Associate Professor of American Studies Laura Saltz will speak on the influence literature and photography exert on each other at the Penobscot Marine Museum’s conference “Exploring the Magic of Photography: Painting with Light.” The conference, to take place Nov. 1 in Belfast, Maine, will focus on the influence of photography on interpretations of self and culture and will complement the museum’s collection of more than 140,000 photographs that document 19th- to mid-20th-century life in New England.
