Here’s an educational video that provides a helpful visual demonstration of what a polarizing filter can do for your photographs.
“Polarization” is not “direction”.
Coming from a gay guy, she’s very pretty.
As a physics teacher, if one of my students explained the phenomena of polarisation in that way I’d crucify them
Olivia is very pretty presenter, but you`d better turn sound off. Text of this presentation is awful.
She gets a bonus for initiative, effort and above average aesthetics!

Agree with the others that said that the principle that she is explaining is wrong… If I didn’t know what polarization is, I think that this video would confuse me even more. “Block light from one direction”, so will it block the light coming from above? Or from below? Or from the left? That’s not what polarization is…
Think she explained it kinda easy for people to understand it. I don’t know how to explain it different without getting into to much technology humbo jumbo. :/
Since it is both video and voice you see that the light ‘waves’ are cut out from an angle in the video and not light from above, below, right or left (like a gradient ND filter should do).
A little while ago I created an episode on polarizing filters with a bit more emphasis on how they work: http://www.youtube.com/watch?v=X6yjMqDCp0s
Good but I’d challenge “light coming from one direction”. My physics teacher would horrified! :-)
