Sydney Sweeney 复古胶片肖像提示词

{
  "prompt": "Use the uploaded reference image as the absolute identity anchor. Preserve the subject’s facial features, facial proportions, bone structure, eyes, nose, lips, skin tone, hairline, hair texture, body shape, and overall likeness with maximum fidelity. Do not beautify, idealize, or alter the person in any way. A cinematic, vintage-style outdoor portrait of the same person. For each generation, vary the subject’s pose naturally (e.g., slight body angle changes, subtle lean, head tilt, arm positioning) while keeping the same prop: a bright {argument name="prop color" default="red"} lollipop held near the lips or face. Maintain a calm, confident expression. The subject wears a white strapless bandeau top and high-waisted light-blue distressed denim shorts. Lighting is soft, warm, and natural during golden hour. The image has a strong analog film aesthetic with heavy grain, dust, scratches, subtle fading, and a warm brown-orange color cast, resembling an old 35mm photograph. Background is softly blurred with shallow depth of field. Framing remains cinematic and consistent.",
