FIGURE 2-1 Missouri Mountain, Mt. Belford, Mt. Oxford and Mt. Harvard from the summit of 14,196-foot Mt. Yale at sunset in January, Collegiate Peaks Wilderness, Colorado. I knew that a simple telephoto shot of the distant peaks would lack a sense of depth, so I searched the summit of Mt. Yale for an interesting patch of wind-sculpted snow that would be illuminated by light from the setting sun. If the snow patch had been entirely in the shade at the moment of sunset, the entire patch would have been nearly the same shade of blue and its form would not have been revealed clearly. The reverse-S shape of the most prominent snow ridge leads the viewer’s eye into the frame and creates a sense of depth.
