Since the days of the first photographs, artists have used various techniques to extend the range of lights and darks in their photos. Photographic masters such as Ansel Adams and Edward Weston spent countless hours burning and dodging their prints to create images with extended dynamic range.

With the advent of digital photography, new horizons in extending dynamic range are possible. HDR techniques now make it easy to extend the dynamic range of an image well beyond the capability of the human eye.
