Sigma DP1 picture flaws?

    Look at this photo from a Sigma DP1 beta:

    and look at picture sdim0085.jpg ( second to last ). Get the jpg file
    and look at the picture full scale and look at the bright pink shoe
    sign. It looks like to me the pink of the shoe sign has bled to the
    left and right of the sign. Just like it was a water base print that
    got wet. The same thing can be seen on the yellow sign "What's On" at
    the bottom of the picture. Has this been seen before? Does the SD14
    suffer from the same thing?

  2. I see that too.

    Maybe its a beta firmware, no ? (I did not read the preview even if its an
    interesting camera).

    Here is the crop for the lazy ones:

    Save the jpg and zoom at 200% in what ever you use to see the bled.

    Probably only a jpg engine problem easily fixed with a new firmware I guess.

    More likely sensor bleed, not terribly surprising.

    With giant pixels they have, how would it be possible?

    it's an 'early dp1' with firmware
    yep, not too surprising. there's a nice big yellow blotch to the left
    of the "what's on" sign at the bottom too. there's also a fair amount
    of aliasing on the building. either that or it has some very unusual
    according to the exif info, phil used sigma's latest raw converter on
    those images. unlike some of the other images, phil didn't crank the
    sharpening up too high on that one.

    other images have the usual blotching (which surprisingly, is even
    visible in sigma's dp1 brochure). for instance, on the wall photo,
    particularly in the corners:

    It's clearly visible.
    I'm sure they'll fix it.
    This brings me to another question. What software do you use as your default
    picture viewer - Win XP?
    I use Windows Picture and Fax viewer because it launches fast.
    However I find it annoying that I can't see at what zoom I'm viewing at any
    given time, among other things I'd like to see.
    For that I open up images such as the one you're talking about in PS2.
    Can you recommend another software I could use as default - where I can
    always see the zoom and launches fast?
    How about ACDsee?

    I'mm sure they would have fixed it already if it were fixable. Foveon
    X3 suffers from issues that aren't easy to fix.
    Click the Actual Size icon at the bottom to switch to 1:1 view.
    Check out IrfanView <>

    Firefox will tell you both the image size and the scaling on the title
    bar, and you can install the PhotoME (which also works in Windows
    Picture and Fax viewer) plugin for detailed information. But it doesn't
    advance from image to image.

    Or not at all. We're still talking about a camera that was introduced 2
    years ago and is still not in the stores. I don't think we'll ever see it,
    which is no great loss to any sane person.

    I'm going to download Irfanview.

    I will try to remember to quote below the text.

    Question: Is it possible to double click random images in a folder and not
    have a new instance of Irfanview launch every time I click a new image?

    Yes -- check Only 1 instance in Properties/Settings.

  13. There's no bleeding from the SD14 that I've ever seen.

    In the X3 sensor color accuracy from silicon depth filtering is not as
    good as the sharp cutoff color filters used on Bayer sensors, with
    sometimes strange results, although reports suggest the SD14 is improved
    over earlier models.

    Although it only takes a tap on the escape key to dismiss an image.

    When viewing full screen (hit enter), you can see the zoom by adding this
    -paste that into the box at:
    options > properties > full screen >show text

    and to zoom
    - (minus/dash key)

  16. Apart from the bleeding from the hearts of the idiots that wasted
    their money on buying one of course
