低調打光

讓陰影佔據較大比例，以局部照明選擇觀眾能看見的資訊。

提示詞

Use Low-Key Lighting: let deep controlled shadow occupy most of the existing corridor, while a narrow soft key from upper camera-left selectively reveals the existing face, braid, upper torso and a few coat folds. Retain enough shadow detail to recognize the original outfit; do not simply underexpose the entire scene uniformly. Keep a clear illuminated focal area with darker surrounding space. No silhouette or rim outline.

其他技法

分割線會自己來回移動。把游標移上去就會停下來，這時可以自己拖。

效果對照

基準圖裡，Biwa 身後的牆與廊道都清楚可見。低調打光讓大部分空間退入陰影，只留下臉、肩部和幾處白外套亮面。視線集中在人物上半身，周圍暗處則留下較多未知，形成收斂而緊張的氣氛。
