Retouching is the process of making subtle adjustments and enhancements to a work of art, particularly paintings, to restore its visual integrity while maintaining the artist's original intent. This technique is essential in conservation as it aims to fill in lost areas, tone down overpaint, and integrate patches seamlessly, all while being reversible and easily identifiable in the future. Retouching requires a deep understanding of the original materials and techniques used in the artwork.
