Chân Dung Studio Tương Phản Sáng Tối Với Vệt Sáng

{
  "prompt": "A dynamic portrait of a [man] against a deep [red] dark gradient studio background, featuring high-contrast chiaroscuro lighting. A horizontal band of light illuminates only the subject's eyes and nose bridge, sharp along the lower edge and softly diffusing toward the brow, casting the rest of the face and body into deep shadows and near-silhouette. The [man] faces forward while gazing intensely off-camera. Cinematic studio photography captured on a RED V-RAPTOR cinema camera with rich skin textures and shallow depth of field sharply focused on the illuminated eyes. No text or logos.",
