Tune up your banjo, baby.
This stereoscopic 3D movie clip has .5% (1/2 of 1%) positive parallax (left/right eye disparity beyond the screen), which introduces zero eye divergence on any screen size up to about 40 feet wide (40 ft * .5% = 2.4 inches).
The near point is a little more than 3 feet away from the camera, and the far point is about 15 miles away.
The stereo base (interaxial) is a bit less than 1 inch of separation.
The stereoscopic net deviation (NetD) is close to 3%, which creates a cubic illusion (2.8% to 3.8%, with zero Z-axis stretch or compression) with any horizontal field of view (hFOV), i.e., when viewed from any seat in the house or theater on any size screen.
Zero parallax (apparent depth at the screen) is about 13 feet away from the camera.
Shot with a Sony Bloggie 3D camera.
I don’t normally make videos in the evening, but wanted to show off my brand new sheet of clear plexiglass or acrylic or whatever it’s called, while Janice Maddy plays “Never Mind” in the background and does her evening feet exercises. I bet I’ve spent 100 dollars at the Dollar store for junk that doesn’t work. Job security for the garbage man, I guess.
The piece of “glass” should work great for stereoscopic 3D Designated Near Point gags. No, I didn’t buy the “glass” at the Dollar store. :/
Shoot these four configurations, easily estimated “by eye” without a stereoscopic calculation. I’m hoping Janice makes up a “cheerleader cheer” for this and I can film it, e.g. “Three feet, six feet, fifteen feet, infinity”… based on a “typical” adult male arm length or something close to it, with the camera placed approx at the shoulder. Camera in 16:9 mode (4:3 mode, e.g. “webcam” mode would require a small adjustment to this estimate):
1) Distance to near point from the camera = arm extended, palm flat against near point, minus approx 5 inches.
Far point = approx 3 feet.
2) Distance to near point from camera = arm extended, palm flat against near point.
Far point = approx 6 feet.
3) Distance to near point from camera = arm extended, finger(s) pointed straight ahead, touching near point.
Far point = approx 15 feet.
4) Distance to near point from camera = arm extended, finger(s) pointed straight ahead, touching near point, plus approx 5 inches.
Far point = approx “infinity”.
