Mark Lewis investigates the camera's role in the construction, language, and effect of the cinematic image and its representation of modernity. Most of his films are silent and limited to about four minutes, which is the standard length of a roll of 35 mm film stock. Lewis typically employs a single take, in which the camera slowly and methodically investigates its subject, often linking cinematic technique with the particularities of the location. "Isosceles", one of a series of films shot in London, UK, where he lives, examines a defunct triangular public restroom, stranded at the junction of several streets in the (re)burgeoning area of Smithfield Market, which dates back to the 10th century. The enveloping movement of the camera presents a portrait of this vestige of London's early industrial era, in marked contrast with the surrounding modernized buildings.
