A MATTER OF DEGREE
By MICHAEL PERKINS
NIGHT CREATES SUCH A DRASTICALLY DIFFERENT FLAVOR in anyone’s photography that some shooters, romantically attracted to its unique look, have made night-time their exclusive domain. Night is also the toughest time of day to render properly, and a zone wherein one’s interpretation of “reality” varies wildly. From the earliest days of the photographic medium, the hours after sunset were, first and foremost, a technical minefield, filled with pitfalls and perils.
Today, fast lenses and the higher ISO that can be dialed up pretty much at will mean fewer tripod shots, more hand-held shots, and thus a much bigger yield of often stunning night-time images. Even modest cameras are evolving so quickly that it’s getting hard to remember a time when we couldn’t shoot pretty much whatever we desired.
In many night settings, the contrast between bright and dark objects is dramatically multiplied. That means that getting proper exposure still has to be calculated based on widely varying elements within the frame. The night I took this image at New York’s Lincoln Center, I shot the various performance buildings on the “campus” in every compositional combination and setting possible, using a Nikon f/2.8 24mm prime lens. I framed the theatres at right angles to each other, by themselves, juxtaposed with neighboring skyscrapers, with and without the center’s fountain plaza, from medium distances to the lobby, tight distances to the lobby, and so on. In one “almost” calculation, I shot at f/8 and about 1/80 sec. at 1500 ISO, didn’t like how grungy it looked, then cranked the lens wide open to f/2.8, used as slow an exposure as I could execute hand-held (about 1/20 sec.), and backed off the ISO to about 400. That’s the combo you see above.
Normally, an aperture like f/2.8 produces a very shallow depth of field, which is generally bad for distant subjects. However, if you are focused to infinity, and your subject is, say, forty feet away, the image starts to get a little sharper at about twenty feet out, and is pretty sharp by forty. One sharpness caveat: if you use a slow exposure, as I chose to, and you’re also boosting your ISO, the electrical lights in your image will begin to go soft and globby fairly quickly…to “burn in” to some degree. You can see this in my image in the lobby chandelier, which registers as a velvety glow instead of a sharp grouping of individual bulbs. As an alternative, if you have time to experiment, you can amp up the up the ISO a little more, speed up your shutter, and perhaps render the lights a little sharper. This depends greatly on how many wives you have standing nearby, asking, “can we please just walk to the subway now?” It’s also not the only solution possible. Fiddle with it and see what works for you.
Also, if you are lucky enough to be shooting on a tripod, then you can shoot at minimal ISO, an aperture of f/11 or narrower, and as long an exposure as you desire. But the above guidelines are offered for someone shooting hand-held, and in a moderate hurry. I use very fast prime lenses to give me the sharpest focus and the most light latitude possible in the greatest number of situations, assuming that I won’t be allowed to mount a pod, even if I wanted to take one to the theatre (I don’t). So, as always, you have to decide a little ahead of time what you might be shooting, what the reality on the ground will be, and what you’ll need in the way of toys to bring home a goodie. Night is a very different animal, but trying to tame it is surprising and fun.
