    Hey guys,

    I just got my Bay II step up and poloarizer filter. It's cool that it jives with my camera. However.. what would be the best technique to use it? Putting it on viewing lens and rotating it to the darkest option, then carefully moving it to taking lens? The only thing that might be a problem is letting rotate while taking it off to move to lower. Any one a fool proof way of doing it? Oh.. I guess being the darkest point on filter is the best? been away from filter use for a while.

    Doesn't the circular polarizer have a position marker (dot) on the rotating part of the filter ring? If so, make note of the position before you remove it from the viewing lens... and when in place on the taking lens rotate the marker to the same position. If not, use a Sharpie marker and put an marker on it.

    Great.. I pointed it toward computer screen and what a wierd affect.. It makes the projection completley disappear. I guess the optimal position would be at the darkest point?

    It all depends -- sometimes you don't want the highest level of polarization, or if there are multiple reflective surfaces (like a desk in an office with a glass partition) you will need to adjust the amount of polarization to the desired effect.

    Try using a polarizer in bright sunlight outdoors with polarized sunglasses and watch everything go dark!

    The factory polarizers for higher end old Kodak cameras had a viewing glass on the end of an arm that rotated with the polarizer over the taking lens,. You looked thru the viewing polarizer to see what the big one was doing. Kind of a cool system.

    Just hold it over the viewing lens, and rotate till your desired effect. Once that's determined, hold the filter over the taking lens. Crude, but it works most efficiently.

    P.S. the original Rolleipoll polarizer was a linear one with markings on the outer ring to help one orientate it when removing it from the viewing lens and putting it on the taking lens
