Another form of layering comes into play when the middle-ground subject is transparent. In this case, my subject is the glass-enclosed bridge that connects the original Denver Art Museum with its new wing. I used a screen of trees to create a semi-transparent foreground layer. The transparent bridge in the middle ground contains not only structural beams, but chairs and reflections as well. The darker background layer includes parts of the buildings that comprise Denver’s cultural center. The overall effect is magical – the bridge appears to be floating in space, an ethereal structure held together by the rhythms of its own geometry.
