H igh dynamic range imaging is a technique that can help to overcome the limited tonal capacity inherent to film and sensors. It involves making a series of bracketed exposures and recombining the results in post capture processing. HDR image formats are scene-referred, in contrast to traditional images which are output device referred. This method produces images that have a "hyper-reality", carrying great detail throughout the tone scale. The goal is to accurately represent the wide range of light intensity levels found in real scenes, ranging from direct sunlight to deep shadows.
"Light glorifies everything. It transforms and ennobles the most commonplace and ordinary subjects. The object is nothing; light is everything."-Leonard Misonne
This is not a new method per-say, as it has been used by master painters for centuries. They recognized that our eyes determine contrast locally, so increasing the contrast at local edges increases the overall perceived contrast of the scene. What is new is the incorporation of this capability in consumer level digital imaging devices, including cameras and monitors.
