“…For example, lightness perception can depend on the geometric interpretation of a visual scene, such as curvature (Knill & Kersten, 1991;Pessoa, Mingolla, & Arend, 1996), transparency (Adelson, 1993), and depth (Gilchrist, 1977;Schirillo & Arend, 1995;Schirillo, Reeves, & Arend, 1990). Also, simply inducing the observer to interpret a scene differently (whether a luminance boundary is a shadow or an object border) affects lightness accordingly (Gilchrist, Delman, & Jacobsen, 1983).…”
