Relight a subject from any direction

Relight Figure 1 using the luminance map from Figure 2 (light source from the left front). Only change the lighting and shadows of the existing image. Preserve the exact original composition, camera angle, background, scene geometry, crop, and all existing subjects and objects. Do not add, remove, replace, or invent any people, faces, bodies, vehicles, clothing, props, signs, or background elements.
