- **Framing & Shot Type**: Extreme close-up macro (Dutch tilt diagonal dynamic angle)
- **Optics & Focal Intent**: 35mm documentary environmental lens at f/1.4 ultra-shallow depth of field with creamy background separation
- **Lighting Atmosphere**: Vibrant cinematic dual-tone lighting (warm key + cool ambient rim)
- **Color Grading**: Monochrome high-contrast black and white with rich tonal gradients
- **Model Constraints**: Preserves natural skin texture; avoids oversaturated smoothing.

💡 **How To Customize**: Replace `{SUBJECT}` with your exact character or scene, or switch the Aspect Ratio to `9:16` for mobile reels and wallpaper formats.
