I need someone that is going to see Avatar 3D to do an experiment for me.

While watching the movie, take your glasses off and look through them upside down, so that your right eye is looking through the left lens, and your left eye is looking through the right lens. Then come back and tell me what effect you see. I'm guessing that everything will look blurry and out of focus, but I'd like to know for sure.

Thanks,
Shawn

While watching the movie, take your glasses off and look through them backward, so that your right eye is looking through the left lens, and your left eye is looking through the right lens. Then come back and tell me what effect you see. I'm guessing that everything will look blurry and out of focus, but I'd like to know for sure.

I'm not really good at explaining, but you will see the same thing, except mirrored.
A pair of 3D glasses filter out light that is supposed to go to your other eye. Think of the video as in two layers. One blue, one red. Now, for example, red is destined for your left eye, and blue for your right. Therefore, you will have red glasses in front of your right eye (to filter red), and blue glasses on your left (to filter blue).
If you reverse it, all the blue will go to your left eye, and red to your right, mirroring it.
 
They aren't using the red/blue system anymore. It's something to do with light polarization.
 
If you live near a metropolitan area with a Sony Style store you can check it out.
They have their Sony 3D demo out (I just saw one for the first time this weekend) complete with glasses. I guess by July their going to roll them out for 3D programming.
 
the glasses looked to me to be of the red/blue variety. while there certainly have been some other tech advances, the basic red/blue of the glasses still seems to be necessary.

i forgot about this, so didn't switch eyes. but w/o the glasses, much of the screen is indeed blurry.
 
Sorry I didn't see this thread before I watched the movie but I must say, see it in 3d. It was awesome. I highly recommend it.
 
The glasses are polarized at two different angles, 90 degrees off from each other. Each blacks out alternating frames, so the right eye sees half the frames and the left sees the other half. Without the glasses, each eye sees all the frames, giving a moderately to severely out of focus image, depending on how much depth of field there is in the shot. Same thing happens if you reverse or invert the lenses.

Its actually an update in technology from this. They use a circular polarizing system. One goes counterclockwise, the other clockwise. This way, you can see it in 3d at any tilt or angle :thumbup::thumbup:. How do I know this? My physics prof took the glasses home and took it to the head optics guy at my university. He let us know the secret :)

ahhh...
that's exactly what trippin's 'bout.
as for old 3-d system, ever notice that after an extended period of use,
and upon removal of filter that each eye would now see the reverse color of the opposing filter.
you can see this effect better by covering one eye and then looking on to a white sheet of paper or something, before moving on to the other eye.
