cool! interesting demo

nice video ;)

but there is a mistake in CPL part.. when you towards the 1/4 waveplane to your screen, we should get no change in light intensity, just opposite your explaination.

thank you for this video. It illustrates Birefringence very well.

nah, its sold like a filter, it just screws onto the outside of the cameras lens. most camera shops sell them for less than $10

Cool... *adds to shopping list*

Hey, cool video! Did you have to dismantle your camera to get the filter out?

@Pastbyer thanks all, no i didn't have to take apart the camera. camera shops sell polarizing filters for a few bucks.
