Through the Polarising Looking Glass
This week Disney’s 2nd Alice in Wonderland in 3D came out and I had the chance to go see Avatar in 3D… ok that may not make sense to normal people, but the further towards the end of a films run you see it, the more money the cinema gets and the less money the studio gets. I only mention Alice because I wanted a cool blog title.
What I love about these 3DReal films is that they give you polarising glasses. And I wanted to know what kind of geeky fun could be had and I’ve hit upon a surprising use for them:
If you’re a designer or an artist you often have to change the mood of a picture or design, making things more blue, yellow or red to get the right setting. Well using these glasses you just have to tilt your head to the right to make an LCD look more blue and tilt to the left to get a more yellow image. It’s really very cool.

I’m LOLing. My local cable tv office has thousands of those glasses…if you ever need more.
Look out the window at a bunch of parked cars on a sunny day and turn your head. The windows should get darker and lighter as you do so.

Are you sure? The Real3d glasses are circularly polarized. Windshields and regular sun glasses…and LCD displays…and sunlight reflections…are linear polarized.
So what you propose works with normal sunglasses but won’t work with Real3d glasses..and its also why Real3d glasses make horrible sunglasses.
What will actually happen if you are wearing Real3d glasses and you look through a polarized windshield..or even sunglasses…or even at an lcd watchface…is exactly what happened when Martin looked at his screen..
The color change is due dispersion effects associated with different frequencies of light in the circular polarization filters the Real3d glasses use.

Wear Real3D glasses and go look at yourself in a mirror*.
