GPT-Image-2 Case Study · Poster to Subway Lightbox

真实业务里很常见的需求不是“设计一张新海报”，而是“把现成 KV 放进真实媒介里看效果”，这个案例就是标准示范。

Transform the provided tea poster into a realistic metro-station lightbox mockup while preserving the poster artwork and Chinese typography as much as possible. Show the poster behind glossy glass in a vertical illuminated advertising frame on a clean subway platform wall. Add subtle reflections, brushed metal frame, floor tiles, soft overhead transit lighting, and a few blurred commuters in the distance. Keep the poster straight, legible, and dominant; do not redesign the poster, do not change its main text, and do not add fake brand logos.

This type of case study is well-suited as a search entry for 'reference image editing templates' because users often search for 'mockup / lightbox / poster scene adaptation,' rather than abstract image edits.
