High Dynamic Range (Imaging) techniques allow a greater dynamic range of exposure (stops) than normally possible, with the intention of accurately representing the wide brightness range of real scenes ranging from direct sunlight to deep shadows. This is sometimes used with computer-generated images or photography (often by taking several pictures of a scene, each with a different exposure setting) and it can provide a large amount of headroom for the adjustment of images in post production.

HDR can have a significant effect on the viewer experience. Some consider it as the best achievable next step beyond the normal experience of HD – placing it above 4K and HFR.
