At 8803′ Point Imperial on the North Rim is the highest overlook in Grand Canyon National Park, and since it faces primarily eastward there is no chance of a sunset opportunity, yet something almost as spectacular can sometimes be seen. Looking to the northeast, the desert stretches away for miles into the spectacular uplift of the Vermilion Cliffs, the second step of the “Grand Staircase;” and in the late-afternoon, when the light no longer touches the shaded lower reaches off the point, the rise of the first cliffs catches the waning glow and sets the rock on fire. In the contrast between the twilight valley and the radiant vermilion wall, the beauty of light reveals itself. I wanted to isolate a very small portion of the larger visual field in order to increase the drama of the light, and so I chose a focal length of 450mm. The lines of the foreground cliff and the low midground mesa added depth and visual paths into the image. The focal length reduced my depth-of-field, but the camera-to-subject distance and an aperture of f/22 gave apparent sharpness throughout. A shutter speed of 1/4th second at ISO 100 gave me a somewhat darker-than- medium exposure.
