Nine-panel 9:16 idol photobook (strict identity lock)

Generate a 3x3 grid of nine photos in a 9:16 vertical format, forming a complete photo series featuring the same young female idol. The subject in all nine photos must be 100% consistent in facial features, face shape, hairstyle, body proportions, and overall identity. Skin should be hyper-realistic, retaining natural texture without excessive smoothing or retouching. Makeup should be light and clean, with subtle highlights and minor imperfections. Hairstyle should be long, voluminous, dark hair, maintaining consistency across all nine photos with only slight natural variations. Clothing should be a uniform white shirt and short bottoms, with a consistent style across all nine photos. The setting should be a simple indoor or studio environment with clean walls, soft window lighting, and a uncluttered background. Lighting should be soft, diffused natural light with low contrast and a slightly soft-focus, film-like quality. The nine images present: standing naturally and looking to the side; a slight movement facing the camera; a gentle turn of the head with a soft gaze; a slight tilt of the head; a close-up of the camera with a slight smile; a turning movement; a casual sitting or leaning posture; a half-turn and a look back; and a relaxed expression close to the camera. The overall feel is like an idol photobook—intimate, soft, and natural. Requirements include hyper-realism, 8K detail, slight film grain, and a dreamlike yet realistic aesthetic.

Which model should you use?

Prefer GPT Image 2 when…

  • You need crisp on-image typography, posters, or UI-style compositions and want an OpenAI-native stack.
  • Your brief is long, rule-heavy, or reads like a spec sheet (materials, layout, exact wording).
  • Lower Photor credits at 1K–2K fit the experiment budget while you tune prompts.

Prefer Nano Banana 2 when…

  • You want faster turnaround and more iterations per dollar, especially at 4K.
  • You rely on Google Search grounding for factual or reference-heavy prompts.
  • You need explicit PNG/JPEG control or heavier multi-reference image-to-image on the dedicated tool page.

Practical decision rule

Use Nano Banana 2 to explore composition and speed, then try GPT Image 2 on the same prompt when text fidelity or “single-shot” layout polish matters most.

Independent write-ups disagree on “winner” by benchmark; treat any headline scores as directional and validate on your brand assets.
