Extensive researchers efforts have played a key role in enabling high dynamic range (HDR) imaging to be used in several consumer electronics products. Some of these consumer electronics include cameras, mobile phones, and the latest version of the iPhone. The HDR technology has been integrated in these devices to provide better lighting experience. HDR imaging has been used for research purposes for a long period of time and has become practice in many of the devices as new digital cameras and specialized software have been developed to speed and facilitate processes. HDR imaging involves a series of photographs of a luminous scene from the same viewpoint, ranging from fully underexposed to fully over-exposed images that are processed by software to produce luminance maps. There are several systems to produce luminance maps using HDR photography, including the Photolux system using the Nikon Coolpix 5400 camera and a fisheye lens.
