I used a single ordinary video camera but I edited the video for three-dimentional viewing - as far as I could search YouTube, this is the first 3D real world video done with a single simple camera. The 3D effect is produced using the cross-eye technique. Basicly, you should cross your eyes so as to see a third full image in the middle and then focus on that third image. Make sure both the screen and your eyes are horizontal and the screen is straight in front of you. If you are not familiar, you may need a few minutes of training. Then it will be as natural as normal vision. For more technical details and information search the internet for \"cross eye\" or \"cross eyed\" 3D viewing method.
WARNING: The current optometrist view is that cross-eyed viewing does not harm the eyes; it is rather a good exercise for the eye muscles. But it may cause fatigue and strain, even when you have mastered the technique. Please view responsibly.
