Impressionism is a 19th-century art movement that originated with a group of Paris-based artists. Their independent exhibitions brought them to prominence during the 1870s and 1880s, in spite of harsh opposition from the conventional art community in France. The name of the style derives 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 satirical review published in the Parisian newspaper Le Charivari.
Impressionist painting characteristics 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), ordinary subject matter, 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 that became known as impressionist music and impressionist literature.
Radicals in their time, early Impressionists violated the rules of academic painting. They constructed their pictures from freely brushed colours that took precedence over lines and contours, following the example of painters such as Eugène Delacroix and J. M. W. Turner. They also painted realistic scenes of modern life, and often painted outdoors. Previously, still lifes and portraits as well as landscapes were usually painted in a studio. The Impressionists found that they could capture the momentary and transient effects of sunlight by painting en plein air. They portrayed overall visual effects instead of details, and used short "broken" brush strokes of mixed and pure unmixed colour—not blended smoothly or shaded, as was customary—to achieve an effect of intense colour vibration.
