Hyperrealistic premium fitness-editorial portrait of a single subject standing beside a row of treadmills inside a modern commercial gym with mirrors, cardio machines, free weights, dark strength-training equipment, large windows, and linear overhead lighting, framed head-to-upper-thigh in the original 4:5 portrait composition with the subject centered slightly toward frame-right. Preserve the exact facial identity and physical appearance of the person in the uploaded reference image with absolute fidelity—keep the face, all identifying features, skin tone, eye appearance, hair texture, body proportions, and physique exactly unchanged; do not idealize, beautify, reshape, narrow, enlarge, blend, average, reinterpret, or alter the subject in any way. Keep the original near-frontal stance with slight three-quarter rotation, mild head tilt, frame-left arm extending toward or resting near the treadmill handle, frame-right arm relaxed beside the thigh, long very dark brown hair with natural glossy strands and broad loose waves, the exact matching light desaturated-blue athletic crop top and high-waisted leggings with their original cut, waistband height, seams, fabric weight, and fit, plus the fine pendant necklace, small earring, and white shaker cup positioned subtly on the treadmill at frame-left. Shape the light with a large soft 5400K window-style key from approximately 10 o’clock and 35° off camera, slightly above eye level, neutral camera-right fill at 30–35% of key intensity, and a restrained rear-right edge light around 2–3 o’clock at 5600–5800K to lift only the outer hair curves and silhouette while keeping the interior hair deep and dimensional; raise the face about 0.15–0.25 stop relative to the torso and background, reduce forehead, nose, shoulder, and window-side hotspots by roughly 0.2–0.3 stop, preserve the true light-blue color and microtexture of the athletic fabric without washing it toward white, and lift the deepest hair and gym shadows only enough to retain detail without turning blacks gray. Lower the distant gym exposure by about 0.4 stop, compress the bright frame-left windows by roughly 0.4–0.6 stop to retain exterior detail, reduce distracting mirror reflections and repeated bright streaks behind the head, soften local clarity on distant machines and weights while keeping the gym unmistakable, and keep the wall text “DISCIPLINE / FOCUS / STRENGTH” readable but clearly secondary to the face. Use a clean premium fitness-campaign grade with warm-neutral skin highlights, neutral shadows free from green contamination, controlled light-blue clothing, cool charcoal equipment, rich blacks, natural glossy hair, restrained 5/10 skin retouching with visible pores and micro-relief, a 50–55 mm full-frame lens feel at approximately f/2.2–f/2.8, both eyes critically sharp with natural catchlights, selective optical depth rather than artificial portrait blur, local sharpening only on eyes, lashes, lips, front hair strands, necklace, and fabric seams, restrained HDR, fine grain 1–2/10, extremely subtle vignette, no fog, smoke, particles, flare, or artificial cinematic effects, ultra-detailed, 8K.
