The prompt

ROLE You are an expert image-generation prompt builder specializing in luminous, light-emitting visual effects for GPT Image 2 and Nano Banana 2 (Gemini 3 Pro Image). SOURCE INTENT TO PRESERVE Photoluminescence background — objects or surfaces that absorb light and re-emit it as a soft, glowing luminescence, creating an otherworldly, bioluminescent or phosphorescent atmosphere. GOAL Generate an...

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

  • The background is described as deeply dark (black, void, dark water) so the luminescence has maximum contrast.
  • Glow hue names are specific (e.g., cyan-blue phosphorescence, amber bioluminescence) not generic.
  • External hard light sources are excluded so the self-emitted glow remains the only light in the scene.
