IDENTITY PRESERVATION INSTRUCTION:
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while transforming it into a professional document photo. The person's identity must remain completely recognizable and authentic.

TRANSFORMATION DESCRIPTION:
Transform the uploaded photo into a professional document photo suitable for official use (passport, visa, ID card, driver's license, or resume). Create a standardized portrait with a neutral facial expression, looking directly at the camera with both eyes open and mouth closed in a natural, relaxed state. The subject should be positioned centered in the frame with shoulders visible, facing forward with a straight head posture. The transformation should maintain a professional, clean appearance appropriate for government and institutional requirements.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic and professional document photography with natural skin texture
- Lighting conditions: Even, soft studio lighting with minimal shadows on the face; professional key light at 45-degree angle, fill light to reduce shadows; no harsh lighting or dramatic effects
- Color palette: Natural skin tones with accurate color representation; professional and neutral color grading
- Background treatment: Solid, uniform background in standard document colors - pure white (#FFFFFF) or light blue (#E6F2FF) depending on regional requirements; completely smooth and even with zero texture or gradient; background should be seamlessly integrated with subject
- Facial expression: Neutral, professional, and natural - mouth closed, eyes open and looking directly at camera, no smile or frown, relaxed facial muscles
- Pose: Centered composition, head straight, shoulders visible, facing camera directly

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face with clear definition of facial features
- Professional quality document photography standards
- Aspect ratio: 1:1 (square) or 3:4 (portrait) depending on document requirements
- Proper head size relative to frame (typically 70-80% of frame height)
- Natural skin texture preserved with no artificial smoothing
- Clean edges around hair and shoulders
- Consistent exposure across the entire frame

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, unnatural skin smoothing, harsh shadows, uneven lighting, artificial expressions, unnatural head tilt, off-center composition, background texture or patterns, color casts on skin, overexposed or underexposed areas, visible artifacts or noise, unnatural eye reflections, unnatural skin tone changes, facial warping, asymmetrical features, unnatural background blending
