Just got my new multicoated Hoya circular polarizing filter in. I took it out and was holding it up to my eye just to see if I could tell a difference. All it did was make everything look darker. I took it outside and, yes it is cloudy, but I couldn't tell that it made a huge difference. What was more disturbing, I tried turning the thing in my hand like I was told you are supposed to do and, nothing. No difference whatsoever! Is this thing gonna work better on my lenses?

the effect will be most prominent at 90 degrees to the direction of sunlight.

or look at glare reflected off a smooth surface at about 45 degree.

I had the same experience with my new Hoya CP filter - I saw no change in the sky or reflections as it was rotated while holding the filter in my hands and looking through it. What I discovered is that I had been looking through it backwards. When I turned the filter around so that the male threads were on the same side as I was, then it worked the way it should have. Mounted on the camera it works fine too.

Are you supposed to actually "see" threads in the glass? Looking at the filter all I see is a tinted peice of glass. I checked both sides as well.

I am hoping tomorrow will be sunny so I can take it for a test drive!

He's talking about the threads on the metal ring holding the glass. Put the male threaded end towards you and the female threaded end towards what you're looking at.

CPF can be very tricky, and it steals a lot of light. So it's not on my lense for any security reasons what so ever. But when the conditions are right, it can be very fun to put on your lense.

You won't see any effect on cloudy days. Polarization shows up in the sky on clear days in a plane 90 deg. from the axis of the sun.
