THE FLEXIBLE FREEZE
By MICHAEL PERKINS
PHOTOGRAPHERS ACROSS THE LAST TWO CENTURIES HAVE CAPITALIZED ON ONE OF THEIR MEDIUM’S BEST TRICKS, the ability to freeze time, the sensation of carving out micro-seconds of reality and preserving them, like ancient scarabs trapped in amber. The thing known as “now”, with the aid of the camera, became something called “forever”, as things which were, by nature, fleeting were granted a kind of immortality. Events became exhibits, things to be studied or re-lived at our whim.
And yet, even as we extract these frozen moments, we mess around the edge of the illusion a bit, making still pictures also convey a sense of motion. Focus is a prime example of this retro-fitting of technique. No sooner had photography evolved the technical means to render sharp images than shooters began to put a little soft imprecision back into their pictures, by a variety of means: slow shutter speeds, time exposures, manual shaking, delayed flashes, and selective focus. Of all these techniques, at least for me, selective focus has proven to be the hardest to master.
Changing the messaging of a photographic story by using focus to isolate some elements and downplay others has always called for real practical knowledge of the workings of lenses and how they create focus as an effect. Recently, digital manipulation has allowed shooters to re-order the focal priorities of a shot after it’s taken, and in just the past few years, commercially available specialty lenses have allowed photographers to pre-select where and when focus will occur in an image, using it as interpretively as color or exposure.
I like to use the Lensbaby family of variable-focus lenses for what I call “flexible freeze” situations, times when focus can be massaged to create the illusion of speed. In the above shot, taken in a high-volume cafe, the small center of tight focus fans out to a near streaky quality at the outer edges of the picture. No one person is rendered sharp enough for features to register, or matter. What’s important here is the sensation of a busy lunch rush, which actually would be diminished if everything was in uniform focus.
Sharpness is certainly desirable in most cases for a strict re-creation of literal reality, but photography has never merely been a recording process. Focus can produce useful abstractions or atmospheres in a shot, so long as the effect serves the story. If it doesn’t help the image speak better, even a flexible freeze can quickly become a tiresome gimmick. Matching tools to goals is what good photography does best.
