Impressionism was a 19th century art movement. Characteristics of Impressionist paintings during this time include visible brush strokes, open composition, and emphasis on light. Some artists during this time were Claude Monet, who did paintings like "The Haystack, End of Summer and Rouen Catherdral, and Renoir who did paintings like, Moulin de la Galette, dance in the city, and Luncheon of the boating party.
Post-Impressionists extended Impressionism while rejecting its limitations: they continued using vivid colours, thick application of paint, distinctive brushstrokes and real-life subject matter, but they were more inclined to emphasize geometric forms, to distort form for expressive effect, and to use unnatural or arbitrary color. Some artists during this time were Vincent Van Gogh, Georges Seurat, and Paul Cezanne.
