Studio portrait of a loving couple in a vertical frame, woman standing behind

Studio portrait of a loving couple in a vertical frame, woman standing behind a seated man with her arms gently draped over his shoulders, both facing the camera with warm, confident smiles; black seamless background with a single soft spotlight from above creating a subtle halo and delicate rim light on hair and shoulders and smooth falloff into deep shadow. Both wear fitted black shirts, minimal jewelry, woman with long glossy dark waves and natural, refined makeup, man with short cropped hair and neat beard; camera at eye level, portrait focal length, shallow depth of field to keep faces tack-sharp and background creamy, pronounced catchlights in the eyes. High-resolution, cinematic color grading with warm natural skin tones, moderate contrast, gentle skin retouching for a natural look, crisp texture in hair and fabric, slight film grain and soft vignette for timeless, elegant, intimate mood. 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.
