High dynamic range (HDR)

A range of luminance values (levels of brightness) in an image that exceeds the luminance values of traditional, or standard-dynamic-range (SDR), images. For example, the HDR PQ standard can represent luminance values as high as 10,000 nits (candelas per square meter) with a dynamic range of 14 stops or more, creating more realistic color transitions and revealing more detail in both shadows and highlights.
