My free monthly wallpaper for July is a shot of sunrise at Machu Picchu in Peru. Click on either image to open a full resolution version.
About the image: This photo was shot on my Canon 40D with my 10-22mm lens at 11mm. I exposed the sensor for 1/60th of a second at f/11 with an ISO of 400. I then imported the photo into Lightroom where I used selective adjustments to compress this high-contrast scene.
