Stephen Cornford's Spectral Index shows us how we use rocks to look for rocks.

Artist Statement

Digitisation has shifted the materials on which our media technologies rely. The minerals and metals required for digital imaging are the same as those required for energy transition away from fossil fuels. There is currently a new resource race underway, with nation states and political blocks scrambling to ensure secure supplies of these critical raw materials. This race is both driven by and reliant upon visual cultures, a recursive circularity in which images are used to produce minerals which are used to produce images.

This single-screen video work considers the role of the ‘spectral index’ in framing our relationship with landscapes that are perpetually surveilled by orbital satellites and aerial drones. A spectral index is a mathematical image function in which different wavelengths of the visible and infrared spectrum are combined to produce false colour images that analyse different terrestrial conditions. To gaze at the earth through these instrumental lenses presumes both ownership and functionality of the planetary surface below.

Artist Biography

Stephen Cornford is a media artist who works with consumer electronics, critiquing the ideologies they embody and the constitutive role they have come to play in our lives. His current research is concerned with the toxicity of digital media, the complex metallurgy of ubiquitous technologies and relationships between planetary and photographic space.

Much of his recent work has been made in collaboration with scienctific researchers. He has worked alongside commercial geophysicists prospecting for technology metals in Europe and volcanologists studying magma crystallisation with X-rays. His practice often employs laboratory processes or scientific imaging, using geological furnaces to transform electronic waste or optoelectronics facilities to damage cameras.

In 2018 he completed a PhD affiliated to the Archaeologies of Media & Technology Research Group at Winchester School of Art. Stephen has had solo exhibitions in Tokyo, Berlin, Brighton, Bergen, Ljubljana & London and his work has been included in group exhibtions at the ZKM Center for Art & Media, Karlsruhe; ICC, Tokyo; Haus der Electronische Kunst, Basel; Sigma Foundation, Venice; Finnish Museum of Photography and Coventry Biennial.
