Transform the uploaded photo into a premium cinematic natural-window-light portrait photographed with a professional full-frame camera and an 85mm prime lens.

Preserve the subject's exact identity, facial structure, recognizable features, hairstyle, skin tone, body proportions, and natural appearance. Do not redesign or beautify the face beyond realistic professional photography.

Place the subject beside a large studio window with soft directional daylight entering from one side of the frame. Create a smooth transition between illuminated areas and gentle natural shadows across the face, producing realistic dimensional depth.

Simulate an 85mm portrait lens at approximately f/1.8 with authentic optical compression, shallow depth of field, sharp focus on the eyes, realistic eyelashes, natural catchlights, detailed hair strands, subtle skin pores, and smooth photographic background separation.

Use a sophisticated neutral interior background with soft cream, warm beige, and muted gray tones. Keep environmental details minimal and naturally blurred so all visual attention remains on the subject.

Apply professional cinematic color grading with realistic skin tones, softly controlled highlights, rich but clean midtones, subtle shadow detail, restrained contrast, and a gentle filmic highlight roll-off.

The lighting must feel completely photographic: no artificial glow, no excessive HDR, no plastic skin, no oversharpening, no fake beauty filter, no unrealistic facial symmetry, and no obvious AI-generated texture.

Add extremely subtle natural film grain and realistic full-frame camera micro-contrast while maintaining fine facial details.

Composition: elegant editorial portrait framing, natural posture, authentic expression, eye-level camera position, professional negative space, balanced composition.

Final result: photorealistic professional portrait photography, cinematic window lighting, authentic 85mm lens rendering, premium editorial quality, realistic skin texture, natural depth of field, high dynamic range, refined color science, ultra-detailed professional photography, 8K quality.
