storage of uncompressed image data on your camera, and after storage comes post-processing in various image editing software programs like PaintShop Pro. DNG files maintain image fidelity and enable future editing while expanding compatibility and saving storage space.
