    Hi mem0riess

    There is a great website where you can learn a lot on DSLR photography. Great for newbies like us. It teaches us how to select ISO for different conditions, adjust shuttle speed, aperture, exposure to obtain different image effects.

    I still quite confused,
    is it that the object nearer to your camera then the "bokeh" effect will come out?

    Guys, the above pics, the focusing point are all quite a distance away, is it possible to do it on D90 kit len?

    The links don't work leh.
    I can't see the photos, so I'm just guessing here.
    By "bokeh effect" (which is the wrong term, by the way), I think you're referring to a photo where the subject is isolated from the background.
    This amount of "isolation" is affected by a few things:

    - focal length of the lens
    - aperture
    - relative distance between the camera, subject, and background
    [I think that's it]
    If it's camera ------------- subject ---------------------- background

    the isolation is less than if it is

    camera ---- subject ---------------------------------------- background

    all other settings being equal, of course.

    I've tried to make it as clear and simple as possible already. I don't think you should be confused anymore.

    Then it's time to use the correct term. There is no "bokeh effect", please get it slowly. What you intend to do is subject isolation by Depth of Field. The distance, focal length and aperture determine how much the background is out of focus and therefore emphasize is given to the subject. Search through the portrait gallery, there the guys work a lot with subject isolation.
    The appearance, quality and pleasing effect of the out of focus area is called bokeh - it's an expression of quality and cannot be measured. It's largely depending on the construction of the lens (lens elements and aperture). But also the colours and objects in the OOF area need to be considered. Lots of shiny colours don't disappear or become less distracting just by having them out of focus. The bokeh will not be good.

    yeah, agreed.

    There is no such thing as BOKEH EFFECT.
    I wish people would stop inventing terms and using them blatantly...

    http://en.wikipedia.org/wiki/Bokeh
    Check out this.

    The term comes from the Japanese word boke (暈け or ボケ), which means "blur" or "haze", or boke-aji (ボケ味), the "blur quality". The Japanese term boke is also used in the sense of a mental haze or senility.[7]

    The English spelling bokeh was popularized in 1997 in Photo Techniques magazine, when Mike Johnston, the editor at the time, commissioned three papers on the topic for the March/April 1997 issue; he altered the spelling to suggest the correct pronunciation to English speakers, saying "it is properly pronounced with bo as in bone and ke as in Kenneth, with equal stress on either syllable".[2] Bokeh replaced the previous spelling boke that had been in use at least since 1996, when Merklinger had also suggested "or Bokeh if you prefer."[8]

    The term bokeh has appeared in photography books at least since 1998.[9] It is sometimes pronounced /ˈboʊkə/ (boke-uh[10]).

    I think Zerocoolastra is talking about Bokeh and Bokeh effect. Yes, everyone knows that there's such a thing call Bokeh.

    Here is a photo I took last year.
    Pardon the lack of composition as I was just field-testing my 50/1.8

    The fact that the flower looks distinct from the background due to the blurring of the background is known as subject isolation due to depth of field.
    The depth of field is thin due to the use of a wide-aperture lens at/near its maximum aperture.
    The out-of-focus areas are the 'bokeh' (or 'haze', as you so adequately translated).

    It is not a 'bokeh effect', which seems to be the cool phrase amongst newbies.
    Bokeh is generally described with words like 'good', 'not good', 'smooth', 'creamy', etc etc.
