This is the magnificent Pont du Gard aqueduct in Southern France. It is a short segment of the 50 km aqueduct which carried water from Uzes to Nimes. This engineering marvel was built by 1st century Romans and is listed as a UNESCO heritage site. It is the second highest Roman structure built, only bested by about 3 meters by the Roman Colosseum. It also contains the largest arch span ever built by the Romans, about 80 ft. I find the most amazing aspect of the structure is that it was built with no mortar! Held together only by friction, it has weathered storms and floods for 2000 years.
This shot is composed of three bracketed images at 2-stop intervals. I processed HDR with Photomatix, and touched up with Aperture. I really like this image for a few reasons, one is simply the majesty of the subject. In addition, I have recently been working with HDR and am impressed with the outcome of this shot, and lastly, I have been focusing on taking images that incorporate water, either flowing or with reflections.
