High Dynamic Range Rendering (HDRR) is a technique used in computer graphics and video game development to produce images and video with a higher dynamic range of brightness, contrast, and color than is possible with traditional rendering methods. This means that HDRR can represent a wider range of luminance values and more vivid and accurate colors, resulting in more lifelike and immersive images.
The increased dynamic range is achieved by using floating-point representations of color and brightness values, which allows for a much greater range of values than traditional 8-bit or 10-bit representations. HDRR images can be displayed on HDR-capable displays, which are able to reproduce the wider range of brightness and color values, resulting in a more vivid and lifelike image.
HDRR is becoming increasingly important as displays and consumer technology continue to evolve and improve, and it is becoming a standard feature in many high-end video games and other visual media.
