My SD-9 runined another image with sharpness

Discussion in 'Digital Photography' started by George Preddy, Oct 21, 2003.


    Just look at how the that cracked rubberband the girl's hair ruins the
    whole image. She was spinning around so fast, and the sun was so
    low,I didn't have time to defocus and shoot again. I don't know how
    to blur an image in Photoshop, so now I'm out of luck. God I hate
    this camera.

    I can't quite tell if your're kidding or not. It's a great imagine,
    incredibly sharp with zero artifacts, and I woulnd't bother messing with the
    rubber band in her hair at all. Yeah, you're kdding.

    Use the blur filters under FILTERS -- I would suggest the gaussian, but
    start by selecting the over-sharpened areas and use the smudge tools to get
    rid of the artifacts first. You might also wat to lighten the picture
    overall -- but that will do little about the real problem -- too much

    over Unsharpened judging by the halos,
    and the sensor needs cleaning.

  7. That is a USM-free zone.

  9. I think I agree there is too much contrast, if I remember right I slid
    it to +0.5 during RAW processing. I'm stuck on a laptop right now
    with a crappy monitor --will have to re-develop sometime for a quality

    All SD9 images render flesh tones as yellow. But hey, they're sharp!!!
    Who gives a crap about color accuracy when you can see the hair on a
    zit? ;-)

  14. Scale it up 3 times for the same Bayer blur. Alternatively, use the
    SD-9's 13.7MP mode.

    Take a closer look. Those are JPEG compression artifacts, not USM halos.

    Fercrineoutloud, everyone can see the sharpening artefacts in the
    image. Look at the girl's upstretched hand: can't you see the halo
    around it?

    To my eyes, there is definitely a light-blue "halo" around the edge of the
    hand, which does look rather more like a sharpening artifact than anything
    JPEG should be producing. It's there on the edge of the leaf too, and in
    parts of the hair. IME, JPEG artifacts look more like heat-haze, and don't
    tend to manifest themselves as thin changes in luminousity like this.

    We could be sure if we had access to an unjpegged version (even just a crop
    of the hand holding the leaf), but they certainly look more like sharpening
    artifacts to me.

    It could, of course, be from the lens. I had a Sigma 14mm lens which,
    although mostly decent, did a particularly bad job on high-contrast edges.

  18. SD-9's never render absolute color, so you are actually right. All
    that really matters is the the camera's optical resolution and
    sharpness, color isn't set until the image is developed into any
    number of various originals.

    That particular picture has perfect skin color, I know because I
    personelly matched the shot to the sunset during RAW development. Why
    wouldn't one set the color to match reality perfectly every time? I
    think you are confusing the SD-9 with a JPEG shooter.

    Well, these look like sharpening artefacts, and result in an artifical
    sharpness. I've no way to know what software is doing it, of course.
    or even a well JPEGged version. JPEG doesn't require nasty artefacts.
    Yup. Reckon the SD9 conversion is doing some sharpening, even if
    George doesn't realize it.

    I've just noticed that there's a larger version of his photo there as
    well, which is much less compressed & shows this stuff a lot more
    Looking the little girls hand that's holding the leaf, there's
    definitely a lighter border around it. Looking at this makes me think
    that you might be correct about it being sharpened. OTOH, her hair
    doesn't look sharpened at all. Looking at the really awful bokeh in the
    out of focus areas of the photos (llok at the flowers & the leaves in
    particular), I can't help but wonder if the problem is mostly due to a
    crappy lens.
    Looking at the larger image, I suspect that your guess may well be
