As a measure of light emitted per unit area, this unit is frequently used to specify the brightness of a display device. The sRGB spec for monitors targets 80 cd/m 2 . [ 3 ] Typically, monitors calibrated for SDR broadcast or studio color grading should have a brightness of 100 cd/m 2 . [ 4 ]
Sunlight readable monitors typically provide at least 800 nits of brightness, [1] [non-primary source needed] versus 200–300 nits brightness for a typical desktop computer monitor. [2] Sunlight readable monitors may also be optically bonded.
HDR10 Media Profile, more commonly known as HDR10, is an open high-dynamic-range video (HDR) standard announced on August 27, 2015, by the Consumer Electronics Association. [1] It is the most widespread HDR format. [2] HDR10 is not backward compatible with SDR. It includes HDR static metadata but not dynamic metadata.

Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. [1] [2] [3] It covers content creation, distribution, and playback.[1] [4] [5] [6] It includes dynamic metadata that define the aspect ratio and adjust the picture based on a display's capabilities on a per-shot or even per-frame basis, optimizing the presentation.
HDR10+, also known as HDR10 Plus, was announced on 20 April 2017, by Samsung and Amazon Video. HDR10+ updates HDR10 by adding dynamic metadata that can be used to more accurately adjust brightness levels up to the full range of PQ code values (10,000 nits maximum brightness) on a scene-by-scene or frame-by-frame basis.
The highlights—the brightest parts of an image—can be brighter, more colorful, and more detailed. [2] The larger capacity for brightness can be used to increase the brightness of small areas without increasing the overall image's brightness, resulting in, for example, bright reflections from shiny objects, bright stars in a dark night scene, and bright and colorful light-emissive objects ...
The use of high-dynamic-range imaging (HDRI) in computer graphics was introduced by Greg Ward in 1985 with his open-source Radiance rendering and lighting simulation software which created the first file format to retain a high-dynamic-range image. HDRI languished for more than a decade, held back by limited computing power, storage, and ...
