Description
The East Los Angeles Interchange is one of the world’s most complex freeway interchanges — the four-level stack where Interstates 10 and 5 cross and the continuation of I-101 creates a structure of ramps, flyovers, and transitions whose geometric complexity is fully comprehensible only from altitude. The blue hour aerial photograph adds the light trail dimension: a 30-second exposure from a circling helicopter at 300 metres records the headlight and tail light streams of the evening commuter traffic as continuous orange and white ribbon trails across the interchange structure. This image was made at 6:15pm in November when the sun has set sufficiently for the artificial light to be the dominant source while the sky retains deep blue saturation. Shot on a 24-70mm zoom at f/8 from the helicopter’s open door, the city grid extending to the Pacific in the background completes the Los Angeles urban geography.
