Need help obtaining a certain 'look' to my photos..help appreciated

  1. Hi all,

    As per the subject, I'm VERY new to digital photography, and have purchased
    a Kodak DX6340 which I feel is a good camera for me to start with. If I try
    to photograph a waterfall, or someone in motion and want to create a
    'blurred'
    motion effect, it seems that the shutter speed is too fast, and just freezes
    them.

    I tried the PAS (program/arperture/shutter priority) modes, and set the
    shutter
    speed to about 4 secs. When trying this to film a moving subject where I
    wanted
    a motion blur (or waterfall) it was so overexposed the picture was just
    white.
    I'd love to say film a child running a race, but the background is blurred.
    Also, I
    really want to try and film say the motion of cars on the freeway, or a
    waterfall.
    I tried filming the cars at night and used a tripod..I got some good
    effects, but
    can the same effect be used in the daytime? eg you see a city skyline and
    freeway,
    but the cars all 'blend in' with one another.

    So I'm sure there are plenty of people out there who could perhaps steer me
    in
    the right direction, either in the form of a website or perhaps some tips?

    All help/tips/info is GREATLY appreciated!

    Cheers

    you want to try the lowest iso setting you can, combined with the "biggest"
    aperture setting. ie perhaps F8 is your maximum?

    blurred.

    here you can the lowest aperture you can have, ie F2. and be quite close to
    the subject when you take it.

    if theres too much light then no. your camera would not be able to do it.

    eg you see a city skyline and

    Clearly when you extend the exposure to that extent, you have to deal with
    the increased amount of light gathered during the exposure. First thing is
    to make sure you are at the minimum apeture of your lens, that is, the
    maximum f-stop. You may also be able to set the ISO rating - you want it to
    be the lowest possible. Even then I doubt that will stop the overexposure.

    The only solution then is neutral density filters - I don't know if they are
    available for you particular camera, but if not, you can experiment with
    simply taping what filters you can get over the front of your lens. This
    will effectively stop down the light entering the lens. NDs generally come
    in 1, 2 and 3 stop values - confusingly referred to as ND 3, 6 & 9. If you
    can't get a decent exposure with an ND 9, you can screw them together to
    increase the light reduction.
    blurred.

    This isn't so difficult to achieve, even at relatively fast shutter speeds.
    You need to go to maximum zoom and track the subject - if the shot is too
    tight, don't zoom out, rather move backwards to get the desired framing.
    You'll get the best results in this situation by using a fluid-head tripod
    that will allow a smooth pan as you follow the motion.
    Unfortunately this is difficult to achieve - even using ND's or other light
    reduction methods, since an exposure long eough to capture the moving car as
    a nice strong blur will tend to over-expose the static elements of the
    scene, causing both blown-out elements, and a ghostly effect to the blurred
    car.

    Try setting this ISO speed as low as it goes, perhaps 50 or 100. If you can
    set the F-stop manually you might need somthign pretty small like f/11. You
    shoudln't require a shutter speed as slow as 4secs, more like 1/4sec would
    be plenty.

    Obviously, bring the tripod.

  5. Buy a digital Cokn Filter adapter and then by a Cokin Neutral density filter
    probably a x8. This will release the amount of light available without any
    colour cast and produce slower shutter speeds. Don't forget the tripod :)

  6. Pan and track the child/car/movng object as you take the picture. You will
    probably have to set the focus to manual as autofocus will not keep up. This
    is how they produce photos with sharp subject and blurred background.

    This is pretty basc stuff, checked out your library for photography books?
    The principals apply to any style of photography


    A lot harder but then the Cokin filter willl help, possibly combining two
    ND8
