| | | Accent Lighting of Three Dimensional Objects "Key and fill" Is an effective technique for accentuating the three-dimensional character of an object. This technique entails the use of key and fill lighting from two sides of the object. Key lighting is a hard (more direct and intense beam) accent light used to create shadows and to highlight an object's form and texture. Fill light is a softer (wider beam) light thrown from the opposite side of the object to soften the shadows, making the object appear more natural. Other techniques can also be applied to further accentuate the unique character of an object, such as silhouetting an object from behind. | | Accent Lighting of Flat Artwork Flat art is ideally illuminated by a source striking its surface at a 30° angle. This eliminates veiling reflection (glare) from bouncing into a viewer's eye, and prevents casting a shadow of the viewer onto the artwork. To determine the correct distance from the wall you can use the formula below or quick reference chart. The formula below is used to calculate luminaire distance from the wall for a 30° aiming angle where H = Distance from the center of the face of the lamp to the aiming point and D = Distance from the wall to the center of the face of the lamp. (The aiming point should be 1/3 down from the top of the picture or object.) D = H x .5774 Example: D = 4.0' x .5774 = 2.31' or approximately 2'-4" | | |
