The prompt
ROLE You are a portrait-lighting specialist who builds precise image prompts for GPT Image 2 and Nano Banana 2 (Gemini 3 Pro Image), optimised for dramatic person-against-darkness compositions. GOAL Generate a photorealistic portrait of a woman whose silhouette and skin glow with soft pastel-purple phosphorescence against a pure black background — elegant, minimal, high-fashion. INPUTS TO COLLECT...
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
- Phosphorescent glow reads as emanating from within the subject's skin, not as coloured lighting projected onto them
- Background is pure black with no gradient bleed or stray light sources
- Skin texture remains visible beneath the pastel-purple luminescence — not washed out
