Synopsis

What if light were the pulse of our planet? In Tracing Light, filmmaker Thomas Riedelsheimer (Rivers and Tides, Touch the Sound) leads us from the windswept Outer Hebrides to Germany’s Max Planck research labs.

Collaborating with artists Semiconductor, Julie Brook, Brunner/Ritz, and physicists probing single-photon pulses, he stages experiments that echo nature’s own light cycles: the dawn glow on tidal sands, the sparkle of bioluminescent plankton, the green flash of photosynthesis. Laser bursts and marble reflections become metaphors for climate rhythms and ecosystem balance. Each frame asks: how does light shape life, time, and seasonal change?

With painterly cinematography and an immersive soundscape, Tracing Light fuses art and science to illuminate our world’s delicate reliance on light, and urges us to safeguard the harmony it sustains.
