Working in a signature modulating gray scale, the late Norwegian photographer Tom Sandberg spent decades rendering the world according to an exacting vision, training his eye on the shapes and forms of the everyday—dark abstractions of asphalt and sea, the hard edges of an automobile, an ominously curved tunnel, an anonymous figure casting a shadow—to plumb the nature of photographic seeing. His pictures are subtle yet transformative, studies of stillness that radiate mystery.
