A NEW TAKE ON OPAQUE

THE TWENTIETH CENTURY’S REVOLUTION IN URBAN ARCHITECTURE produced a radical re-imagining of the physical science of erecting buildings, along with a remarkable shift in what those buildings should look like. An extreme shift in outward design can be tracked from the ornate Greco-Roman and Gothic textures of the Woolworth Building at century’s start to the stark, spare rectilinear boxes of the ’40’s and 50’s, as we jetted from doric columns, oak clusters and gargoyles to the completely un-ornamented glass boxes that we associate with, say, the Pan Am or United Nations buildings at the other end. That changed the way we live, and likewise transformed the way we photo-document our cities.

And, whatever your opinion of what came to be called the “International Style”, the boxes today co-exist with their more decorous ancestors, a contrasting mix which creates amazing opportunities for abstraction. The collision of the two periods creates an endless shuffling of visual cues, with all that glass and terra cotta dueling for dominance in our compositions. And therein lies a tip: one tool which you may find of enduring value in shooting in these situations is a circular polarizing filter, which can help you create a wide variety of effects…quickly, and on the cheap.

People in sun-soaked sectors of the world mostly use the CPL to deepen the blue in overly-bright skies, but the filter’s ability to cut glare on reflective surfaces like water and glass can also be dramatic, and that’s how I use it in urban settings. I’ve come to love the idea of a sheer wall of glass in one building being stamped with all the details of the building directly across the street (over my shoulder). Twisting the upper ring of the CPL dials in the degree of glare you want in your image, allowing you to see none, some, or all of your neighboring structure in the glass in front of you. One caution: the filter also deepens color and can rob you of up to a stop of light, so you want to plan your exposures more carefully, something that’s done easier shooting on full manual.

The dominant idea of design in the International Style was to eschew detail and ornament to as great a degree as possible. That resulted in a lot of very boring exteriors as a vast crop of largely faceless boxes shot off the assembly line. However, using their sheer screens of glass as a vibrant kind of video display for the neighborhoods around them actually breathes a little life into them, and the circular polarizing filter gives you a remarkable amount of control over that process.
