Prompt Template
Close-up black and white portrait of a man and a woman standing side by side. The man has tousled hair and a rough beard, the woman has softly tousled natural hair. Both tilt their heads slightly upward as dramatic overhead light falls on them. Their eyes remain in shadow, creating a powerful, mysterious, silhouette-like mood with strong contrast. 9:16 composition, intimate dual-portrait framing.
