DNG vs DDS:
|Full name||Digital Negative||Microsoft Direct Draw Surface|
|Developed by||Adobe Systems||Microsoft|
|Type of format||Raw image format||Texture files|
|Introduction||Digital Negative (DNG) is a patented, open lossless raw image format written by Adobe used for digital photography. All Adobe photo manipulation software (such as Adobe Photoshop and Adobe Lightroom) released since the launch supports DNG. DNG is based on the TIFF/EP standard format, and mandates significant use of metadata. Use of the file format is royalty-free.||The DirectDraw Surface container file format (uses the filename extension DDS), is a Microsoft format for storing data compressed with the proprietary S3 Texture Compression (S3TC) algorithm, which can be decompressed in hardware by GPUs.|
|Technical details||A DNG file always contains data for one main image, plus metadata, and optionally contains at least one JPEG preview. It normally has the extension "dng" or "DNG". DNG conforms to TIFF/EP and is structured according to TIFF. DNG supports various formats of metadata, (including Exif metadata, XMP metadata, IPTC metadata), and specifies a set of mandated metadata.||The DirectDraw Surface format is useful for storing graphical textures and cubic environment maps as a data file, both compressed and uncompressed. The Microsoft Windows file extension for this data format is '.dds'.|
