Create a 16:9 photorealistic amateur smartphone photo taken from far back in the audience during a fictional next-generation smartphone launch event at a circular glass technology campus auditorium. Do not use real technology company names, logos, real executives, or copied product designs. A fictional technology CEO is standing on stage giving a keynote presentation. A huge black presentation screen behind them shows a sleek fictional smartphone render and clean launch text for a fictional product, with no real brand marks. The foreground includes the backs of audience members' heads and raised phones, making the shot feel like a candid crowd-view photo rather than an official press image. Use realistic indoor keynote lighting, glass architecture, a broad stage, slight handheld framing, natural perspective, and documentary photo realism.
