ANYONE WHO REGULARLY PHOTOGRAPHS GLASS SURFACES realizes that the process is a kind of shot-to-shot negotiation, depending on how you want the material to react and shape your subject. There is really no absolute “look” for glass, as it has the ability to both aid and block the view of anything it’s around, in front of, or near. Viewed in different conditions and angles, it can speed the impact of an image, or foil it outright.

I love shooting in urban environments, where the use of glass has shifted dramatically in recent decades. Buildings that were 90% brick or masonry just fifty years ago might be predominantly wrapped in glass today, demonstrably tilting the ratios of available light and also changing what I call the “see-through” factor…the amount of atmosphere outside a building can be observed from inside it. This presents opportunities galore of not only what can be shown but also how abstracted glass’ treatment of reflection can serve a composition.

Against the advice of many an online pundit, I keep circular polarizing filters permanently attached to the front of all my lenses so that I can modify reflections and enhance color richness at my whim. These same pundits claim that leaving the filter attached when it’s not “needed” will cost you up to two stops of light and degrade the overall image quality. I reject both these arguments based on my own experience. The filters only produce a true polarizing effect if they are either at the right viewing angle vis-a-vis the overhead sun, or if they are rotated to maximize the filtering effect. If they don’t meet either of these conditions, the filters produce no change whatever.

Even assuming that the filter might be costing you some light, if you’ve been shooting completely on manual for any amount of time, you can quickly compute any adjustments you’ll need without seriously cramping your style. Get yourself a nice fast lens capable of opening to f/1.8 or wider and you can even avoid jacking up your ISO and taking on more image noise. Buy prime lenses (only one focal length), like a 35mm, and you’ll also get better sharpness than a variable focal length lens like an 18-55mm, which are optically more complex and thus generally less crisp.

In the above image, which is a view through a glass vestibule in lower Manhattan, I wanted to incorporate the reflections of buildings behind me, see from side-to-side in the lobby to highlight selected internal features, and see details of the structures across the street from the front of the box, with all color values registering at just about the same degree of strength. A polarizer does this like nothing else. You just rotate the filter until the blend of tones works.

Some pictures are “about” the subject matter, while others are “about” what light does to that subject, according to the photographer’s vision. Polarizers are cheap and effective ways to tell your camera how much light to allow on a particular surface, giving you final say over what version of “reality” you prefer. And that’s where the fun begins.




GLASS SURFACES REPRESENT A SERIES OF CHOICES FOR PHOTOGRAPHERS, an endless variety of effects based on the fact that they are both windows and mirrors, bouncing, amplifying or channeling light no less than any other subject in your frame. No two shooters approach the use (or avoidance) of glass as a compositional component in quite the same way. To some, it’s a barrier that they have to get past to present a clear view of their subject. To others, its fragments and shards of angle and light are part of the picture, adding their own commentary or irony.

I usually judge glass’ value in a photograph by two basic qualifiers: context and structure. First, context: suppose you are focused on something that lies just beyond a storefront window. What visual information is outside the scope of the viewer, say something over your shoulder or across the street, that might provide additional impact or context if reflected in the glass that is in direct view? It goes without saying that all reflections are not equal, so automatically factoring them into your photo may add dimension, or merely clutter things up.

The other qualifier is the structure of the glass itself. How does the glass break up, distort, or re-color light within an enclosure? In the above image, for example, I was fascinated by the complex patterns of glass in an auto showroom, especially in the way it reassigned hues once the sun began to set. I had a lot of golden light fighting for dominance with the darker colors of the lit surfaces within the building, making for a kind of cubist effect. No color was trustworthy or natural , and yet everything could be rendered “as is” and regarded by the eye as “real”. ┬áThe glass was part of the composition, in this instance, and at this precise moment. Midday or morning light would render a completely different effect, perhaps an unwelcome one.

Great artists from Eugene Atget to Robert Frank have created compelling images using glass as a kind character actor in their shots. It’s an easy way to deepen the impact of your shots. Let the shards and fragments act like tiles to assemble your own mosaics.
