High-dynamic-range rendering (HDRR) is the real-time rendering and display of virtual environments using a dynamic range of 65,535:1 or higher (used in computer, gaming, and entertainment technology). [6] HDRR does not require a HDR display and originally used tone mapping to display the rendering on a standard dynamic range display.
Another aspect of HDR rendering is the addition of perceptual cues which increase apparent brightness. HDR rendering also affects how light is preserved in optical phenomena such as reflections and refractions, as well as transparent materials such as glass. In LDR rendering, very bright light sources in a scene (such as the sun) are capped at 1.0.
Current generation gaming systems are able to render 3D graphics using floating-point frame buffers, in order to produce HDR images. To produce the bloom effect, the linear HDRR image in the frame buffer is convolved with a convolution kernel in a post-processing step, before converting to RGB space. The convolution step usually requires the ...
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 is supported by a wide variety of companies, which include monitor and TV manufacturers such as Dell, LG, Samsung, Sharp, VU, Sony, and Vizio, [8] [9] as well as Sony Interactive Entertainment, Microsoft and Apple which support HDR10 on their PlayStation 4, Xbox One video game console and Apple TV platforms, respectively.

Tone mapped high-dynamic-range (HDR) image of St. Kentigerns Roman Catholic Church in Blackpool, Lancashire, England, UK. Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images in a medium that has a more limited dynamic range.
