    DNG 3.1 has been posted and will convert D2X NEF files to be used in CS
    or CS2:

    ACR 3.1 can be used in CS2 but not CS:

    Are people using the DNG thing to convert & archive RAW files? I didn't
    know there was a converter. A lot of extra work but I guess it's wise.

    One practical reason is that compressed DNG is 12 to 25% smaller file than
    compressed NEF. Not much extra work as DNG will batch convert a folder of 100
    D2X compressed NEF in well under 10 mins on a 3Gig P4 with 3Gb RAM.

    I think DNG will be around for a long time.

    This is actually the CS2 version, move up one folder for the CS.

    This works pretty well. I just tested 18 NEFs & it took about a minute
    or less to convert; much quicker than transfering from CF card! It
    reduced my D70 5MB NEFs to 4MB DNGs. 20MB savings for that small set of
    shots & I suppose this ought to be a more stable archive format than NEF
    20 years down the road I can guess which will be better supported.

    I wonder if this disables some of the Nikon "goodies" in Capture or NV
    though I don't use those. I know there are some EXIF fields that PS
    doesn't read properly.

    Breeze Browser trial only shows thumbnails & the convert button is
    greyed out. I'd guess DCRAW supports this format??? but I wonder if I'm
    sort of locked into using photoshop or other programs would support it.
    I might not always have a full PS license available. With Nikon & Adobe
    in a spat lately over the DX2 WB encryption, I wonder if they will try
    to sabotage this format, especially if it locks users into Adobe converters.

    Any other caveats I should know about?

    Paul Furman Guest has a huge, intensely detailed discussion. More than I
    could absorb actually.
