Final answer:
Edward Weston utilized perspective in his photograph 'Artichoke Halved', where the leaves' varying distances create depth. Scale and proportion influence the viewer's perception of depth and focal points in two-dimensional art.
Step-by-step explanation:
Edward Weston revealed a natural example of perspective in his photograph titled Artichoke Halved, as the artichoke leaves increase and decrease in distance. The concept of scale and proportion in art refers to the relative size of one form in relation to another, often utilized to create illusions of depth and focal points in two-dimensional artworks. The larger form typically appears closer to the viewer, while the smaller one seems further away, contributing to the overall sense of depth in a piece. This technique has been employed by various artists to enhance the three-dimensional illusion in their work, as seen in Pietro Perugino's use of linear and atmospheric perspective in Christ Handing the Keys to St. Peter.
