Lasers. They're the future of cinema, so you better get used to it. I've been attending CinemaCon (formerly ShoWest), the movie theater owners' convention, for the last 9 years and have seen many fantastic technical demos. One year James Cameron came and showed us his first look at High Frame Rates; one year Dolby introduced their (now everywhere) Atmos sound system with a custom install in a big auditorium where we get to see screenings. This year, Dolby held a demo of their latest offering - a system called Dolby Vision (we've written about it recently). It runs on two 4K laser projectors and they claimed that the contrast ratio they were getting up to is 1,000,000:1. Most cinemas today are barely 2,000:1. It was mesmerizing to see.
