Pierre-Auguste Renoir
We are probably looking at the river Seine near Chatou (some ten miles west of central Paris), although the exact site has not been identified. It is typical of the imagery that has come to characterize Impressionism, and Renoir includes several familiar Impressionist motifs, such as fashionably dressed women, a rowing boat, a sailboat, and a steam train crossing a bridge.
If Renoir’s choice of subject is characteristically Impressionist, this is also true of his painting technique. He creates an effect of summer heat and light by using bright unmixed paint directly from the tube and by avoiding black or earth tones. In placing the bright orange boat against the dark blue water, Renoir has deliberately used complementary colors, which become more intense when seen alongside each other.
P.S. The paintings of Renoir are like chronicles of Paris society life. Here you can peek a model known as "fish-face" sitting in a theater box and here's a painting for which Renoir postponed a planned trip to London (what he confessed to the American painter James McNeill Whistler during lunch).
