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."
