Artists have used photographs for many purposes, but this exhibition focuses on their use as a drawing board. It begins with Rodin, whose innovative use of photography is now well known, and comes up to the present day, with works by Hew Locke, whose graffiti-like over-drawing references both Rodin’s sculptures and Rodin’s graphic interventions.

Drawing on Sculpture includes around thirty works, highlighting the different reasons for sculptors to draw on photographs. These drawings provide a visual commentary on how sculptors think about their work and explore colour, outline, surface, layering, scale and meaning.

In some cases the artists' annotations are practical - dealing with issues of enlargement or with problem areas - while other modifications extend to the complete recontextualisation of the original work. The drawn line is also seen to be used as a way of animating the sculpture, as with the works of Paul Neagu or Tony Cragg, in which the line whips round the static form as if it were the wind. In this hinterland between two and three dimensions, impossible sculptures are allowed to exist.
