风格化：音乐视频电影感​

为人像照片添加暖色调逆光晕、浅景深，保留人物面部特征和姿势 100% 不变。

Transform the source image by applying a dramatic, warm cinematic aesthetic typical of high-end music videos. Crucially, the lighting must feature a strong, warm backlight (rim light) originating from behind the subject, creating a glowing golden halo on their hair and shoulders that separates them from the background, while also ensuring ample, soft frontal light on the subject's face so that facial features are clearly and evenly illuminated. The overall atmosphere should be emotional and moody with a shallow depth of field (blurred background), dominated by rich amber, gold, and deep shadow tones, precisely maintaining the original subject's facial features, pose, outfits, background, and gender 100% accurate. Perform a realistic upscale, bringing the subject into extremely sharp focus with enhanced skin texture and detail, styled as bright daytime photography with natural outdoor ambient light retained in the scene and sufficient key light on the face for a well-exposed portrait.
