A sword-wielding angel protects Brussels from his perch far above the city's old fish market, as wings of another kind leave disintegrating contrails in the evening sky. Because the angel was mounted on a very high column, I used a medium telephoto focal length of 160mm in order to make the size of the sculpture equal one third the length of the jet contrail behind it. If the statue were any larger in the frame, the contrail would be cramped for space. On the other hand, if the angel were any smaller, the contrail would overwhelm it. That’s why I recommend telephoto zooms over fixed telephoto lenses. We can easily fine-tune the scale of our subject to make it work best with the size of its context. The scale relationship between statue and contrail also determines the size of the triangle created between the flow of the wing, the leg, and the contrail. This triangle defines the incongruous relationship between the mythical wings of an angel and the wings of jet aircraft that etch the sky with their contrails. I also tilted the frame to run the contrail dynamically from corner to corner, energizing the angel in relationship to the thrust of the gradually disintegrating contrail behind it.
