a combination of 3 or more images, at 3 or more exposures. This is usually done with one at normal exposure and one each, 1 or 2 stops above and below. These are combined in one of many softwares, I prefer Photomatix. This image was taken at about 1:00 with the sun high in the sky, which blew out the light places in the rock and ruins in the cave where completely dark. HDR brought out details in both and allowed for a photo that is closer to what I saw.
