IN 2008 the director Christopher Nolan’s “Dark Knight,” the second in his trilogy of Batman movies, introduced some audiences to a character not before seen in the franchise, or any studio narrative feature until that time. But that character wasn’t on the screen. It was the screen.
That would be Imax, a vast screen that can be as tall as an eight-story building. Though the name is popularly used to refer to screens, it is primarily a format involving special cameras and large-scale film, and before “Dark Knight” it had been known best for short documentaries about ocean life and space travel. Mr. Nolan shot parts of “The Dark Knight” using Imax cameras, with 30 minutes of such footage making it into the final film. When those images were seen in an Imax theater, they filled the screen from top to bottom with a giant, high-resolution image. Read the entire article on the New York Times website.
