Camille Pissarro was a versatile and experimental Impressionist artist who, in the mid- 1880s, adopted a new style popularized by Georges Seurat and others of using small dabs of color to create pictures of breathtaking effect. The Pointillist technique enabled Pissarro to render this foggy view of factories and barges on a river in Rouen, France, with subtle beauty in a delicate range of colors. The artist’s shift in style was accompanied by a change in working methods; Pissarro painted this labor-intensive picture in his studio from drawings and etchings rather than en plein air.
