I build this Grand Canyon evening vista around four successive content layers. The foreground layer features the massive, rock-strewn bluff protruding into the canyon on my right. It provides dimensionality – depth perspective – to the scene. The middle layer is a transitional layer – shadowy buttes on the canyon floor, linking the foreground to the subject layer itself: the North Rim of the Grand Canyon, gilded by a very brief appearance of the setting sun through the evening overcast and haze. The fourth and final layer is the background layer -- the rolling hills that top the North Rim, and the evening sky, streaked with clouds, just overhead.
