This is where things get technical. With the advent of photographic printing, young Impressionist painters like Édouard Manet and Edgar Degas developed a new way of looking at the world: as the camera would. The asymmetry and ambiguity of its images, its chemical record of light, excited these artists. Simultaneously, photographers were working to capture the painterly effects of the Impressionists. This exhibition probes an evolving relationship between two mediums. —J.V.
