Seeing Motion Made Visible – Cocking and Day’s Illuminate

Illuminate (2023) by Chelsi Alise Cocking and Jimmy Day marks a foundational moment in the evolving language of photography. For the first time, viewers can see their own motion visualised in real time, as luminous trails suspended in space. This is not post-production, nor performance capture—it is live, reactive image-making, where motion becomes image the moment it occurs.

Custom-coded visualisation software and spatial computing algorithms power this transformation. As participants move through the installation, the system captures their gestures and instantly renders them as abstract visual forms—echoes of the body looping and drifting through space. The result is a photographic process without a shutter: a continuous, choreographic trace of presence.

Here, the act of photographing motion is redefined. For the first time, it is continuous, real-time, and embodied. Illuminate transforms photography from a moment of freezing time into an active, living encounter with it. What’s being captured isn’t a fixed frame, but the fleeting choreography of the body—made visible as it happens through custom-coded spatial visualisation.

The installation transforms unseen motion paths into glowing trails, bridging physical presence and digital space. Illuminate (2023, Chelsi Alise Cocking) uses choreographic interfaces to explore spatial computing and bodily abstraction, producing a magical experience of seeing motion in real time.

Exploring the Influence of Motion Study across Zero Baseline

Motion study in photography is the disciplined observation of movement through sequential or composite imaging. From early chronophotography to today’s high-frame-rate and sensor-based capture, each development has sought to dissect motion into measurable units while preserving the continuity of form. Refinements in optical precision, frame timing, and layered exposures have made it possible to analyse gesture, biomechanics, dynamic systems, and even subatomic traces with increasing accuracy. Whether for science, industry, or art, motion study transforms fluid activity into a visual framework, revealing structures of movement otherwise hidden to the human eye.

1878 MUYBRIDGE – THE HORSE IN MOTION
Muybridge used sequential photography to dissect the gallop into still frames, revealing movement too fast for the eye and transforming how motion could be studied and understood.

1882 ÉTIENNE-JULES MAREY – BIRDS
Using chronophotography, Marey broke down continuous flight into discrete, analyzable frames—laying the foundation for modern studies of motion and biomechanics.

1886 ÉTIENNE-JULES MAREY – SHAKING A FLEXIBLE ROD
Layered multiple phases of movement into a single frame to visualise wave motion.

1887 MUYBRIDGE – ANIMAL LOCOMOTION. PLATE 762
Sequential frames capturing the phases of a bird in flight, offering one of the earliest detailed visual studies of avian motion (bird motion).

1889 ÉTIENNE-JULES MAREY AND GEORGE DEMENY - Pathological Walk from the Front
Among the earliest images to visualise human movement as a sequence, this photograph marked a turning point in understanding motion through time.

1900 A.M. WORTHINGTON - SPLASH
Used spark photography to reveal the fluid structures formed in the instant of liquid impact.

1900 ÉTIENNE-JULES MAREY – AIR MOVEMENT IN A COLLISION WITH OBJECTS OF DIFFERENT SHAPES
Visualised airflow patterns as they moved around and responded to objects of varying shapes.

1973 BUBBLE CHAMBER-CERN-EX-23296
Captured the spiralling paths of subatomic particles through liquid, revealing motion patterns that defined their charge, momentum, and interactions.

2015 LIGHT AS WAVE AND PARTICLE
Captured light behaving simultaneously as both wave and particle, providing direct visual evidence of quantum duality.

2023 CHELSI ALISE COCKING AND JIMMY DAY – ILLUMINATE
Rendered human motion as luminous trails in real time, transforming movement into a continuous visual record of gesture and form.

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.

1886 ÉTIENNE-JULES MAREY – SHAKING A FLEXIBLE ROD
Used his own body to generate repeatable motion patterns, embedding himself directly into the process of visual study.

1889 ÉTIENNE-JULES MAREY AND GEORGE DEMENY
Appeared as their own test subjects, integrating the observer into motion studies for calibration and consistency.

1895 RÖNTGEN – FIRST X-RAY
Exposed his wife’s hand to produce the first X-ray image, making a groundbreaking scientific record through a personal and embodied act.

1898 LOUIS BOUTAN - FIRST UNDERWATER PHOTOGRAPH
Entered the aquatic environment with experimental equipment, embedding himself in the process to test and refine submersible photography.

1935 MAN RAY – SPACE WRITING (SELF-PORTRAIT)
Performed gestures with light during long exposure, transforming self-inclusion into a performative, photographic self-portrait.

2023 CHELSI ALISE COCKING AND JIMMY DAY – ILLUMINATE
Rendered human motion as luminous trails in real time, enacting self-inclusion through gesture and transforming movement into a continuous photographic record.
