At night, the Margaret Hunt Hill Bridge's 58 pairs of high-strength steel cables catch the ambient light of the city and arrange themselves into something that Greg titled "Filamentis" — the Latin for filaments — and the name describes the image exactly: parallel threads of illuminated cable converging on the arch above in a pattern that suggests both engineering and biology. Shot on the Leica M11, the cables resolve as individual elements rather than merging into glare, the rangefinder's quiet operation suited to the long exposure the scene required. The arch itself disappears into the upper frame, which is the right compositional choice: what matters here is the repetition, the rhythm, the way 116 cables can read as a single musical event. Calatrava designed bridges to be seen.
