instructables.com — "By using a pair of polarizing filters and a property of certain materials called birefringence we can photograph the hidden stresses in hard plastics. This instructable was inspired by this article and a comment I read in another instructable, somewhere, about LCD monitors and polarization."

cool but useless!

i think what rmetzger meant was how you can use a polarized filter to reduce glare, for example on asphalt or the surface of water. also different parts of the sky have different polarizations depending on time of day, humidity etc. so you can get really high-contrast photos of clouds by using polaroid filter. if conditions are right you can also photo something below the surface of water since a lot of the reflected light is polarized.

Would be cool as hell if I was tripping balls on acid or something.Dugg.

do a petrography course in a geology degree and you will very very quickly learn that as cool as birefringent materials can look under crossed poles using it diagnostically along with other interesting optical features (pleochroism is also cool) is anything but ethereal

buried as inaccurate. nothing to do with Ethereal/sarcasm

Two polarizing filters with slits oriented at a 90* angle to each other can do wonders for ugly people.

I don't understand why everyone is so thrilled with this. I'm not an engineer and maybe I can't appreciate what exactly was accomplished.

Taking photos is fun.
