Transform the uploaded photo into an ultra-photorealistic professional studio portrait captured with the visual character of a high-resolution Sony full-frame mirrorless camera and a premium 85mm portrait prime lens, illuminated with authentic cinematic Rembrandt lighting.

Preserve the subject's exact identity and recognizable appearance. Maintain the original facial structure, face shape, eyes, nose, lips, jawline, eyebrows, hairstyle, hairline, skin tone, expression, body proportions, clothing characteristics, accessories, and all distinctive visible features.

Do not redesign, beautify, age, de-age, or replace the person's face. The finished portrait must unmistakably depict the same person from the uploaded photograph.

Place the subject inside an elegant professional portrait studio with a minimal neutral background featuring subtle charcoal-gray to warm-gray tonal transitions and extremely restrained environmental texture.

Simulate the perspective and optical rendering of a premium 85mm prime portrait lens at approximately f/1.8.

Create authentic 85mm optical compression with flattering but physically believable facial proportions, smooth background separation, realistic depth transitions, natural edge falloff, and creamy optical bokeh without artificial computational blur.

Position the camera approximately at the subject's eye level and maintain a realistic professional portrait shooting distance.

Create authentic Rembrandt portrait lighting using one large diffused key light positioned approximately 45 degrees to the side of the subject and slightly above eye level.

The key light should illuminate one side of the face while allowing the nose shadow to connect naturally with the shadowed cheek, leaving a small, recognizable triangular patch of light beneath the eye on the darker side of the face.

Keep the Rembrandt triangle subtle and photographically believable rather than exaggerated.

Add extremely gentle fill illumination from the camera side to preserve information in the shadows without destroying the characteristic Rembrandt lighting pattern.

Introduce a restrained separation light from behind the subject to create a delicate highlight along selected edges of the hair, shoulder, and clothing. Keep this light subtle and physically consistent with a professional studio setup.

Maintain realistic inverse-square light falloff across the subject and background.

Render human skin with exceptional realism. Preserve natural pores, fine facial lines, tiny variations in complexion, individual eyebrow hairs, eyelashes, beard or mustache texture when present, subtle facial hair, realistic lips, and natural skin reflectivity.

Do not use beauty-filter skin smoothing.

Eyes must remain exceptionally detailed with natural iris structure, realistic pupil size, subtle moisture along the lower eyelid, sharp eyelashes, and physically believable catchlights corresponding precisely to the studio key light.

Render individual hair strands with realistic density, direction, texture, and naturally illuminated edges.

Preserve the original clothing style and important garment details. Reproduce realistic fabric weave, stitching, buttons, folds, seams, embroidery, patterns, and natural material response to studio lighting.

Use professional Sony-style high-resolution digital rendering with exceptional autofocus precision on the nearest eye, refined micro-contrast, realistic fine detail, broad dynamic range, and clean tonal transitions.

Maintain controlled highlights on the forehead, nose, cheeks, lips, eyes, and clothing without clipping bright areas.

Keep shadow regions deep and cinematic while retaining subtle facial and fabric information.

Apply sophisticated editorial color grading with realistic skin tones, restrained saturation, slightly warm highlights, neutral midtones, gently cooler deep shadows, and smooth cinematic highlight roll-off.

Keep white clothing naturally neutral without introducing unrealistic blue, yellow, or magenta contamination.

Use shallow depth of field that appears optically generated by a real 85mm lens. The eyes and essential facial features should remain sharply resolved while the ears, shoulders, and background transition gradually into natural softness according to their distance from the focal plane.

Add extremely subtle full-frame sensor texture and microscopic photographic grain only where appropriate. The photograph must remain clean and modern rather than resembling vintage film.

Composition: premium studio head-and-shoulders or three-quarter portrait, eye-level perspective, natural confident posture, authentic expression, balanced negative space, refined editorial framing, and professional visual hierarchy.

The photograph should communicate quiet confidence, elegance, dimensionality, and timeless professional portraiture.

Avoid plastic skin, excessive skin smoothing, artificial HDR, oversharpening, glowing facial edges, excessive rim lighting, fake bokeh, incorrect catchlights, crushed shadows, blown highlights, excessive color grading, facial asymmetry corrections, altered identity, distorted hands, malformed clothing, duplicated details, or obvious AI-generated artifacts.

Lighting, shadows, reflections, depth of field, skin response, clothing illumination, and background exposure must remain physically coherent as if everything were photographed simultaneously inside a real professional studio.

Final result: ultra-photorealistic professional Sony-inspired studio portrait, authentic 85mm prime lens perspective, cinematic Rembrandt lighting, precise eye focus, natural skin micro-texture, dimensional facial lighting, smooth optical background separation, refined dynamic range, sophisticated editorial color science, premium magazine portrait quality, exceptionally realistic professional photography, high-resolution 8K detail.
