Vintage 1970s Retro Denim Portrait

Create an ultra-realistic vintage 1970s-style portrait of a young South Asian man standing outdoors in front of a softly blurred natural background and an old vehicle. He is wearing an open blue denim shirt with a wide collar, visible chest hair, and two layered gold chains. Maintain his natural facial features, dark textured hair, mustache, short beard, medium skin tone, and calm, serious expression. Use warm golden-hour lighting, realistic skin texture, natural facial proportions, shallow depth of field, cinematic composition, and authentic analog film photography. Add subtle film grain, faded warm tones, dust particles, light scratches, and a slightly worn vintage photo border. The final image should look like a real photograph from the late 1970s, not AI-generated, with realistic lighting, shadows, fabric texture, and natural imperfections.
