Outdoor painting, often referred to as plein air painting, involves creating artwork in natural settings rather than in a studio. Artists set up their easels in parks, gardens, or scenic landscapes to capture the beauty of the environment directly. This practice allows them to observe and depict the changing light, colors, and atmosphere of the outdoors. The technique has roots in the Impressionist movement of the late 19th century, where artists like Claude Monet and Pierre-Auguste Renoir popularized painting outside. Outdoor painting encourages spontaneity and a direct connection with nature, making it a favorite among both amateur and professional artists.
