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 changing the background. Maintain all facial details, expressions, and identity markers exactly as they appear in the original photo.

TRANSFORMATION DESCRIPTION: Replace the existing background with a new scene while keeping the person perfectly intact. The subject should be seamlessly integrated into the new environment with natural lighting interaction and realistic shadows. The new background should complement the person's appearance and create a cohesive, professional-quality image.

STYLE AND AESTHETIC PARAMETERS:
- Photorealistic quality with natural lighting that matches the new environment
- Seamless background integration with realistic depth of field
- Professional portrait photography style
- Natural skin texture and detail preservation
- Harmonious color palette that complements both subject and background
- Soft to moderate background blur (bokeh) to emphasize the subject
- Realistic light wrapping and ambient color reflection on subject
- High attention to edge blending and natural transitions

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus maintained on face and upper body
- Professional quality studio or location photography standards
- Natural skin texture preserved without smoothing
- Aspect ratio: 1:1 (square) or 4:5 (portrait) - choose based on your needs
- Clean edges around hair and clothing
- Consistent lighting directionality

NEGATIVE PROMPT GUIDANCE: Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, unnatural lighting on subject, poor edge blending, mismatched color temperature, visible artifacts around hair or edges, artificial-looking background, floating subject effect, inconsistent shadows

USER CUSTOMIZATION: {additional_context}

EXAMPLE USAGE TIPS: For best results, mention specific background preferences in the customization section, such as 'beach sunset', 'modern office', 'forest path', 'city skyline', 'studio gradient', or 'travel destination'. Specify lighting style (natural daylight, golden hour, studio softbox, dramatic cinematic) and mood (professional, casual, romantic, adventurous).
