Does anyone have the Hitchcock 3-D film on video? This would be the film that was used in the "Art of Making Movies" Universal Studios attraction.
In order for the video to look correct, however, the videographer would have to have used a polarizer on the front of his/her camera lens, or the plastic lens used in the 3-D viewing glasses (...don't laugh, I've tried this, and it works if the video camera's lens is small enough to be covered by the cut-out lens.)
Just to clearify, a polarizer (which is essentially what the 3-D glasses are) would cancel one of the 2 images projected onto the screen, thus creating the 3-D effect. Without this correction, the image would appear as a blur, or two sandwiched images upon closer inspection. Also, the polarizer would have to be adjusted properly in order to accomplish this. If not, the image would remain un-corrected. Try tilting your head to the side while watching a 3-D movie at a theme part, the 3-D image becomes the blurry 2-D image, exactly the same as if you were not wearing the glasses at all!f
Note: that's why polarizers for video/still cameras are round and often rotate-able. You have to be able to "turn" or "rotate" them slowly until the filter aligns itself correctly with incoming light. Just plopping one on your lens won't always accomplish its task.
Also, just for fun, while wearing the glasses, look at someone next to you who is also wearing the glasses. Now, close one of your eyes, that oppisite eye-side lens of the person accross from you will turn opaque, or black, while their other lens remains transparent. The opposite occurs if you close your other eye. Neat stuff.
I won't get in depth about how 3-D movies work, but these tips may help some of you who plan to record current 3-D attractions on video.
But back to the main point, anyone have the Hitch 3-D film (corrected or otherwise)?
Thanks,
