The Impressionist movement was founded in Paris in 1874 when a group of artists including Monet, Degas, Renoir, Pissarro, and Sisley held their first exhibition. Key to Impressionism was painting outdoors (en plein air) and using short brush strokes and pure colors to capture light and atmosphere. The movement sought to depict reality based on optical visual perception rather than strict adherence to traditional techniques. Major Impressionist works explored themes of modern life and leisure activities through the use of bright colors, loose brushwork, and candid scenes of nature.
