If the screen (zero parallax) is located about 13 feet in front of the camera in this shot (http://youtu.be/dLyBiK5XRjM), and about 40 feet in front of the camera in this shot (http://youtu.be/noNc4cRvuKY), then where is it located in this very hyper shot?

Horizontally post-panned stereoscopic 3D shot of the Hollywood sign and surrounding area.
Shot with Google Earth.
Very wide, unknown stereo base (interaxial).
A bit less than 1/30 net deviation (for a cubic illusion with any hFOV – from any seat in the house or theater).
.5% (1/2 of 1%) of positive parallax (beyond the screen disparity) for zero eye divergence on screens up to 40 feet wide (40 ft * .5% = 2.4 inches).
Ghost-free (on my 3D TV) pale gray-yellow solid border, skewed for your viewing pleasure. :)

Notice in this video that my new homemade Bloggie microphone windscreen doesn’t seem to muffle the sound, which is good, since I can just leave it attached to the camera.
What is that sound in the background, though? The refrigerator? My computer?

Getting only one or two video views is no longer fun for me (Jim and/or Janice?). I don’t see any way around this problem other than to shoot half nude women at the mall and chicks in bikinis at the beach. If teenage girls, Orange County housewives, Los Angeles ladies, Hollywood hopefuls, beautiful babes, young, old and everything in between, can’t generate enough video views to keep my interest going, then it’s pretty much over for me.
This is also a good thing for Janice, since she will save lots of money if I don’t have to go look for another more expensive hobby like most men have.
Thank God it doesn’t take much to make me happy.

In this Pasadena Steadicam Competition, anyone who takes longer than 1 hour to edit their entry will be disqualified.
I was using my $20 Steadicam made from pipes and a 2.5 lb weight, and Jim Carbonetti was using his professional, extremely expensive Steadicam that he uses to shoot Hollywood movies and chicks in bikinis at the beaches in southern California.
I also used my 1/30 Net Stereoscopic Deviation gag in this quick and dirty composition, where one shot defines the near point, another shot defines the far point,
and the other two are just anything goes, run and gun shots, all combined to produce a consistent, perfectly cubic illusion with close to 1/30 (3.33%) “NetD”.
Zeroing in on my target audience, this video was created specifically for Janice Maddy at work, so she can check the quality of her Dubois anaglyph viewing method
in the YouTube stereoscopic 3D media player.

The thing that amazes me when reading the online “professional” forums, like the CML-3D list, is some of those guys have state-of-the-art, pro stereoscopic gear and still can’t figure out how to shoot a decent 3D image. Going to a recent “Hollywood” 3D movie will prove my point.
This is why I always tell people that they are better off choosing four configurations that work every time, rather than getting confused over all the “possible” choices. I’d rather see a movie shot with four settings that result in great 3D than a movie that uses a wide variety of settings that only work “by chance” (“Accidental 3D”).
The next thing I think I’m going to do is take my 3D camera and start on the “tight” end, and no, I’m not talking about football, boys and girls…
Based on simple, elementary stereoscopic calculations, if I shoot a scene with a farthest visible point 3 feet away, I should place the camera close to 17 inches away from the nearest visible point. I’m going to start with a test shot, and see if there are any weird things that happen when I do this, e.g. making sure I don’t get limited depth of field or excessive non-stereo overlap that has to be cropped to set the stereo window, resulting in a reduced amount of net deviation. As long as I end up with 2.8% to 3.8% NetD in the final image, I won’t complain, but the closer to 3.3% I get, the happier I will be.

I could write a book about this, but let’s start with a short blog post. LOL.
3D in “Hollywood” (whatever the Hell “Hollywood” is supposed to be… I think the masturbating porn-worshipers have claimed most of it… maybe we should rename it “Hollywood Hell”… LOL) is typically shot below the optimum (Holy) amount of stereoscopic net deviation of 3.33% (1/30). You will see movies with everything from 0 (totally flat) to 2.5%.
This has catastrophic results, e.g. it “kills” 3D by making it too flat and unexciting.
3D in “Hollywood” also gives Roger Ebert a headache, but that is for another reason, i.e. variable amounts of Net Deviation combined with occasional excessive Negative Screen Parallax. But, I digress…… LOL.
The bottom line, here, is people have “drank the Koo-laid” (which was actually Flavor Aid) and have joined the wrong 3D Society. They joined the “Flat Earth 3D Society”, which typically has 2.5% Net Deviation or LESS.
There are a number of people we could blame this on, but I’m not a huge fan of name-calling. Just stick with the issues, Christian Soldiers…………
Before it is too late, and Jesus removes some of us from this Round Earth, people better join the Good 3D Society that knows how and why the Earth is perfectly round… not totally flat and not BORING flat (2.5% is BORING flat).

Have a Great Day. :)
