An angle of incidence significantly less than 30° causes extreme shadowing on exhibits. Textures caused by brushstrokes or reliefs often appear exaggerated and shadowing is possible from picture frames. Despite the steep angle of incidence and high illuminance, only a low impression of brightness is created on the picture surface.
