地铁通道横置广告屏样机绿幕画面图片

Embedded advertising billboards inside the subway station passage, with a screen displaying pure green without any shadows, making it easy to remove and replace content in post-production. The modern and minimalist white tiled wall adds atmosphere, with blurred pedestrian background. The main subject is centered and occupies three-quarters of the frame, ensuring it is fully visible within the frame. 16:9 widescreen, realistic subway space photography style.
