This document provides an overview of realism and impressionism in art between 1840-1890. It discusses key realist artists like Courbet and Millet who depicted everyday subjects and the working class. Photography's rise challenged painting to represent reality. Impressionism emerged in the 1860s with artists like Monet, Renoir, and Manet focusing on momentary visual impressions and light. They used loose brushwork, vivid colors, and painted outdoors. The movement influenced Neo-Impressionists like Seurat who divided colors optically. It also discusses Post-Impressionists like Van Gogh, Gauguin, and Cézanne who were influenced by Impressionism but developed individual symbolic styles.
