Why Bad 3D, Not 3D Glasses, Gives You Headaches
Barence writes "The most common complaint about 3D is that the glasses give you a headache, but that's not actually true, according to the man who teaches the pros how to make better 3D. Speaking at the BBC in London, Buzz Hays, chief instructor for the Sony 3D Technology Center in Culver City, California, explained: 'It's not the technology's fault, it's really the content that can cause these problems. It's easy to make 3D but it's hard to make it good — and by "good" I mean taking care to make sure that this isn't going to cause eyestrain.' He went on to detail some of the mistakes made by inexperienced 3D film makers, from poor composition of shots, through uncomfortable convergence settings, to overuse of on-set monitors without viewing their content on a big screen. But the biggest admission Buzz made was that not even the 'experts' know all the tricks yet, which is why 3D should only get better from here. In the same seminar, Buzz also explained why 3D glasses are here to stay — at least for the next few years."
At least, I'm pretty sure that the movie Avatar was not physically squeezing on the sides of my head and pushing down on my nose.

Why do I hate 3D glasses? Because I'm near sighted and had to wear glasses every day of my life... now watching movies or television is going to require a SECOND pair on top of the first one? Go to hell, hollywood, for making my everyday life even more impractical than it already is.
I'd take a black and white movie/show with a decent story over Avatar and its ilk and damn day of the week.
What doesn't kill you only delays the inevitable
I'm sorry, I have yet to see a movie in 3D where 3D provided anything additional to my movie experience other than a headache.
I watched Avater, and was distracted from the movie by the places that the 3D effect broke up badly. Of course, I get distracted by the film reel change indicators also.
Why do the movie companies believe that we want 3D? Heck, why do the television manufacturers believe that I'm willing to spend 2 grand more for it? Does anyone here feel that its a useful addition to a movie? /frank
And the worms ate into his brain.
Call me back when they fix the depth of field issue. The whole scene needs to be in focus so that when my eyes aren't looking at precisely what the director wants, my eyes don't try to focus on something that can't be focused on.
Then Ebert is really against 3D because of how much darker the picture is, when normal movies are already projected too darkly half the time.
At this point, it still seems to be a gimmick. I remember reading that 3D ticket sales had fallen from 85% (or so) of ticket sales in some of the earlier 3D movies this year to ~40%. Clearly, people are realizing that it's usually a scam for an extra $5 from you.
Cameron worked on it for 10+ years. Nolan explicitly fought against making Inception 3D because he didn't think it would work. There is no way the no-name director of American Pie 7: Bagpipe Retreat is going to do 3D well.
Comment forecast: Bits of genius surrounded by a sea of mediocrity.
He's the chief instructor for the Sony 3D Technology Center, so of course he'll tell you its not the tech's fault. Its his job to make sure people don't go against this technology. Its all about PR and the millions/billions of dollars invested and wanted to be made from this. Its like when a cellphone loses signal when you hold it in the wrong way, its not their products fault, it's the users fault because to admit "Hey, we screwed up" will cost much more money then to try to trivialize the problem and hope people will shift blame from the real issue (the tech itself).
Attention... all grammer nazi"s! Is they're anything; wrong with: my post,
The 3D technology will only proliferate when the porn industry adopts it.
I just hope that it dies before it starts to change the way cinematographers shoot movies, because they are under pressure to make the movie '3d-able'. Composing a film for 3d is an entirely different paradigm compared to the decades/centuries of NORMAL filmmaking and cinematography. I bet in future decades, when people watch today's movies without the lame 3D glasses, everyone looks back at pictures from this era and wonder why everything is composed in the center of the frame, with deep-focus effects and limited pans and zooms.
Mirrors. Completely flat. Such good 3d that people have been known to walk into them by accident.
Please, that's not remotely true.
Watch Avatar. Now try to focus on something that's out-of-focus in the background.
"WTF", your eyes say, "I know I'm *supposed* to be able to bring that tree into focus, but I can't!" That's because it's *not* 3D. At best, its a fragile optical illusion.
Exactly. That's why I hate 3d movies, before I get the possible headache.
With 3d movies, since the screen is still flat, only one item can be in focus at any given time. The items in focus are those in the plane where the action is typically taking place, but sometimes something interesting is happening in the background. Attempts to view the background have you focusing on something that will never come into focus. This causes eyestrain and an uncomfortable visual feeling.
Most of the time people want to see what the director wants them to see; however, there were several scenes in Avatar where I wanted to look at the squad tactics in the background. It was quite disconcerting to know that they were permanently rendered out of focus.
If there wasn't part of the screen being rendered with tricks to simulate depth, I doubt I would have been so put off by the other parts of the screen failing to simulate depth in the same way.
