The way lighting affects a space's atmosphere and perception can be greatly altered by selecting the appropriate illumination approach. Our perception of light can be influenced by a variety of circumstances; it's crucial to take into account a fixture's location as well as its brightness, hue, and saturation. Wall washing or wall grazing are the two main methods used to illuminate a wall's surface, which adds visual interest to the room. To achieve the desired look, you must combine the wall lighting technique with the appropriate wall type (textured or smooth).
Wall Washing and Wall Grazing. What is the difference?
When a wall is evenly lighted from top to bottom, it's known as wall washing. This technique, which is frequently used to smooth, light-colored, matte-finished walls, conceals flaws or faults by removing shadows. The wall washing technique is perfect for emphasising a particular focal point since it highlights the vertical surface, giving the impression that smaller areas are larger. Depending on the wall's colour, wall washing might improve the room's overall lighting.
By exposing the texture's design and producing dramatic shadows, wall grazing draws attention to textured vertical surfaces. By directing the occupant's attention to the texture, the shadows take centre stage on the wall. To get the desired grazing effect, position the fixture such that the light beam will strike the wall at a narrow angle.
Fixture Positioning for Washing and Grazing
Installing the light fixtures at or above ceiling height and two to three feet away from the wall will allow them to efficiently "wash" down vertical space and provide a wall-washing effect. In order to allow the light to spread out at a larger beam angle, the luminaires should also be placed far enough from the wall. To get the washing effect, position the light fixture at eye level or towards the centre of the wall or focal point you wish to emphasise. In certain situations, fixtures can also be positioned at or below floor level to facilitate washing.
To produce a wall grazing effect, the luminaires should be placed closer to the wall where the light is focused. The distance between the light and the wall should not exceed 12 inches. For a seductive up-lighting effect, the lights can be positioned on the ground and shine upward.
Summary
Each technique will draw attention to walls by altering how particular areas or surfaces seem to the human eye, depending on the impression you wish to accomplish. Wall washing removes imperfections from a flat surface and draws attention to the wall's qualities. On the other hand, wall grazing highlights textures and makes the wall itself the room's focal point.
