What is it?
DNG (Digital Negative) is Adobe's open standard for RAW image files. It was created to address the fragmentation problem caused by hundreds of proprietary camera RAW formats.
DNG is a universal RAW format that stores all the unprocessed sensor data of a camera RAW file in a standardized, future-proof container that any DNG-compatible software can read.
Technical Specifications
Pros & Cons

DNG files include an embedded JPEG preview for quick browsing.

Most cameras do not shoot DNG natively - you must convert proprietary RAW files.
Converting to DNG adds an extra step to your photo import workflow.
Some software and plugins work better with native RAW formats than DNG.
