writes Adobe updated its DNG photo format and is pushing it to become the standard for raw images taken by digital cameras:
Currently, major camera manufacturers utilize their own specifications, which are often incompatible and require software developers -- such as Adobe -- to painstakingly add support for each format and every change thereafter. DNG has seem some uptake with companies such as Pentax, but it's not used by Canon or Nikon.
Adobe says the updated specification (version 1.2) brings more flexibility to DNG, responding to industry requirements. DNG now supports the embedding of multiple different camera profiles into a single image file. The result is having different versions of the same photo in a more streamlined manner.
In addition, new metadata tags have been defined for DNG, including a field to indicate the integrity of the raw data within the file, which would let future cameras and software applications validate the image data and possibly fix corruption.
