Modernist street photography was one of the first movements that secured photography’s place in museums as a fine art in its own right. Among the important early pioneers of the style, Helen Levitt photographed her home neighborhood of Brooklyn beginning in the 1930s and developed a distinctive style that secured her position in the canon. Children were her most common subject. This eerie scene of masked children on Halloween illustrates street photography’s core principle of capturing evocative moments in ordinary life.
