The parallax in 3 D cinematography refers to the separation of the left and right images on the display screen. The Fig 1.5 shows the different screen parallax. In positive parallax, the objects appear behind the screen. The image is shifted to the left for the left eye and to the right for the right eye. In zero parallax, the objects appear at the screen plane. The left eye and right eye image are in the same position on the screen. In negative parallax, the objects appear in front of the screen. The image is shifted to the right for the left eye and to the left for the right eye.
