Request Example

{
    "input": {
      "prompt": "The photo: Create a cinematic, photorealistic medium shot capturing the nostalgic warmth of a mid-2000s indie film. The focus is a young woman with a sleek, straight bob haircut in cool platinum white with freckled skin, looking directly and intently into the camera lens with a knowing smirk, her head is looking up slightly. She wears an oversized band t-shirt that says \"Imagen 4 Ultra on Replicate\" in huge stylized text over a long-sleeved striped top and simple silver stud earrings. The lighting is soft, golden hour sunlight creating lens flare and illuminating dust motes in the air. The background shows a blurred outdoor urban setting with graffiti-covered walls (the graffiti says \"ultra\" in stylized graffiti lettering), rendered with a shallow depth of field. Natural film grain, a warm, slightly muted color palette, and sharp focus on her expressive eyes enhance the intimate, authentic feel",
      "aspect_ratio": "16:9",
      "output_format": "jpg",
      "safety_filter_level": "block_only_high"
    }
  }
