Pulfrich effect is awesome.
Using it one can take 3D videos with a simple vidcam, without glasses, gadgets, etc.
That is as simple as to be risen to a vehicle that have windows toward the lateral, to aim the camera toward the side while this circulates slowly, and to press the shutter.
The optimum velocity, for a standard camera of 30 frames per second, is about 7,5 Km/h (4,66 Mi/h), but this is very elastic, I have verified that even to velocities over 30 Km/h (18 - 19 Mi/h) the effect is produced.
Step 1: Viewing 3D Pulfrich Effect
Once obtained the video, to appreciate it is as easy as the previous thing. A sun glass is taken, not very clear neither too dark, and it is put in front to the eye pertaining to the window by the one that the camera was aimed.
I will clarify this point, that is very important: A LENS of a sun glass is taken, not the pair. If the video was obtained aiming at the right, the dark lens is put in front of the right eye. If the video was obtained aiming at the left, the dark lens is put in front of the left eye. THE OTHER EYE SHOULD REMAIN OPEN, TOO.
That is all, folks.
Is not incredible?
Me I will not offend if some of you think that I am doing you a joke, or telling a lie. Test it and you will verify it for yourself. It is easy and cheap.
So that you can see that I am not a lier, last night I uploaded to YouTube two videos taken during the holidays with that technique. 'DO'NT LOOK THEM IF YOU THINK I AM DOING THIS TO OBTAIN VISITS TO YOUTUBE', that does not worry me it more minimum.
The videos link are RIGHT EYE and LEFT EYE
