Shadows Without Edges: Fully Diffused Rooms

An interior with no sharp shadows. All light sources are large-area and diffused: a window covered by a sheer curtain, indirect light running along the junction of the ceiling and wall, a fabric-covered floor lamp. There are no narrow-angle spotlights or exposed point light sources. Consequently, the shadows cast by objects on the floor and walls are extremely soft and blurred, with no clear outlines—the shadow of a table leg has no edge, and a person's shadow is just a slightly darker area. The texture of materials also shows only subtle light and dark undulations rather than hard-edged highs and lows. The overall effect is like natural light on a cloudy day. Avoid: using narrow-angle spotlights and recessed lights to create sharp shadows, allowing direct sunlight to enter and form clear light spots, adding dramatic accent lighting, depicting shadows with clear boundaries.

一個沒有任何銳利陰影的室內。光源全部是大面積且被打散的:一整片薄紗覆蓋的窗、一道貫穿天花與牆交接處的間接光、一盞布罩的落地燈。沒有任何窄角的投射燈與裸露的點光源。因此物件在地面與牆上投下的陰影是極為柔和的暈開,找不到明確的輪廓線——桌腳的影子沒有邊,人的影子只是一片略暗的區域。材料的凹凸也因此只有微弱的明暗起伏而不是硬邊的高低。整體像陰天的自然光。避免:使用窄角投射燈與嵌燈製造銳利陰影、讓直射陽光進入形成清楚的光斑、加入戲劇性的重點打光、把陰影畫成有明確邊界。
