The International Standards Organization this month published Adobe's Digital Negative format
as the international standard for raw image capture. I don't know whether this will induce more camera manufacturers to migrate from their proprietary raw formats to DNG, but if they did it would certainly simplify the process of supporting recently-introduced cameras by raw conversion software and, I suspect, encourage the development of new image-editing tools. It would also increase the archival potential of raw images; I know from conversations in the past with representatives of the U.S. National Archives that one of the greatest obstacles to the preservation of digital data formats is the continued availability of commercial products that are capable of decoding them.
