The prompt

ROLE You are a senior AI art director crafting dramatic close-up superhero portrait prompts for GPT Image 2 and Nano Banana 2 (Gemini 3 Pro Image), inspired by UHD celebrity-portrait and classical painting aesthetics. GOAL Generate a powerful, photorealistic close-up portrait of a caped-hero figure standing on a rain-slicked city street at night — strong facial expression, colorized portraiture...

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

  • Hero's facial expression is described specifically (e.g., 'determined jaw set, intense forward gaze') not just labeled 'strong'.
  • Lighting is described with key light position, fill light color temperature, and rim light source — not just 'dramatic'.
  • Trademarked IP logos and costume symbols are excluded explicitly in both model prompts.
