DNG (Digital Negative Image File)

The DNG Raster image file format

The DNG file format is the universal RAW image format for saving digital photos in an uncompressed format. It was developed by Adobe Systems as a RAW image archival format and is supported by many image viewing and photo editing programs.

Technical details of DNG files

Files with the DNG extension are structured according to TIFF/EP standards. Various formats of metadata are supported by DNG as well. Raw image data as well as image formats not in a raw state are supported by the DNG file, resulting in the occurrence of "linear DNGs" together with the raw version. Even a linear DNG is still able to handle changes made by raw converters, such as color profile, HDR, compositing, white balance, and the like. All programs and applications that support raw DNG files also support the linear type, but not vice versa.
