High dynamic range imaging
In computer graphics and cinematography, high dynamic range imaging (HDRI for short) is a set of techniques that allow a far greater dynamic range of exposures than normal digital imaging techniques. The intention is to accurately represent the wide range of intensity levels found in real scenes, ranging from direct sunlight to the deepest shadows.
Greg Ward (Larson) is widely considered to be the founder of the discipline of high dynamic range imaging. The use of high dynamic range imaging in computer graphics has been popularised by the work of OpenEXR
