I passed through the Red Canyon area of Utah driving to Bryce Canyon National Park. As with most of our Desert Southwest, the area is quite photogenic in the mornings and afternoons when the sun is at a low angle and somewhat flat and uninteresting at mid-day. I shot this image of a red sandstone formation with a single lonely tree growing on top late on a Fall afternoon. The blazing red color of the stone formation is quite natural and I have not enhanced the color in post processing. However the colors of the rock formation and the sky were made more vibrant using a CPL filter
I used a Canon 40D with 70-200mm f/4L IS lens at 200mm with a Hoya Multi-Coated CPL. I believe that a CPL is just about mandatory for desert Southwest photography and the changes of color and saturation are breathtaking as you rotate the polarizer. I also love using a long lens o isolate portions of the scene.
