Geographies of Seeing, curated by Lighthouse and Brighton Photo Biennial, draws together a collection of Trevor Paglen’s celebrated photographic work which explores and documents hidden worlds.

The exhibition is focussed on two bodies of work. The Other Night Sky uses data from an international network of amateur satellite watchers to track and photograph classified spacecraft. Echoing the efforts of historic astronomers, Paglen documents astral movements that don’t officially exist.

In the series Limit Telephotography, Paglen adapted the super-strength telescopes normally used to shoot distant planets, to reveal top-secret U.S. governmental sites, sometimes 65 miles away from his camera; covert bases, so remote they cannot be seen by an unaided civilian eye from any point on Earth.
