Floor lamp by the sofa: Reading light should come from behind the shoulder

A night scene of a person reading on a single sofa. The floor lamp is placed to the side and slightly behind the sofa, with the lamp head slightly above the sitting person's head. Light comes from behind and above the shoulder, falling directly onto the book pages. The pages are bright, the text is clear, and the person's body does not cast a shadow on the book, nor do the eyes directly see the light source. On the other side of the image, an incorrect configuration is contrasted: the floor lamp is placed directly in front of the person, light shines directly into the eyes, the book pages reflect glare, and the person has to squint. The lamp models are identical; only their positions differ. The rest of the room maintains low brightness, with only the reading area illuminated, forming a clear activity zone. Avoid: Drawing the two configurations identically, having hand shadows appear on the book pages in the correct configuration, lighting up the entire room, using a main ceiling light instead of a floor lamp.

一個人坐在單人沙發上看書的夜景。立燈設在沙發的側後方,燈頭高度略高於坐姿的頭頂,光從肩膀後上方越過,直接落在書頁上。書頁明亮、字跡清楚,而人的身體沒有在書上投下陰影,眼睛也不會直接看到光源。畫面另一側以錯誤的配置對照:立燈設在人的正前方,光直射眼睛,書頁反光,人必須瞇眼。兩者的燈具型號相同,只有位置不同。房間其餘部分維持低亮度,只有閱讀區被照亮,形成一個明確的行為區域。避免:把兩種配置畫成一樣、讓正確配置的書頁出現手部陰影、把整個房間打亮、使用天花主燈取代立燈。
