Why has this technique made audience members queasy?
When you watch a film, explains Adrian Bejan, a professor of mechanical engineering at Duke University, your eye combines "long and fast horizontal sweeps with short and slower vertical movements to process the picture." But this faster camera speed "requires the eye to sweep up and down faster than usual in close-ups to absorb unparalleled detail on a big screen," causing a significant amount of cognitive and eye strain. This technique "works for the big snowy mountains, but in close-ups the picture strobes," said one moviegoer. "I left loving the movie but feeling sick." Another audience member was more blunt: "My eyes cannot take everything in, it's dizzying," he said. "Now I have a migraine."
