The Windows District of Arches National Park is a fairy world of rock. The park, as a whole, contains the largest concentration of rock arches in the world, and those of the Windows District are as incredible as any to be found. In exploring various angles and perspectives recently we came upon an opening in the massive Entrada Sandstone formations which may at one time been an arch itself, but is now a long, rounded outcrop, open to the sky and offering an amazing view northwest toward the Garden of Eden and Balanced Rock tiny in the distance. As we watched the light slowly fade, it began to highlight the various formations in intense tones of warmth, but at the same time it cast a rim light across the top of the outcrop at our feet. Using just the edge of the rock, where the highlight ran, as a floor, I framed the right edge of the image with the edge of the Entrada formation and placed the highlighted formations in the mid-ground so that the lighted tops were near to the right vertical third line. The dark gray clouds overhead were an interesting contrast to the still-whitish cumuli on the far horizon. A focal length of 20mm gave me the angle-of-view I wanted. An aperture of f/22 provided depth-of-field;and a shutter speed of 1/10th second at ISO 100 gave me an overall somewhat-darker-than-medium eposure. Fairyland at sunset is magic.
