Ultra-realistic DSLR Outdoor Portrait

Ultra-realistic DSLR outdoor portrait. Use the uploaded image as the only facial reference with absolute identity lock. Face integrity: Do not alter skull structure, facial proportions, jaw width, cheek volume, nose shape, lip form, eyebrow thickness, eye spacing, beard density, hairline, curl pattern, or natural asymmetry. Preserve real skin texture, pores, mild under-eye shadows, natural tonal variation. No smoothing, no beauty retouch, no skin glow, no sharpening, no symmetry correction, no age shift. Camera & optics: Full-frame DSLR look, 50mm prime lens, f/2.8, ISO 100, 1/500 shutter. True optical depth of field with realistic falloff. No artificial blur mask. Natural lens compression. Subtle real lens characteristics only (minimal vignette, no fake cinematic effects). Lighting: Authentic midday natural sunlight. Sun positioned slightly front-left at ~45°. Clean directional light with soft but defined shadows under chin and neck. No HDR stacking. No dramatic contrast boost. No orange/teal grading. Neutral white balance (~5200–5600K). Balanced highlights without clipping. Natural skin exposure priority. Background realism: Actual outdoor balcony setting with matte black metal railing at waist level. Mid-ground filled with dense green trees in proper daylight tonality (multiple shades of green, not neon). Far background soft natural hills/mountains with atmospheric perspective haze (subtle bluish distance fade). Clear sky with gentle gradient from light blue near horizon to deeper blue upward. Background blur must be optically consistent with subject distance and lens aperture, not software smudge. Color science: True-to-life DSLR color rendering. Slightly muted greens, accurate skin tones, realistic contrast curve. No oversaturation. No hyper clarity. No AI gloss. Preserve natural dynamic range. Composition: Vertical portrait 4:5 ratio. Mid-torso framing. Natural headroom. Eye-level camera height. Relaxed posture, hands in pockets. Black crew-neck t-shirt under light grey overshirt with flap pockets. Final output must look indistinguishable from a professional real camera photograph. No AI stylization artifacts. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
