    Re: polarizing filter

    It is worth mentioning that polarizing filters may cause very undesirable effects when used with wide angle lenses. This is due to the previously mentioned difference in polarization with various angles of the sun. With blue skies, a polarizer can create an uneven effect that may be seen from one side of the image to the other.

    I probably only use a polarizer maybe 5% of the time.

    This may be more a matter of falloff with certain WA lenses that require center filters. I don't recall this being an issue using a Tiffen polarizer (linear) on the Nikkor 90 f8, which I hope you are enjoying Paul.

    This is absolutely an issue with all WA lenses, if the sky is included. The polarizer is at maximum strength 90 degrees from the sun and ay minimum strength when pointed at the sun or 180 degrees from the sun. Since WA lenses typically cover 90 derees or more, if the sky is included the frame can include areas where the polarizer is at both max and min strength. This leads to very unnatural tones in the sky.

    Absolutely. See my previous post in this thread (#28) with a photo exploiting this very phenomenon.

    Old post, I know. But... I will often use my Marumi polarizing filter as a 1-1/3 stop neutral density filter when needed.

    Polarizer and ND have different effects.

    Correct. With the polarizing filter adjusted to minimal effect, it acts as a 1-1/3 stop ND filter. Work for me anyway

    Effects are different: polarizer increases saturation, removes sunlight glares, removes the directional sunlight look, darkens more the blue sky than the clouds...

    it can be used to prevent burning the sky like with a ND graded filter, but with different effects in the image.

    With difuse (cloudy) light a polarizer does nothing to selectively darken the sky, while a graded ND does it.
