'''High-dynamic-range rendering''' ('''HDRR''' or '''HDR rendering'''), also known as '''high-dynamic-range lighting''', is the [[Rendering (computer graphics)|rendering]] of [[computer graphics]] scenes by using [[lighting]] calculations done in [[high dynamic range]] (HDR). This allows preservation of details that may be lost due to limiting contrast ratios. [[Video game]]s and [[Computer animation|computer-generated movies and special effects]] benefit from this as it creates more realistic scenes than with the more simplistic lighting models used.

Graphics processor company [[Nvidia]] summarizes the motivation for HDR in three points: bright things can be really bright, dark things can be really dark, and details can be seen in both.<ref name="6800_Leagues_HDR">{{cite web | url= http://download.nvidia.com/developer/presentations/2004/6800_Leagues/6800_Leagues_HDR.pdf | title= High Dynamic Range Rendering (on the GeForce 6800) | author= Simon Green and Cem Cebenoyan | format= PDF | year= 2004 | publisher= nVidia | work= [[GeForce 6]] Series | page= 3 }}</ref>
