This project explores the invisible terrain of WiFi networks in urban spaces by light painting signal strength in long-exposure photographs.
A four-metre long measuring rod with 80 points of light reveals cross-sections through WiFi networks using a photographic technique called light-painting.
This builds on a technique that was invented for the 2009 film ‘Immaterials: the Ghost in the Field’ which probed the edges of the invisible fields that surround RFID readers and tags in the world. It also began a series of investigations into what Matt Jones richly summarised as ‘Immaterials’.
An interesting and quiet exploration of the city and one of its many infrastructures/interfaces.
