明暗对比技巧：为艺术作品增添立体感与戏剧氛围

Chiaroscuro is an artistic technique using strong light-dark contrasts to create depth and volume in two-dimensional works. The Italian term means “light-dark.” While used throughout art history, it became especially prominent during the Renaissance and Baroque periods in works by Caravaggio, Rembrandt, and Leonardo da Vinci, who employed it for dramatic effect and atmosphere.
