Water is a material, a metaphor, a social space. A moving target for the camera’s eye, water appears and disappears as it changes shape and shifts from one state to another. Tracking the movement of light across the surface of this most elusive subject, generations of photographers have faced challenges both technical and poetic. Effects ranging from crisp focus to ghostly blur and moods that span the playful to the turbulent are on view in this exhibition of works from the LUAG permanent collection. Photographs by Weegee, Stoumen, Kertész, Porter, Bourke-White, Dassonville, and others are included.
