3D BASICS: FUSION DETERIORATION When a recording is made in 3D with the background at a distance and an object in the near foreground simultaneously, the human eye will perceive only the object in the foreground in 3D and not the background scenery. This is because as the distance between the subject in the foreground and background increases, binocular parallax widens significantly. TIPS: 1) Guidelines for background percentage gaps of two images:  Hollywood production concerns recommend a display ratio of less than 1.7%.  Japanese production concerns recommend a display ratio of less than 2.0%. 2) Binocular parallax for pop-up or background effects should be maintained at a maximum between 50 - 60mm to prevent eye fatigue and other adverse effects when viewing 3D video content. 3 meters from the camera to the object. 30 meters from the object to the background = 600mm binocular parallax. In this case, the human eye will not perceive background scenery in 3D. 600mm parallax! The object will be viewed on the screen surface. θ=-11° Recording on a stereo rig with 60mm binocular parallax. The human eye cannot perceive images in 3D when the divergence angle exceeds two degrees.
