Martha Lucy, deputy director for education and public programs at the Barnes Foundation, said Albert C. Barnes, the founder of the museum, probably saw photography as a tool for documentation rather than a form of art. For this reason, there is no photography in the art collection at the Barnes Foundation. However, Lucy said photographs of early 20th century Paris can help visitors relate the paintings at the Barnes to the real world. “Live and Life Will Give You Pictures: Masterworks of French Photography, 1890–1950” is the Barnes Foundation’s first photography exhibit. The exhibit will run until Jan. 9.
