Waist-up intimate portrait of a young affectionate couple

Waist-up intimate portrait of a young affectionate couple outdoors in soft natural light, man standing behind woman with arms wrapped around her waist, both smiling gently and wearing stylish black sunglasses; man has thick dark hair, black-and-yellow hoodie and distressed blue jeans, woman has long wavy brown hair, hoop earring, vibrant mustard-yellow kurta with deep blue embellished panel and matching blue open jacket, silver wristwatch and simple rings visible. Sharp focus on faces with shallow depth of field, creamy bokeh background of neutral architecture and greenery, warm cinematic color grading, vivid saturated yellows and deep blues, balanced contrast and natural skin texture, soft catchlights in sunglasses, subtle vignette, high-resolution, photorealistic, slight film grain for richness, 2:3 vertical composition, framed centrally with headroom and rule-of-thirds balance, natural retouching only to enhance eyes, hair shine and fabric detail while preserving realism. 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.
