    Hi ~

    I have a kodak camera, P 850. (which I've outgrown).
    Is the kodak software better than dcraw or ufraw to decode raw .KDC files?

    Since I live with the penguins in linux-land, I have no idea of how the
    bundled software compares to dcraw for decoding the proprietary raw
    formats.
    The camera's thumbnail might look crisp, but after a dcraw conversion
    (to ppm=Portable PixMap ) the image shows lots of noise - in poor light
    conditions - like a moon shot, or night landscape. I've tried tweaking
    various parameters during the raw conversion, black level, brightness,
    etc, and post image tweaks.

    In decent light and proper settings, dcraw does a fine job from either
    the command line or gimp plugin.
    for some reason ufraw (with gimp) does a horrible job with KDC's, even
    in the best of conditions.

    I'm not sure which decoder ShowPhoto uses, but it decodes fairly well
    and it extracts more meta info than dcraw.

    If you're using any form of auto mode, the camera probably boosts the
    ISO in low light, and as with any small sensor camera, this is going to
    give you noise. Try forcing low ISO (50 or 100) for some low light
    shots (on a tripod!) and see how you get on with dcraw then.

    I would expect noise to show up more in shadow areas anyway.

    It's possible that the in camera jpg processing does noise reduction,
    but this tends to blur details anyway.

    I've been getting excellent results with ufraw on my ubuntu laptop and
    tower from my P850. I hope to have some posted soon.
