    Default Camera setting when using circular polarizer

    Hi i remembered reading one of the thread someone mention that he cant get the blue sky effect using polarizer then someone pointed out that his camera setting is wrong. Im unable to find the thread anymore. Am wondering issit we should not set auto white balance or turn off active D lighting?

    When using a colour effect filter you need to switch off all automatic correction functions - otherwise the filter effect is going to be "corrected". "Daylight" gives good results, but "Cloudy" also works well with CPL when taking images of clouds at 90 degrees from the sun at sunset.

    Either Cloudy or Daylight Setting. You may try Cloudy setting as it gives you a warmer look.

    first thing, need a sunny day sky to begin with,
    second, the position of the sun should be on photographer's left, top or right, not facing the sun or the sun is right behind him.

    third,need to rotate the CPL filter ring to get best effect.

    lastly, if it is a sunny day, the WB can be auto or daylight.

    please remember to compensate the darkened 1-2 stops...

    the auto-exposure will do that for you....

    is there a reason why the sun have to be on the left?

    btw, i saw a little white triangle on the CPL filter, what does it indicate?

    Read again, it can also be right or top. But is should be about 90 degree from the direction you are aiming with the camera. Reason is the way how reflected, polarized light hits the filter.
    More details in Wikipedia.

    Indicating plane of polarization of the filter. Usually you don't need to worry about that. Look through viewfinder and turn the ring till you get the desired effect. I guess it's left over from the Linear Polarizers of the film era.

    depends on CPL maker... Tokina the meter would read properly.... Hoya would read as the same without CPL... never tried other brands though...

    Are you sure that you use a Circular Polarizer and not a Linear Polarizer? I have 3 different CPL from different makers and none of them gives odd metering results. Each will give a different loss of light, though. But the Program Automatic function will correct this properly.
