Time, Photographed

“What makes photography a strange invention is that its primary raw materials are light and time.”

JOhn Berger

Photography is often understood as the capture of an instant. Yet time, like light, can also become an active part of the image.

For this essay, I think of creative long exposure not as a particular shutter speed, but as a relationship between shutter speed, movement, and perception. It begins when the length of an exposure renders the world differently from the way we ordinarily see it. Depending on the subject, that transformation may begin in a fraction of a second or extend over many minutes.

These photographs explore what happens when time accumulates within the frame: lights trace paths through space, water changes form, crowds dissolve into traces, and familiar places take on a different sense of stillness.

Creative long exposure, then, is less a technical category than a way of seeing time.

Same viewpoint. Same exposure. Same duration. The low evening light made a 34-second exposure possible without filtration, with the camera supported on a compact travel tripod. In the first, the Ferris wheel was nearly stationary and the passage of time is barely visible, with its structure and individual lights remaining distinct. In the second, the wheel turned throughout the full 34 seconds, tracing circular light trails that could not be seen with the unaided eye.

The distinction is central to my approach to creative long exposure: not simply duration dictated by low light, but the deliberate interaction of time, movement, and perception.

Architecture is often photographed as something fixed and permanent. But in locations such as the Montréal Métro, the structure is experienced through a constant flow of movement. Here, in-camera image stabilization let me work handheld at slow shutter speeds, allowing the train to become a trace of passage. Changing the length of the exposure changes how that movement is rendered, from a recognizable train toward abstraction. This fresh perspective reveals the built environment through its function, not simply its form.

The natural world offers a different relationship between movement and form. Here, a neutral density (ND) filter reduced the light reaching the camera, allowing exposures much longer than the conditions would otherwise permit. For exposures this long, I used a tripod to keep the camera fixed while movement accumulated in the frame.

In the first image, a 24-second exposure on a cloudy day softens water, sky and horizon. In the second, a 68-second exposure smooths the lake beneath a clear sky, reducing the scene to almost geometric fields of colour. Very different images of the same body of water, but in both cases creative long exposure simplifies detail, shifting the familiar landscape toward abstraction.

In the Lake Ontario images, movement simplifies the landscape by removing transient detail. The same principle can be applied more selectively. Here, I chose an exposure of about two seconds: long enough to smooth the flowing river, but short enough for the heron to remain sharp. The moving water becomes a simplified background, while the contrast between movement and stillness provides subject isolation. The result is less a conventional wildlife photograph than an environmental portrait.

Taken to a further extreme, minutes-long exposures can blur, ghost or even erase people who occupy the frame for only part of the exposure. At 1/160 second, museum visitors crowd the frame and compete visually with the iconic statue of Nike, the Greek goddess of victory. Adding a 10-stop ND filter and reducing ISO from 3200 to 100 extended the exposure to 161 seconds, blurring much of the crowd. Stopping down from f/4 to f/5.6 doubled the exposure to 323 seconds, further diminishing the visitors and emphasizing the statue. The longer the exposure, the less strongly transient people register, shifting the image from presence toward absence.

Tripods are not permitted in the museum, so I found this viewpoint from the level above and made the long exposures with the camera resting on the floor. When a tripod is not practical or permitted, nearby surfaces and structures can provide improvised camera support.

At the Louvre, long exposure diminishes transient subjects. It can also do the opposite. For this London street scene, I chose a 30-second exposure not to remove the traffic, but to accumulate it. Passing vehicles become superimposed ghost images and light trails, competing for space within the frame and emphasizing the visual chaos of the city.

In the London image, movement accumulates to create visual complexity.  In Time, movement serves a different compositional purpose.  Using a tripod and a 10-stop ND filter, I extended this daytime exposure to 64 seconds, transforming passing clouds into streaks that contrast with the hard geometry of Kosso Eloul’s 1975 sculpture Time. Here, the relationship between movement and stillness becomes part of the composition itself.

Once shutter speed becomes a creative choice rather than simply a response to available light, time itself becomes a material for experimentation.

Long exposure can also move beyond representation into abstraction. Here, the rotation of a vinyl record transforms familiar details into concentric bands of colour and light. The same principle can be explored with almost anything that moves, using shutter speed not simply to record motion, but to reshape how a subject is seen.

Creative long exposure is ultimately less about slow shutter speeds than about choosing how much time a photograph contains. By considering the interaction of time, movement, and perception, the photographer can trace light, simplify form, isolate a subject, erase distraction, or create something entirely unexpected. Time becomes not simply something photography freezes, but something it can shape.
