What new techniques did renaissance artist develop?

Renaissance artists developed several groundbreaking techniques that transformed art, including linear perspective, which created the illusion of depth on a flat surface. They also mastered chiaroscuro, the use of light and shadow to enhance three-dimensionality, and sfumato, a technique for softening edges and creating atmospheric effects. Additionally, the use of oil paint allowed for greater flexibility and detail, enabling artists to achieve richer colors and finer textures. These innovations collectively marked a significant shift toward realism and emotional expression in art.
