Nighttime Yacht Portrait

A vertical 9:16 realistic photograph of a fictional adult woman, approximately twenty-five years old, standing on the wooden deck of a luxury yacht at night. She has long, dark, slightly wavy hair and natural facial features with a calm expression. Her outfit consists of a fitted black turtleneck maxi dress layered under an unbuttoned white oversized shirt with sleeves rolled up to her elbows; she wears a thin silver bracelet on her left wrist. The lighting is characterized by a direct flash that illuminates the subject and the immediate one-meter radius around her, while the background falls into deep shadow. The overall color palette is dominated by navy blue and obsidian tones, with fine noise visible in the dark areas. Behind her, the stainless steel railing of the yacht is visible, along with the white superstructure of the boat to the right. In the distance, the dark sea reflects scattered yellow lights from a harbor or coastline.
