grainy 1980s cinematic portrait

Transform the uploaded photo into an authentic 1980s cinematic portrait.
Keep the person’s face, facial features, identity, and natural expression unchanged.
Give the image a vintage 1980s Indian film aesthetic with retro fashion, classic hairstyle, warm nostalgic lighting, subtle film grain, soft analog colors, realistic skin texture, slight camera flash, shallow depth of field, and an old-film photography look.
Add a tasteful vintage background with period-accurate details, creating a stylish, candid, nostalgic 1980s photograph that looks like it was genuinely captured on an analog camera in the 1980s.

Copy the complete prompt and use your own reference photos where requested.
