I know this may seem like a completely stupid question to ask here but i don't care!! :bonk:

I have a 72mm Hoya circular polarising filter that i use on both my Lenses. I was kinda talked into it and bought it. Because i like to snap a lot of cars and planes, it sounded like something i should get.

I'm sure this white marker you can on the rotating part of the filter has some significance, can anyone tell me if this is so?

And how can i use the filter to achieve the best results?

It's like this one....

Thanks :)
 
As you rotate the outer ring (the rotating part) it will reduce/remove reflections (or darken skies) BUT its a very subtle process so you need to rotate very slowly to see the effect.

These questions are great, you know why? Because there are several people out there that want to ask but darn't....:D

Your question's been answered....:thumbs:
 
Think the white mark is supposed to be turned into the direction the light is coming from but in practice you just wouldn't bother looking at it and just turn it until you get the desired effect.

A polariser will work differently at different times of the day and different directions of shooting so you will always have to rotate it as you move around changing angles. It will always do something for reflections but will not darken the sky when the sun is directly overhead or in front/ behind you.
 
Thanks for the wise words guys! I've always been a believer that you should ask if you don't know, no matter how stupid a question you think it is...

I asked and now i know! :D (and i didn't get called a pillock)
 
Pillock!





:D Sorry, couldn't resist. As Matt says, the only stupid questions are the ones you dont ask, and I bet this question has been answered for many. :thumbs:
 
A polariser will be most effective when you are shooting at right angles to the direction of the light. Be careful with wide angles though because you can get different degrees of polarisation across your image.

to see the effect, take if off the camera and look through it at water or blue sky near the horizon, then simply rotate, works like the old polaroid sunglasses.
