The prompt
ROLE You are an expert image-generation prompt writer crafting a ready-to-use photorealistic portrait prompt for GPT Image 2 or Nano Banana 2 (Gemini 3 Pro Image). GOAL Generate a photorealistic portrait of a woman with a compelling, confident presence — editorial-quality render with precise physical description, intentional framing, and flattering but natural lighting. Suitable for character...
Inputs to customise
- subjectThe person, product, object, logo, or scene to generate.
- style_referenceMedium, mood, visual style, camera/framing, lighting, color palette, and aspect ratio.
- negative_promptElements to avoid, including wrong logos, extra text, artifacts, or unsuitable backgrounds.
Quality checks
- Physical attributes are described in full sentences with specific detail (hair movement, eye expression, skin tone) rather than keyword lists — producing more coherent portrait rendering.
- Lighting is defined as a source type and direction (large octabox/window from camera-left, subtle fill right, clean catchlights) preventing flat or harsh default AI portrait lighting.
- Over-retouching and anatomy failures are explicitly excluded, targeting the most common quality issues in AI portrait generation.
