Studio Portrait with Cinematic Lighting and Contrast (#nb_26)

{
    "prompt": "Transform the image into a top-tier, studio-style, close-up face portrait. She is wearing a fitted black turtleneck knit sweater, with a delicate fabric texture, clear knit patterns, and natural folds that show rich tonal variation in the shadows under the light, rather than being a pure black block. The overall style is minimalist and high-end/sophisticated. She is slightly turned to the side, with her hands naturally crossed over her chest, and her gaze is resolute and focused. The background is a dark gradient with contrasting cold blue and warm golden light halos to highlight the subject. The image utilizes a Rim Light (Back Light) to outline the hair and the edges of the shoulders and neck, while a soft Key Light is added to the front to illuminate the face, making the skin tone translucent and natural. The overall aesthetic is a cinematic color portrait, featuring a warm/cool color contrast, delicate Film Grain, and a deep, elegant atmosphere. The composition is non-centered, with the subject positioned to one side of the frame, leaving negative space on the other side to create a sense of breathing room.",
