It’s a history not often told -- that of late-19th-century artists using the camera as amateur enthusiasts, taking photos of their family, friends and travels, rather than to produce studies for their paintings. Such is the scope of “Snapshot: Painters and Photography, Bonnard to Vuillard,” an exhibition inspired by curator Elizabeth W. Easton’s discovery, 20 years ago, of never-before-seen photos in the archives of the French painter Edouard Vuillard.
