    Hi , Is using a polarizer as simple as just fitting it on the front of your
    lens ?

    Pretty much. You turn your polarizing filter much the same way you would
    focus. This is so you can set it to take the picture with as less glare as
    possible

    I find it's good for getting a deep blue sky, and cutting down on
    reflections in water and on leaves - you rotate it to get the best effect.
    It also depends on where the sun is in relation to what you're shooting.

    Almost...you also need to rotate it to achieve desired effect. Plus
    there are a few rules to remember.

    1. Polarizers only work at right angles to the sun.

    2. Polarizers can not reduce reflective glare from unfinished metals.

    3. Polarizers reduce light transmission by about 2/3 to 1 f-stop in
    most cases, perhaps more depending on the particular make/model of
    filter...and if your camera can not automatically read the reduction
    in light, you need to make a manual correction (most modern cameras
    can make the exposure correction with their own internal light
    meters).

    4. Polarizers don't always improve a picture...in some cases, when
    possible, you may wish to shoot the same scene both with and without
    the filter to see the difference in the finished slide, print or
    on-screen image.

    5. If you are using an autofocus system, you need a "circular"
    polarizer, rather than the linear type. Manual focus cameras work
    with either type...but there is something about the autofocus sensors
    that don't work properly with linear polarizers.

    If that is the case you got stung with a cheap polarizer. Or you habve somehow
    delaminated the darned thing..

    You have to turn the outer ring while looking through your viewfinder,

    Only one piece of glass on my polarizer too, this is attached to the outer
    ring that turns.

    I only have one piece of glass in mine as well...looks like a trend
    developing!
