Disasters of War (Imperial War Museum, London)

Three ages of European war through the etchings of Jaques Callot, Goya and Otto Dix. Black-and-white flashes of horror, mass executions, madness and blood everywhere. To 26 Sept

Chuck Close (Hayward Gallery, London)

One hundred years after his birth, Alfred Hitchcock lives. Group show looks at his legacy in art, most cunningly in the Phoenix Tapes. To 3 Oct

As Dark As Light (Venues around Cornwall)

A countywide contemporary art festival, focusing on the solar eclipse. James Turrell's open-air sky-dome, The Elliptic Ecliptic, is the sight to see. To 20 Nov
