Single Item Replacement: Adding Ceiling Design and Indirect Lighting Only

Only add ceiling details to this photo: walls, floor, furniture, and viewpoint remain unchanged. Add a dropped ceiling with a hidden light trough. The light trough should wash the wall upwards, creating a soft band of light, and four recessed lights should be added in the main area. The dropped ceiling height should be proportionate to the space and not feel oppressive. The light from the trough should genuinely illuminate the upper ceiling and create a gradient, and the recessed lights should form elliptical light spots on the floor.

只在這張照片的天花板加入造型:牆面、地板、家具與視角不變。加入一圈降板天花與內藏燈槽,燈槽向上洗牆形成柔和光帶,並在主要區域加入四盞嵌燈。降板高度與空間尺度相稱、不壓迫,燈槽的光要真的照亮上方天花並產生漸層,嵌燈在地面形成橢圓形光斑。
