Part of the shadow area is illuminated by reflected light. The shadow area is all area not in direct light. It is never darker than a cast shadow or lighter than the shadow area that appears on the periphery of the area in direct light. Without reflected light, all the viewer would see is the lit side, resulting in an unconvincing image. The color of the object is often most true in this area because direct light can wash out local color. For example, the shadow side of a sphere is slightly illuminated by light bouncing off the floor and onto this side of the object. Reflected light, or bounced light, is light on the dark side of the form that has been reflected onto the form by adjacent surfaces. This is important to understand because assuming that a highlight simply indicates the direction of a light source will result in a misleading rendering of the shadows.ĭirect light refers to any area on the form that directly receives light from the light source. The highlight is NEVER at a 90-degree angle to the light source, but rather between that angle and where the artist’s line of vision hits the object. Highlights are usually small and intense spots of near-white. If the surface has a protuberance somewhere else in direct light, the highlight may be on the protuberance in the area closest to the light source. If the surface is irregular, the highlight may be at the crest of the surface in direct light. Highlight refers to the bright reflection that occurs where the light directly hits the form. Light hitting a cylindrical object and the resulting pattern of shadow (D), highlight (HL), darkest dark, or core shadow (DD), and reflected light (RL). Photo by Marco Bianchetti / Unsplash Forms of Shadow and LightĪrtists refer to six basic concepts when describing the behavior of light on a form, listed here in order of brightness: highlight, direct light, reflected light, shadow, core shadow and cast shadow. For this reason, it is important for beginners to understand the nature of shadows and light. Rather, it is usually in an environment in which light is bouncing around in several directions.
