Wall washing and grazing: Two ways to light the same wall

A nighttime view of a stone facade, with the left and right halves of the image contrasting two different lighting methods. The left half is wall washing: the luminaires are further from the wall, and the light falls on the wall at a larger angle, with uniform brightness that changes little from top to bottom. The stone surface appears smooth, and the joints are not obvious. The right half is wall grazing: the luminaires are placed close to the base of the wall, and the light almost parallels the surface, sweeping upwards. The irregularities, chisel marks, and joints of each stone cast long, thin upward shadows, greatly enhancing the texture, but the brightness rapidly diminishes from bottom to top. There is a clear dividing line between the two halves. The overall color temperature is a consistent warm white. Avoid: making both sides look the same, adding colored light, illuminating the background sky, including superfluous decorative luminaires.

一面石材外牆的夜景,畫面左右兩半採用兩種不同的照明方式作對比。左半是洗牆:燈具離牆較遠,光以較大角度落在牆上,亮度均勻,從上到下幾乎沒有變化,石材的表面看起來平滑,接縫不明顯。右半是擦牆:燈具緊貼牆腳,光幾乎平行地貼著表面往上掠過,每一塊石材的凹凸、鑿痕與接縫都投出向上的細長陰影,質感被大幅強化,但亮度從下往上快速衰減。兩半之間有一道清楚的分界。整體色溫一致的暖白。避免:讓兩側看起來一樣、加入彩色光、把背景天空打亮、出現多餘的裝飾燈具。
