Adam Walker visits the exhibition Double Vision, curated by Katrina Blannin, at at Lion and Lamb Gallery, London, on view through July 14, 2012.

Walker writes: "As eluded to in the title, this exhibition of contemporary abstract painting sets out to explore a series of binary oppositions: figure and field, surface and depth, chance and system, symmetry and asymmetry. While these are well-traveled avenues of exploration, the quality of the works on display makes revisiting them worthwhile."
