“Many photographers work in RAW-format files from their
digital cameras and are frustrated by the many versions out
there—varying not just from manufacturer to manufacturer but also from
camera to camera. But Adobe is trying to solve that problem with its
Digital Negative Specification.
Adobe Systems Inc. in September 2004 introduced DNG, a public format
for RAW digital camera files, along with a free software tool, Adobe
DNG Converter, which translates many of the RAW photo formats (images
before any in-camera processing) used today into the new DNG file
format.
Adobe is also letting any manufacturer that wants to use the format in
its cameras, printers and software applications do that for free
without any limitations in the hopes of encouraging them to accept it
as the standard.
Shooting RAW images means photographers can avoid dealing with the
compression and loss of image quality involved with shooting JPEGs.
But with that change comes the problem that Adobe has addressed: Each
manufacturer uses a proprietary format that is specific to its cameras
and might not be compatible with Adobe's Photoshop or other editing
software.
The Digital Negative Specification, Adobe hopes, will become the
single format, allowing users to store information from a diverse
range of cameras.…”
