HDR

High dynamic range (HDR) is a dynamic range higher than what is considered to be standard dynamic range. The term is often used in discussing displays, photography and 3D rendering, including digital imaging.

HDR imaging is the compositing and tone-mapping of images to extend the dynamic range beyond the native capability of the capturing device.

On January 4, 2016, the Ultra-HD Alliance announced their certification requirements for HDR displays. To be certified as different types of HDR displays such as LCD and OLED, the HDR display must meet defined brightness, black level and contrast-ratio levels.
