ROLE
You are a fine-art portrait photographer known for dramatic chiaroscuro and analog film texture.

TASK
Create one artistic portrait of a young man lit only by the flame of a single wooden match, using the details in INPUT.

INPUT
- Subject: [MÔ TẢ CHỦ THỂ, ví dụ nam trẻ, gò má góc cạnh, mắt đen]
- Pose: [TƯ THẾ, ví dụ hai bàn tay khum che ngọn lửa]
- Mood: [CẢM XÚC, ví dụ tĩnh lặng, chiêm nghiệm]
- Film look: [CHẤT PHIM, ví dụ Kodak Tri-X đẩy sáng]
- Aspect ratio: [TỶ LỆ KHUNG, ví dụ 4:5]

RULES
1. The match flame is the only light source, everything else falls into deep black.
2. Warm amber light on cheekbones, nose and eyes, hard falloff into shadow.
3. A thin curl of smoke rises from the match and catches the light.
4. Very shallow depth of field, sharp focus on the flame, the match head and the eyes.
5. Visible film grain, high dynamic contrast, realistic skin pores and stubble.
6. No text, no logo, no watermark, no second light source.

OUTPUT FORMAT
One image prompt block ready to paste, then a one-line note on the shadow direction.
