Look for a yellow or other colored dot on the back of the filter ring. This dot should face the lens. When the dot is facing the subject the apparent polarization effect is negligible. With the dot facing the lens, the effect is quite noticeable. Can't explain why, but discovered this wheile I was trying to figure out what the reason for the yellow dot was. Mike Swiek
