This shot was taken when I was on a weekend trip with my wife. We went up to the Tonto Natural Bridge which is in Payson Arizona and as we were walking around the top of the bridge I saw this hole in the ground that looked all the way through the bridge to the water and rocks below.
 
Using my beautiful Sigma 18-35mm f/1.8 I got as close as I could and snapped 7 bracketed shots that I would later combine into an HDR composition. I first imported everything into Lightroom, exported the 7 images to PhotomatixPro, tweaked the HDR settings, imported that back into Lightroom and made my final edits. The end result really brought out the colors in the green moss and the colors in the sides of the rock.
