วางตัวละครในงานประชุมสุดอลังการ

A wide-angle, candid documentary photograph capturing the person from {reference_image} mid-speech on a large, professionally lit stage at a major technology summit. They are holding a microphone and gesturing naturally toward the audience. Behind them, an immense, wall-sized LED screen is fully visible, displaying a crisp, **full-screen presentation slide (showing only the slide content, absolutely no PowerPoint software interface, toolbars, or window borders)**. The slide content is professionally designed based on the theme: '{speech_topic_or_outline}'. The heads and shoulders of a large audience are visible in the **very bottom foreground, low in the frame and blurred, completely ensuring an unobstructed view of the entire stage screen**. Professional stage lighting with blue and sharp spotlights on the speaker. Shot with a high-resolution camera, sharp focus on both the speaker and the screen content, realistic film grain.
