A romantic cinematic beach portrait of a couple in white linen outfits

A romantic cinematic beach portrait of a couple in white linen outfits, barefoot at the shoreline with ocean foam splashing around their feet; they lean back together holding hands in a playful, suspended pose—her long dark hair flowing, his head tilted back, both wearing sunglasses and relaxed expressions, a brown leather belt and minimal accessories adding organic texture. Overcast moody sky, cool blue-gray color palette with slightly warm skin tones, soft natural light, shallow depth of field to separate subjects from a gently blurred horizon, visible wet sand and foamy waves for dynamic foreground texture. Compose from a low angle, slightly off-center to the right, include negative space of sky on the left and a leading shoreline line receding into the distance. Camera settings suggestion: 35–50mm, f/2.8–f/4, 1/400–1/800s to freeze motion, ISO 100–400. Post-processing: cool shadows, teal-blue split toning, warm highlights on skin, moderate clarity, gentle contrast, slight vignette, crisp sharpening on faces and foam, subtle film grain for organic feel, maintain natural skin tones and emphasize motion and joy. 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.
