Mesa Arch Sunrise
This is the classic Mesa Arch photo in Canyonlands NP in Utah. I made it with 5 exposures going from -4 to +4 and combined them in Photomatrix. The aperture was 18 to allow the sun's rays to be sharp in the image. I did a little sharpening in Photoshop, but did not enhance the saturation. The sun reflects off of the lower part of the arch and causes the underside of the upper arch to glow.
