In this letter, Hollywood film editor Walter Murch explains why 3D in films can only ever be a gimmick.
....So 3D films require us to focus at one distance and converge at another. And 600 million years of evolution has never presented this problem before. All living things with eyes have always focussed and converged at the same point. ....This is a deep problem, which no amount of technical tweaking can fix. Nothing will fix it short of producing true "holographic" images.
I've seen two films in the past year which employ the latest 3D technology, and was unimpressed. But I assumed the technology just hadn't been mastered yet, because such acclaimed directors as Steven Spielberg and James Cameron had said they would film exclusively in 3D in the future. I trusted the professionals.
Apparently, the professionals are fools. Like all human beings, they are willful and sometimes let desires cloud their judgement.
Politicians aren't the only ones commonly proposing actions which fly in the face of reality. What are some examples from other industries?
