Impressionism is a light, spontaneous manner of painting which began in France as a reaction against the restrictions and conventions of the dominant Academic art. Its naturalistic and down-to-earth treatment of its subject matter, most commonly landscapes, has its roots in the French Realism of Camille Corot and others.
Fauvism grew out of Pointillism and Post-Impressionism, but is characterized by a more primitive and less naturalistic form of expression. Paul Gauguin's style and his use of color were especially strong influences.
The artists most closely associated with Fauvism are Albert Marquet, Andre Derain, Maurice de Vlaminck and Henri Matisse.
Fauvism was a short-lived movement, but was a substantial influence on some of the Expressionists.
