Grazing Light for Textured Surfaces

A light source specifically illuminating a rough surface with grazing light. A linear light is hidden in a ceiling recess only ten centimeters from the stone wall, with light almost parallelly sweeping down the entire wall; every protrusion of each stone casts a short, deep shadow below it, amplifying the three-dimensionality of the entire wall several times over. The light spot gradually fades from top to bottom. The adjacent smooth wall does not have this treatment. Avoid: letting light directly illuminate to eliminate shadows, placing the light source far from the wall, using highly diffused soft light, also using grazing light on smooth surfaces.

一道貼著粗糙表面照射的燈光。線型燈藏在距離石牆只有十公分的天花凹槽裡,光幾乎平行地向下掃過整面牆;每一塊石頭的凸起都在下方投出一道短而深的陰影,整面牆的立體感被放大數倍。光斑從上往下逐漸變淡。旁邊的光滑牆面沒有這樣的處理。避免:讓光正面照射消除陰影、把光源放在遠離牆面的位置、使用高擴散的柔光、對光滑的表面也使用掠射光。
