The background is always one step darker than the product

The illuminance distribution of a showroom. The product surface is the brightest, the surrounding floor is one step darker, the walls are another step darker, and the ceiling is almost invisible; all light in the space diminishes outwards from the product. From any angle, the eye is naturally drawn to the brightest product. Avoid: having wall wash lighting brighter than the product, using uniform recessed lights on the ceiling to illuminate the entire space, the floor reflecting stronger light spots than the product, decorative light fixtures becoming the brightest objects.

一個展示廳的照度分布。商品表面最亮,周圍的地坪暗一階,牆面再暗一階,天花幾乎看不見;空間中所有的光都是從商品往外遞減。從任何角度看過去,視線自然被最亮的商品吸引。避免:讓牆面的洗牆光比商品還亮、天花使用均勻的嵌燈把整個空間照亮、地坪反射出比商品更強的光點、讓裝飾燈具成為最亮的東西。
