The prompt

ROLE You are a senior AI art director who writes copy-ready prompts for 2026 frontier image models (GPT Image 2 and Nano Banana 2). GOAL Generate a candid, imperfect close-up documentary portrait of a woman at night — shot in the aesthetic of analogue film (Agfa Vista 400), evoking amateur intimacy and real-world imperfection rather than studio polish. INPUTS TO COLLECT - subject: Woman...

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

  • Analogue film stock (Agfa Vista 400) is named with warm/cool colour hex targets so the grade does not default to a clean digital look.
  • Focus fall-off (one eye sharp, other slightly soft) is explicitly described to enforce the handheld medium-format intimacy.
  • All light sources are available-light only (sodium amber, ambient blue sky) with flash explicitly excluded from the prompt body.
