..an HDR image is commonly made by taking three or more photos of the same scene,each at different shutter speeds.The result is the bright , medium,and dark photo,based on the amount of the light that got through the lens . A software process then combine all the photos to bring the details to the shadow and highlight both . this helps to achieve same task on the final photo that the human eye can accomplish on the scene . To me the HDR process helps the photos look more....let's say....evocative !
