Digital Negative (DNG)
Be interesting to know how "open" this format really is. Adobe is not known for its charity.
An open raw image format would be valuable.
Update: Slashdot coverage was very positive about Adobe's spec. It's an extension to TIFF, basically it's a spec for metadata that describes the RAW file and a spec for embedding that metadata in TIFF. I think it might even be applicable to compressed files (JPEG2000, JPEG) wrapped up in a TIFF wrapper. It may give TIFF new life. Sounds like a real plus.
