鎖死構圖只換臉的暗調肖像

Start from the uploaded reference photo and rebuild it as a hyper-realistic, low-key, black-and-white fashion portrait. Everything structural has to hold steady: the square crop, camera angle, where the subject sits in frame, the upper-body framing, the tilt of the head, shoulder line, body angle, backdrop, direction of the light, where shadows fall, contrast level, and the grain — none of it should shift, so the same dark editorial mood carries through untouched. The one thing that changes is the subject: swap the person out for whoever appears in the newly uploaded target reference image.

拿上傳的參考照片來重建，做成一張超寫實、低調風格的黑白時尚肖像。結構性的東西都得穩住：正方形裁切、機位角度、主體在畫面裡的位置、上半身取景範圍、頭部傾斜角度、肩線、身體朝向、背景、光線方向、陰影落點、對比度和顆粒感——一樣都不能變，暗調編輯風格的氛圍才能原樣延續。唯一要變的是主體本身：把人物換成新上傳的目標參考圖裡出現的那個角色。
