<human>:  I want to know the differences between impressionism and post-impressionism in art.
<bot>: Impressionism in art is characterized by the use of light and color to create a shadowy, outdoor atmosphere. Artists often used broken brushstrokes to give their works a sense of immediacy and spontaneity. Subjects often depicted in Impressionist art were landscapes, portraits, and ordinary life.Post-Impressionism was a movement that followed Impressionism by introducing a more exaggerated, abstract style of art. Color and brushstrokes were used to render scenes with greater emotional intensity. Geometric forms and strong outlines were used to create an illusion of greater depth. Whereas the Impressionists focused on capturing the ever-changing effects of light and atmosphere, Post-Impressionists emphasized the expressive potential of their compositions. While Impressionist painting often featured scenes from everyday modern life, Post-Impressionism featured more symbolic, dreamlike and exotic scenes.
