I've mentioned I own a polarizing lens.

Someone mentioned it was good for taking the glare out of water as well as giving the sky a funky colour and I want to try this, but here's my question.

Are you ready for it?

My lens has a little white line which (I assume) is for me to aim at the sun to get best results. So what way do I point it when taking pictures of water? At the sun or at the water?

Colour me confused.
