1886 Étienne-Jules Marey – Shaking a Flexible Rod

The First Chronophotographic Capture of Oscillatory Motion – Rendering Time Visible

In 1886, Étienne-Jules Marey produced one of the earliest chronophotographic visualisations of wave motion using a flexible rod. As he shook the rod with rhythmic precision, a camera captured its movement in a single exposure, creating a sinuous, ribbon-like trail that rendered invisible oscillations visible for the first time. This experiment formed part of Marey’s pioneering research into movement at the Collège de France and the Station Physiologique in Paris.

To visualise the full wave pattern, Marey employed a custom horizontal plate format designed specifically to extend the visible span of time. A fixed camera, dark backdrop, and minimal visual interference ensured that the motion itself became the subject.

Unlike earlier photographs that froze time, Marey’s method layered time within a single frame. By combining photography with mechanical precision, he developed a visual language for studying motion—one that would influence physiology, aerodynamics, and eventually film. This image marks a turning point where photography became a scientific tool, capable of measuring not only form, but force, frequency, and flow.

Available information: This image, part of Marey’s pioneering chronophotographic studies, captures the motion of a flexible rod as it vibrates in the scientist’s hand. Created in 1886, the photograph belongs to a series of experimental visualisations that transformed invisible movement into visible form. Marey's innovations—including the chronophotographic gun and multiple-exposure techniques—laid the foundation for motion analysis in biomechanics, aviation, and cinema. This image represents a key turning point where photography became a scientific instrument for understanding time and motion.

Exploring the Influence of Self-Inclusion across Zero Baseline

Self-inclusion in photography places the creator within the frame, not as subject in the traditional sense, but as an active element of the process. In scientific and experimental contexts, this often takes the form of embodied observation—using one’s own presence as the constant in generating reliable, repeatable data. Whether for calibration, as a control in experimental conditions, or to merge observation with participation, it aligns the act of seeing with the act of being seen. This approach transforms the camera into both recorder and witness of the photographer’s presence, producing images where method and subject converge. Self-inclusion bridges the gap between observer and observed, embedding the maker’s role directly into the visual record.

Exploring the Influence of Time Continuum across Zero Baseline

Time Continuum Study redefines photography’s relationship with the instant. Rather than freezing a fraction of a second, these works allow time to unfold within the image, transforming duration itself into the subject. Through long exposure, sustained observation, or temporal accumulation, motion is absorbed rather than isolated. Light becomes a measure of duration, and the photograph a continuum of experience. By collapsing many moments into one, Time Continuum Study unites stillness and change within a single visible state. The photograph no longer isolates an instant but captures the very passage of time — light acting simultaneously as event and memory.
