黑白极简沉思肖像

{
  "prompt": "Ultra-realistic black-and-white studio portrait inspired directly by the uploaded reference image. Maintain the same hairstyle, youthful appearance, and facial profile style — the subject must remain visually consistent with the reference (no identity change). A young man sits sideways on a wooden chair, legs crossed, one arm resting naturally over the chair back, the other hand gently clasped near his lap. Head turned slightly to the right with a poised, thoughtful expression. Wearing a sleek black fitted half-zip sweater, tailored black trousers, black socks, and polished lace-up dress shoes. Clean minimal studio setting with smooth background gradients, soft diffused lighting creating gentle highlights and shadows on jawline and fabric texture. High-contrast monochrome tone, crisp skin details, editorial fashion magazine aesthetic, DSLR shot, ultra-sharp 8K realism. Vertical portrait composition, elegant and minimalistic.",
  "negative_prompt": "do not change facial features or identity style, no completely different person, no cartoon or painting effect, no unrealistic smoothing, no blur, no distortion, no extra fingers or broken hands, no grainy low-quality output, avoid harsh overexposed lighting"
