Shifting Light, Shifting Mood: Black Knit Portraits on a Softer Canvas

{
  "portrait_prompt": {
    "full_prompt": "Based on <User Portrait>, preserve the uploaded facial identity and create an indoor editorial portrait of an adult woman sitting at the center seam of a light beige sofa in front of dark wooden horizontal blinds. The subject has very long platinum blonde hair with full soft bangs, wearing a black oversized sweater dress or long-sleeve mini outfit and black pointed-toe heels. She sits centered on the sofa with both knees raised close together, legs extending forward, torso slightly leaning inward, one hand covering part of her mouth and cheek in a thoughtful gesture, the other arm hanging down loosely between the knees, gazing slightly off-camera with a quiet, distant, introspective expression. Shoot as a vertical 3:4 fashion portrait with a clean centered composition, around 50mm to 70mm equivalent, eye-level to slightly lower-than-eye-level camera height, moderate depth of field, keeping the full body and sofa geometry visible. Use strong natural backlight from the window behind the wooden blinds, creating a bright glowing rim light around the hair and shoulders, soft shadow on the face, gentle highlight bloom, and a calm high-end apartment or hotel suite atmosphere. Fujifilm ASTIA inspired color grading, soft skin tones, warm brown wood, creamy beige upholstery, restrained contrast, subtle fine grain, realistic hair strands, photorealistic editorial finish.",
