都市夜景中独行年轻人的黑白电影肖像

Google Gemini Nano Banana Pro Prompt:Create an ultra-realistic black-and-white cinematic portrait of a young man walking through a busy night-time city - use face reference exactly. He remains sharply in focus while the crowd around him blurs into dynamic motion, creating a striking sense of isolation, depth, and introspection. Soft urban lights form abstract bokeh streaks behind him, enhancing the moody atmosphere. His expression is intense and thoughtful, hair slightly tousled, wearing a dark coat layered over a loosely unbuttoned shirt. High-contrast lighting, shallow depth of field, dramatic motion blur, film-noir aesthetic, and clean poster-style framing with crisp 8K realism.
