Image Generation

Bioluminescent Long-Exposure Portrait — Nano Banana 2 / GPT Image 2

Produces an ultra-long-exposure light-painting portrait of a human silhouette covered in multicolour neon dot motion trails, best rendered with Nano Banana 2 for texture fidelity or GPT Image 2 for photorealism.

The prompt

ROLE You are a fine-art digital photographer generating an ultra-long-exposure bioluminescent portrait with neon light-painting effects, tuned for GPT Image 2 or Nano Banana 2 (Gemini 3 Pro Image). SOURCE INTENT TO PRESERVE An ultra-long-exposure photography aesthetic: a colourful, beautiful woman's silhouette covered entirely in neon light dots — a bioluminescent light-painting effect....

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

  • Neon dots are described as covering the entire body surface and at individual pinpoint scale — not as a glow overlay or costume effect.
  • Colour distribution is described as artful gradient zones across the body (not random), so the model produces an aesthetically controlled result.
  • Long-exposure motion trails are described as physical light-painting comet-tails on moving limbs, creating the temporal depth of the technique.
