Smartphone Ad Poster — Dark Cinematic Product Shot Prompt

Generate a sleek, dark-themed commercial smartphone poster with bold typography, feature highlights, and cinematic lighting using this Sora 2 prompt. Use it as a Art Conceptuel starting point for GPT Image 2: keep the visual structure and style constraints intact, then swap in your own subject, brand, or scene.

This prompt is organized as structured JSON with fields such as type, subject, typography, and style. Keeping that hierarchy helps the model separate the subject, layout, interface elements, and detail constraints.

Start with small changes to subject, scene, camera, and color, then generate a few variations to compare composition and detail without turning the page copy into keyword stuffing.
