What's gone wrong.

Okay it's 17.00 hrs. Just tried the finger thumb trick and can see how that works.
Pointed the filter at the sun - rotated the filter - could see no difference.
Pointed the filter at a few clouds to the side of the sun - rotated the filter - could still not see any difference.

When I do the pointing at the computer screen as you have said earlier I can see a difference when the filter is rotated.

The filter by the way is the Hoya Pro.

Your still not using it correctly.

Okay, I guess I am in the thick club.

So in plain english how should a circuler polarizing filter be used. Screw it into the lens then ?????????????????.

Many thanks.

Turn it whilst looking through the viewfinder. You will clearly see the effect. If you are looking at blue sky, it will get bluer, if you are looking at water or glass, the reflections will vanish. As you turn, the effect will get stronger, until it goes back to how it was again.

Again, you need to be the right angle to the light source. Pointing it at the sun will have no effect, as the light rays will be coming straight towards you, you need to be at an angle to the sun for it to work.

Thanks you, now I've got it.
