IN CITIES, ONLY A SMALL PORTION OF THE DAY’S NATURAL LIGHT actually makes it all the way to the street unbroken. You can almost think about it like rain, in that it drips, slithers, drains, and channels its way downward through a dense maze of structures and barriers. Along the way, that light is bisected, sliced, stenciled and tattooed by the surfaces it interacts with, stretching shadow patterns, glinting, ricocheting, stretching.
Glass, especially, constantly reshapes light, filtering it into delicate lattice-works and spectral spiderwebs, sifting it through windows, transoms, doors, windshields, storefronts. It reveals and conceals, crawling across buildings like an ever-changing sundial of shapes and schemes. Photographing the same hunk of glass on the hour can be like visiting a dozen different worlds, spread out like fanned playing cards over the course of a single day.
Light illuminates, making it a force that acts upon other objects, but it is almost more marvelous when it, itself, is acted upon, creating an endless choreography and echo of its colors and contours. It’s part of the great interactive ballet of cities, this push and pull between light and darkness. Sometimes you get a nearly kaleidoscopic effect from something very simple, like the etched glass in the revolving door seen above, which stamped a different snowflake of shapes onto the pavement at every turn and swivel.
If you’re given to experiment (or daydreaming), your own tabletop can become a tremendously valuable laboratory on the effect of light. Just grab the simplest object handy, be it an apple or a book, and arc a source of light from one side of it to the other. Imagine yourself a self-propelled sun and watch how easily you can create change in your private solar system. The actual design of such an exercise isn’t crucial, but making yourself mentally slow down, becoming aware of the tiny effects perpetually swimming about you, is invaluable. Photographs rise at the hands of some pretty small phenomena. Magnifying your gaze puts more images within your reach.
