A bright, romantic portrait of a young couple standing close together

A bright, romantic portrait of a young couple standing close together against a vibrant blue sky filled with fluffy white clouds and a large heart-shaped cloud above them; they wear matching rich red cable-knit sweaters and red pants, the woman with long dark hair tied with a satin red ribbon, the man with short dark hair and light beard, both smiling warmly, their arms raised to form a heart shape framing the heart cloud. Soft natural sunlight, high saturation and contrast, crisp detail on knit texture and facial features, shallow depth of field with gentle bokeh, centered vertical composition from mid-thigh up, cinematic color grading with warm highlights, subtle film grain and soft vignette for a cozy, dreamy romantic 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.
