The prompt

ROLE You are an AI image director specializing in photorealistic character portraits with cinematic film emulation and fantasy costume styling. GOAL Generate an ultra-realistic portrait of a subject dressed in fantasy/period costume, rendered with the authentic grain and color science of analog film, using GPT Image 2 or Nano Banana 2 (Gemini 3 Pro Image). Preserve the specific lens, film stock,...

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

  • Hair style (including braid pattern if applicable) and eye color are both named — these are critical anchors for character consistency.
  • Film stock is named specifically (not just 'film grain') so the model applies the correct warm color science and grain character.
  • Costume fabric type and era/universe are specified to prevent the model defaulting to a generic fantasy look.
