Sydney Sweeney 膠捲

A highly constrained prompt for generating a cinematic, vintage-style outdoor portrait of Sydney Sweeney, demanding maximum identity preservation and prohibiting any alteration or beautification of her features. The prompt requires varying the pose naturally while maintaining the same prop (a red lollipop) and applying a strong analog film aesthetic with heavy grain, dust, and a warm brown-orange color cast.

  "prompt": "使用上傳的參考圖像作為絕對身份錨點。保留主體的面部特徵、面部比例、骨骼結構、眼睛、鼻子、嘴唇、膚色、髮際線、髮質、身形和整體相似度，保持最高忠實度。不要美化、理想化或以任何方式改變人物。一張電影級、復古風格的戶外肖像，描繪同一人。每次生成時，自然變化主體的姿勢（例如，輕微身體角度變化、微妙傾斜、頭部傾斜、手臂位置），同時保持相同道具：一個明亮的 {argument name="道具顏色" default="紅色"} 棒棒糖靠近嘴唇或臉部。保持冷靜、自信的表情。主體穿著白色無肩帶上衣和高腰淺藍色破損牛仔短褲。光線在黃金時刻柔和、溫暖且自然。圖像具有強烈的類比film aesthetic，帶有 heavy grain、灰塵、刮痕、微妙褪色和溫暖棕橙色調，類似舊35mm照片。背景輕微模糊，帶有淺景深。構圖保持電影級且一致。",
