    Is there any way to create a dng file other than using PS? I've looked and
    can't find any. I be particularly interested in a Linux solution. Is it
    the case that Adobe is keeping this a proprietary format?

    Hi Ray...

    Take care.

    dng - that's the Adobe Digital NeGative format.

    Hi Ray...

    Arghhh, sorry about that. I have to learn to think before I start
    typing.... one of the disadvantages of getting old, I guess.

    Adobe has a couple of (free) converters on their site, for Windows
    and Mac. Unfortunately so far nothing for 'nix.

    Take care.

    Maybe the PC version of the free Adobe DNG converter will
    run under WINE, got to be worth a try.

    If that were so they wouldn't have bothered to fully
    document it and even provide free SDKs for the platforms
    they support. Adobe support only Mac and Windows so if the
    Linux community wants a SDK converter it's up to someone to
    write one - all the information is already in the public
    domain.

    A couple of camera makers with little market share are making DNG their
    default output file format. More RAW converter programs are *reading*
    DNG now but so far as taking a RAW file and converting it to DNG I
    think Adobe is still the best (only?) bet.

    It's not a proprietary format so someone could make a Unix converter.
    But demand for a DNG - UNIX/LINUX solution is probably so small that
    few would deem it worth the effort.

    Thanks for the info. I have only recently started digging into this, and I
    was not aware of those resources.

  8. No. DNG is not proprietary. Any one can use it. As to why Adobe hasn't made
    DNG for Linux the answer is simple why bother. The vast majority of Adobe's
    user base either uses Windows or to a much lesser extent a Mac. I seriously
    doubt the geeks that use Linux even hardly registers on their radar and
    certainly not enough to spend the money to convert.

    I just tried the Adobe DNG Converter in Wine on Ubuntu 6.1 and it worked
    fine.(.cr2 files from my 400D) Now the question,what can you do with
    ..dng files in Linux??

    Whatever you do with any other raw file ;-)

    The main advantage is size and standard metadata and
    workflows compared with the proprietary originals,
    especially if you use several different camera brands like I
    do. Dcraw (and anything that uses it) can of course handle
    DNG, as can handy utilities like Exiftool.

    There are a number of programs which will read the raw files - bibble,
    lightzone, ufraw, gimp. I'd really like to be able to convert some old
    tiff and jpeg files and fradiddle them with ufraw.

    I tried loading the .dng files in Gimp 2.2.13 and it didn't like em at
    all.finally opened a pic it claimed to be 276 pixels wide?? No problem
    in Lightzone or Rawshooter but those were Windows progs.Didn't think to
    try Ufraw with .dng.

    Never mind,duh,open in Gimp without Ufraw..kind of skipped a step there

    Circular reasoning.

    Few Linux users use Photoshop, etc because it's not available on Linux.

    We should also note that DNG is indeed a propreitary format,
    which is controlled and maintaind by Adobe. The fact that is
    is published does *not* make it an "Open Standard".

    The supposed problems with not being able to find software to
    support the various formats used by camera manufacturerers is
    not different than Adobe not providing a DNG converter for other
    than Microsoft and Apple based systems (in essense, only for
    Photoshop).

    DNG is mostly just hype by Adobe to shift advantages from one
    aspect of engineering from the makers of image software to the
    makers of camera hardware. It would be to Adobe's advantage,
    but not an advantage for a manufacturer.

    It makes virtually *no* difference to the camera user, in
    theory. Of course if a significant majority of cameras actually
    did use DNG, Adobe would then be able to leverage their
    position, and users might well suffer, right along with
    manufacturers and competitors.

    Adobe of course is hoping that by marketing DNG to users that
    they can cause manufacturers to follow.

    About 8-9 years ago Adobe ported Photoshop (probably 4.0 at that time)
    to Unix, thinking there might be a market for it for people with high
    powered workstations ... the sales were so insignificant that Adobe
    didn't bother offering new versions though.

    I'm sure a lot of Unix/Linux users would like to have Photoshop but
    would they actually pay for it in enough numbers to make it worthwhile
    for the vendor? Probably not ...

    Adobe ported Photoshop to Unix platforms until version 3, IIRC.
    They extracted a fee (extortion you might say) to pay for porting efforts.
    I believe SGI was the last company to pay that porting fee.

    The Wikipedia article on Photoshop agrees with my recollection of 3,
    so if it's wrong, please correct us Bill.

    If it works, they'll pay. There are plenty of people running it via
    Wine. And plenty more who want to, but can't configure Wine well enough
    to get it to work.

    Here is about 15-20 pages on the subject of DNG. I'm coming to this
    thread late, having been out of touch over Christmas, so I won't try to
    respond directly:
    http://www.barrypearson.co.uk/articles/dng/

    PS is one software product that can't create a DNG file! But the ACR
    plug-in can. So can various other products. Most DNG conversions use
    one of the Adobe products, and they don't run directly on Linux - hence
    WINE, as others have said. (There are several other DNG Converters
    written by other people, and several other products that write DNG
    files, but typically for specialist purposes. DNG is so open that even
    Adobe don't know all the products that have been written to support
    it).

    DNG is as open as TIFF. So if you are satisfied that TIFF is open, then
    so is DNG. Whether it is an open standard depends on your definition of
    "open standard". See the following article:
    http://forums.dpreview.com/forums/read.asp?forum=1000&message=20055362

    In response to: "There is no independent non-commercial body governing
    the matter", this response is:

    "That is not a requirement for open standards. The man who coined the
    term and founded "The Open Group" laid down the definition that the
    only requirements are that the standard documentation and whatever
    intellectual property is required to implement it (patents, copyrights,
    etc) be available to anyone on a RAND (reasonable and non
    non-discriminatory) basis.

    "Later government agencies like the ITU and the EU trying to push
    varying agendas started adding all sorts of cruft about committees,
    because they are committee organizations that exist to propagate
    committees".

    By that definition, DNG is open. DNG is supported in some way by more
    than 140 products from more than 130 companies. There is no attempt to
    lock-in to Adobe products.
