How does the lighting in Masaccio’s Tribute Money match the actual light in the Brancacci Chapel?

In Masaccio’s Tribute Money, the lighting is carefully designed to harmonize with the physical environment of the Brancacci Chapel. The figures and scenes within the fresco are consistently lit from the upper right, which matches the actual natural light entering the chapel from a window located on the wall to the right of the painting.12

By aligning the painted light with the chapel's real-world light source—indicated by the direction of the cast shadows—Masaccio successfully integrated the artwork into the viewer's space. This technique was part of his broader effort to move away from the arbitrary physical laws of medieval art, instead treating the painting as a "window" that shares the same laws of perspective, space, and light as the reality inhabited by the observer.123
