Transform the uploaded image into an ultra-realistic Blue Hour Rooftop Portrait Photography scene while preserving the subject's exact facial identity, facial structure, hairstyle, skin texture, body proportions, clothing, accessories, pose, expression, and all recognizable natural features.

Place the subject on an elegant high-rise rooftop during the brief blue-hour period immediately after sunset. Create a believable panoramic urban background with illuminated skyscraper windows, distant traffic lights, subtle architectural silhouettes, rooftop details, and thousands of softly glowing city lights stretching toward the horizon.

The sky should display authentic blue-hour gradients transitioning naturally from deep cobalt and indigo overhead to subtle residual warm tones near the horizon. Keep the atmosphere clean and realistic with slight natural atmospheric haze separating distant buildings.

Photograph the portrait with the visual character of a Fujifilm GFX100 II medium-format camera paired with a fast professional portrait lens around the 80–85mm equivalent range. Use a wide aperture for precise focus on the subject, smooth optical falloff, elegant compression, extremely detailed facial rendering, and large circular city-light bokeh in the background.

Balance the remaining ambient twilight with a large diffused off-camera softbox positioned naturally toward the subject. Add a very subtle rim light from the city environment to separate the subject from the skyline without creating an artificial studio appearance.

Expose the image carefully so that both the subject and illuminated city remain detailed. Preserve realistic highlight information in windows and signs while maintaining natural shadow detail, accurate skin tones, believable fabric textures, and true photographic dynamic range.

Apply sophisticated editorial color grading based on cool blue-hour tones, neutral natural skin, restrained warm city lights, refined contrast, subtle filmic highlight roll-off, and realistic blacks. The result should feel like a premium professional rooftop photo session rather than a digitally generated scene.

Include realistic optical characteristics such as gentle background compression, natural lens bokeh, subtle atmospheric depth, authentic light falloff, fine micro-contrast, and restrained photographic grain.

Do not alter the person's identity. Avoid CGI appearance, illustration, anime, excessive HDR, artificial skin smoothing, fake facial reconstruction, exaggerated neon colors, impossible architecture, unrealistic lens flare, oversaturation, excessive sharpening, duplicated buildings, distorted hands, or artificial-looking bokeh.

Final result: an exceptionally realistic high-end Blue Hour Rooftop Portrait with authentic professional photography aesthetics, sophisticated city atmosphere, natural lighting, premium editorial composition, and extremely detailed 8K photographic quality.
