髮絲那一縷，是這張的差分點
深炭灰背景壓滿右側留黑，暖琥珀高光只落在顴骨和髮絲邊緣。
✍️ 右側那片黑不是留白湊數，是給桌布模式讓位置——這跟差分立繪留裁切區一個道理，位置得先想好再畫細節。

Set inside a 16:9 widescreen studio portrait frame, a single woman in her early 30s gazes into the camera with a calm, neutral expression, shoulders turned slightly and hair pulled back neatly. Render the head and shoulders crisp and realistic, clean catchlights and natural skin texture intact, while leaving generous dark negative space toward the right so the image still reads well as wallpaper. A soft key light falls off gently with subtle rim separation, the deep charcoal background gradient staying minimal in detail, warm amber highlights meeting cool slate shadows, and a faint layer of film grain finishing the look.

在16:9寬畫幅的影棚人像構圖裡，一位三十歲出頭的女性直視鏡頭，表情平靜中性，肩膀略微側轉，頭髮整齊地束在腦後。頭部與肩膀部分處理得清晰寫實，乾淨的眼神光與自然的皮膚質感一併保留，右側留出充足的深色負空間，讓整張圖作為桌布也能讀起來舒服。柔和的主光自然衰減，帶細微的輪廓分離，深炭灰背景漸變保持極簡的細節，暖琥珀高光與冷石板灰陰影相遇，一層淡淡的膠片顆粒感收尾。
