The recent increase in 3D films has upset me over the past few years. As a kid 3D, was always used the same exact way in every movie. There would always be something popping out at you. The best genre 3D was being used for was horror movies. Even still today those types of scares are still widely used are a lot of the things that stand out in 3D cinema. Many people do not seem to care about the obvious fact that 3D takes the audience away from the movie. Walter Murch who is the editor for Apocalypse Now and The English Patient is neither a fan of 3D also.He says the 3D movies are one stop lower than it's 2D counterparts.That means that every part of the movie is darker, sometimes making it nearly impossible to pick out certain details He wrote a letter to Roger Ebert stating his opinion on 3D. He said that the biggest issue with the 3D scene is the focus and convergence issue. The way that 3D movies work is that it only shows you half of the screen at one time. They switch the focus from both sides of the screen one after the other. Your eyes converge in the middle of where you are focusing. When you are watching 3D your eyes have to converge on different points of the screen split seconds after each other. This is the reason why many people get headaches after just watching the movies for a mere twenty minutes. It is something that 60 million years of evolution is unwinding. This is a deep issue that is wrong with 3D. No matter how much the technology improves you can never make full 3D until you make a hologram.
