MacWorld has an excerpt of an article from MDJ about Adobe's attempt to take the confusion out of the raw formats from various digital cameras by creating a standard.

The proposed standard, called DNG (for Digital Negative) is an add-on to the TIFF and TIFF-EP formats that Adobe owns (courtesy of their acquisition of Aldus years ago) and is detailed in the DNG Specification.

The extensions include tags for lots of camera information as well as data about the lens and other attributes.

At the same time, Adobe also released converters for the Macintosh and Windows that convert raw formats from 65 cameras to the DNG format and plug-ins for Photoshop and Photoshop Elements for the Mac and PC.
