Disney Research has found a way to preserve the awesome quality of high-dynamic range or HDR videos when they're shown on consumer-level TVs and displays. See, HDR videos can show shadows and light better than footage taken by conventional equipment can -- in fact, the setting's purpose is to record what we see rather than what the camera sees. Problem is, typical consumer TVs and screens these days aren't capable of displaying them, unless they go through a process called tone mapping.
Unfortunately, existing tonal mapping techniques downgrade HDR videos' quality, so that most of their details get "lost in translation," so to speak, or introduce unwanted effects like flickering and ghosting or after-image. Disney's new tonal mapping technique, however, prevents these things from happening. If you'd like to know the science behind the technique, make sure to pore over the team's research paper for more info. Or, you know, you can just watch the video below for a demonstration of what the technology can do.
