Linux and RAW file format conversions

    I was in need of a Pentax RAW file conversion utility and found it here:

    It has the ability to read numerous camera RAW files, not just Pentax

    It's free for Linux and also available for those other two operating
    systems (at a cost).

  2. It is called lightZone. It is not just a raw file converter but also works
    as an image editor. It is very much different from other image editors in
    the sense that it works by zone system. Each zone of brightness can be
    manipulated independently, a very sophisticated combination of levels &
    curvs for other image editors. However, other image editing facilities are
    quite rudimentary and there are few controls during raw file conversion. I
    tried it but was not very impressed overall. For me Ufraw still remains
    the best raw file converter for Linux.

  3. The RAW converter in lightZone is dcraw (from Dave Coffin),
    which is of course the exact same RAW converter used by UFRAW,
    except of course UFRAW uses a built in copy of dcraw and allows
    significant image manipulation during the conversion process.
    It is interesting, but I see absolutely no reason to change from
    using UFRAW and The GIMP.

    LightZone (and nearly all other Linux raw readers) uses dcraw to read and
    decode the raw data files. Other options include ufraw (most definitely
    worth a look - IMHO), bibble, and vuescan. You can also use dcraw by
    itself to do a batch conversion of a large number of raw files.

    Yeah, I've been digging ufraw recently and its ability to run from the GIMP.

    I'm still sorting things out, myself, but I'm impressed by the ability of
    dcraw standalone to do a batch conversion.
    ray, Feb 3, 2007
  7. UFRAW also does batch conversions, and because of all the facilities
    it provides, it is probably nicer than straight dcraw.
    Floyd L. Davidson, Feb 3, 2007
  8. Bibble ( also offers an editing system that runs
    under Linux and supports many different RAW formwats. I don't know if dcraw is
    at the heart of the RAW converter or not. I rarely shoot raw, but I've gone
    back and forth between UFRAW (gimp plugin) or Bibblepro. Note, the Linux side
    of bibble is a little buggy, particularly if you use the Noise Ninja option,
    but if you are willing to try for-pay software, you might want to try out the
    free time-limited download.

    That's not something I've seen yet with ufraw - could you explain how it
    ray, Feb 4, 2007
  10. Along with /ufraw/ you get /ufraw-batch/, which runs as a
    non-GNU command line program, but is otherwise the same. An
    example of usage would be if you have a directory full of RAW
    files that can all be processed in virtually the same way...

    Run /ufraw/ on one RAW file. Along with other adjustments, when
    finished do a "save as" and set the options to save the ID file
    and/or to save image defaults.

    Saving the ID file produces a *.ufraw file with all of the
    options set, and "save defaults" will put them into ~/.ufrawrc.
    I haven't checked to see exactly what differences there are
    between the two files, so I'm not sure about what sort of minor
    variations there might be from using one instead of the other.

    But if /ufraw/ or /ufraw-batch/ is then executed, the defaults
    in ~/.ufrawrc will be applied. Or, either can be started with a
    command line option like this to override the draults and use an
    existing ID file:

    ufraw-batch --conf=d2x3251.ufraw *.nef

    Where "d2x3251.ufraw" is the existing ID file generated manually
    using the GUI invocation, and it is expected to process all
    "*.nef" files in that directory.
    Floyd L. Davidson, Feb 4, 2007
  11. The ufraw man page and ufraw --help both mention the program

    ufraw-batch [OPTIONS] <rawfile(s)>

    The help output says:

    UFRaw first reads the setting from the resource file $HOME/.ufrawrc.
    Then, if an ID file is specified it setting are read. Next, the setting from
    the --conf option are taken, ignoring input/output filenames in the ID file.
    Lastly, the options from the command line are set. In batch mode, the second
    group of options is NOT read from the resource file.

    I didn't forget it, I never heard of it. Will check it out. What might
    it's main features be?

    Its incredibly slow speed. Unusably slow IMO, which is a
    shame because it's quite well featured otherwise.

    It looks like every time you move a slider and change a setting it
    recomputes completely the entire image (demosaicing, colour correction,
    noise filtering, sharpening etc.), which takes approx. 10 seconds on my
