    Default No0bie question and thinking.

    I have a CP5700 and since it's 8x zoom my mentality when coming to take macro shots is to

    1) Zoom out to max 8x
    2) Attach a Hoya +4 macro filter

    The problem is that the subject is always blur, I have to zoom out to get a clear pic... then move near to get a shot... I scared away a few dragonflies last sat at BG... wonder if that's the way to use macro filters.

    Attached them then move near, not attached and zoom ?

    Another problem I have is with the aperture values.

    The larger the aperture the more light? Or smaller the aperture the more light?

    Smaller aperture blur-er background, larger aperture clear-er background.

    Anybody can explain?

    Normally on bright days I set my aperture to abt 2.9-4.1f.

    cool... aperture means hole, so extrapolate the larger/smaller
    larger hole means more light means come from more directions means blurrer.

    when using big zoom, and closeup the DOF will be very short, so reduce the aperture lor...

    I presume DOF = Distance of Focus?

    Okie, will roger that, but sometimes I'm unable to change the aperture, funny, when it's at 1/60, the aperture rests at 4.1f. which is funny and sometimes I can get 2.9f.

    Maybe I should read the manual more ?

    How far away is your camera lens to the dragonfly ? Post a shot with settings to let us see. Using a closeup filter , the focusing distance is always fixed .. ( different camera got different focusing distance ). Try to position your camera ( set to 8x zoom , macro mode off ) with closeup filter for a distance from 20cm - 25cm to focus ...



    Attached them then move near, not attached and zoom ?
    ????? What are "them" ???




    Another problem I have is with the aperture values.

    The larger the aperture the more light? Or smaller the aperture the more light?

    Smaller aperture blur-er background, larger aperture clear-er background.
    smaller aperture value e.g. f2.8 is BIGGER HOLE .. of course allow more light ( more blur background )

    bigger aperture value e.g. f8 is SMALLER HOLE .. allow lesser light ( less blur background )

    the dragonfly looks soft to me ... try this

    - wait for better lighting ( brighter sun )
    - use smaller aperture like f8
    - dun use 8x ... use abt 6x to take the whole dragonfly
    - watch out for distracting background
