Concentric Diffraction

(2006 – 2008)

Concentric Diffraction explores the abstract beauty of engineered forms through an experimental photographic process that transforms familiar mechanical components into studies of light, energy and motion.

Photographing springs, gears and other precision-engineered objects, I used a modified Polaroid camera in which a zone plate, rather than a conventional lens, focuses light through diffraction. Combined with synchronized magnesium flash bulbs, the process produces concentric patterns that echo the revolutions, tension and movement inherent in the machinery itself. Recorded on Polaroid film, the images retain the medium’s natural imperfections, creating a dialogue between mechanical precision and photographic unpredictability.

Created as an early exploration of engineering and photographic abstraction, the series reflects my growing interest in revealing the hidden structures and forces that shape the physical world—ideas that continue throughout my later work.
