Quiet Luxury Studio Duo

Using the two uploaded reference photos, create an ultra-realistic 4K UHD (2160×3840) vertical 9:16 high-end studio fashion portrait of the same man and the same woman. STRICT IDENTITY LOCK: keep both faces exactly as in the references, with the same hairstyle, skin tone and proportions. Do not regenerate the faces. Pose: three-quarter body shot, the man sits on a simple wooden stool while the woman stands slightly behind him with one hand resting gently on his shoulder, both looking directly into the lens with calm, confident expressions. 85mm lens, shallow depth of field. Outfit: the man wears a camel cashmere-look knit polo with cream tailored trousers and suede loafers; the woman wears a long-sleeve high-neck chocolate-brown thick knit dress with a loose, non-clingy silhouette, and a soft beige shawl over her shoulders, fully opaque and modest. Earthy monochrome palette. Scene: a clean studio with a seamless warm-grey backdrop, a large softbox from the left, soft shadow falloff, no props. Quality: ultra-sharp eyes and faces, natural skin texture, visible knit texture, professional medium-format look, soft cinematic grading, balanced HDR, noise reduction, premium 4K clarity. No face changes, no extra fingers, no distorted bodies, no artificial skin smoothing, no unwanted objects. 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.
