OneLens revisits the Great Wall of China. Original postings in July/August 2012 used all iPhoto color correction. Slowly bringing pictures into Photoshop and seeing if I can get some better definition-especially in the neutrals and highlights. Visited the Mutianyu section of the Great Wall with smog so thick it was hard to see three or four watchtowers ahead. Visited July 20th, 2012. All pictures taken on my Canon T3i, with the kit 18-55mm lens.
