James Kalm visits an exhibition of works by Robert Ryman at Dia:Chelsea, New York, on view through June 18, 2016.

Kalm notes: "This show presents a wide survey of various experimental and conceptual approaches to the project of painting. Since beginning his practice in the mid 1950s, Ryman has limited his materials to mostly white paint, square formats, and an extraordinary variety of grounds and surfaces onto which he applies paint. These twenty-two paintings record the evolving bodies of work the artist has developed from the late 1950s until the mid 1980s."
