Impressionism . The name of the style is derived from the title of a Claude Monet work, Impression, soleil levant (Impression, Sunrise), which provoked the critic Louis Leroy to coin the term in a satiric review published in the Parisian newspaper Le Charivari.
Characteristics of Impressionist paintings include relatively small, thin, yet visible brush strokes; open composition; emphasis on accurate depiction of light in its changing qualities (often accentuating the effects of the passage of time); common, ordinary subject matter; the inclusion of movement as a crucial element of human perception and experience; and unusual visual angles. The development of Impressionism in the visual arts was soon followed by analogous styles in other media which became known as Impressionist music and Impressionist literature. source : wikipedia.
