暗调硬光人像特写 AI 绘画提示词，忧郁氛围感女性肖像

Photography, close-up portrait, low-key hard light, dark warm brown skin tones, shallow depth of field. Slightly right of center is a close-up of a young woman's face, head tilted slightly, chin lowered, gaze directed downward toward the lens, quiet expression with a faint sense of distance and weariness. She has long, dark brown almost black straight hair, fine and messy, with many loose strands crossing her forehead, eyes, nose bridge and lips, casting thin shadows on her face; hair falls down both sides framing her cheeks and neck, denser on the left and almost covering the left edge of the frame. Near the camera on the left is a raised arm or hand, blurred and darkened, forming a foreground occlusion. Hard light comes from the front left, illuminating the forehead, nose bridge, left cheek and lower lip, while the right cheek and neck fall quickly into deep shadow, creating a clear light-dark division along the side of the nose; the lips have a soft moist highlight and there are small catchlights in the eyes. Skin is warm light brown with natural flush, retaining real pores and fine texture, not over-retouched. Main colors are deep brown-black and warm skin tones, with dark rose red on the lips as an accent, overall low saturation, low brightness, high contrast ratio. The background is pure black with no detail, merging with the hair, only the face emerging from the darkness; spatial layers are formed by the blurred arm in the foreground, the sharp face in the midground and the pure black background. Vertical close-up framing, natural perspective, the face occupies most of the frame, shallow depth of field slightly blurs hair tips and shoulder edges. The mood is built from the dark background, hard-light shadows and messy hair: quiet, intimate, slightly melancholic. Realistic photographic texture, clear detail, slight film grain, shadow detail retained, no text.
