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 the image into a space station environment.

TRANSFORMATION DESCRIPTION: Transform the person into a professional space station crew member wearing a modern, realistic astronaut uniform. Place them inside a high-tech space station corridor or observation deck with large windows showing Earth or space. The astronaut suit should be functional and authentic - white or silver with detailed patches, mission insignia, and equipment. Include subtle details like a helmet nearby or a communication device. The overall atmosphere should be realistic and professional, like a NASA or international space agency mission photo.

STYLE AND AESTHETIC PARAMETERS:
- Photorealistic, cinematic quality with professional photography standards
- Lighting: Mixed ambient space station lighting (cool LED panels, soft interior lights) combined with natural light from space windows
- Color palette: Cool blues, sterile whites, metallic silvers, with warm skin tones preserved
- Atmosphere: Professional, authentic sci-fi realism - think "The Martian" or "Interstellar" documentary style
- Background: Detailed space station interior with control panels, monitors, scientific equipment, or large observation windows
- Astronaut suit: Highly detailed with visible textures, patches, zippers, and realistic material (cloth-like, not plastic)
- Posture: Natural standing position, slightly formal for mission documentation

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face and facial features
- Professional quality, cinematic lighting
- Aspect ratio: 16:9 or 3:4 (portrait orientation)
- Ultra-detailed textures on suit fabric and space station surfaces
- Natural skin texture and pores preserved

NEGATIVE PROMPT GUIDANCE: Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, cartoonish or comic book style, low quality, pixelation, unnatural suit attachment, plastic-looking materials, poor lighting, amateur photography look

USER CUSTOMIZATION: {additional_context}

ADDITIONAL TIPS:
- For better results, ensure the original photo has clear facial lighting
- You can specify in additional_context: helmet on/off, specific suit color, background view (Earth/space/both), mission patches, or specific space station style (NASA-style, futuristic, minimalist)
- Mention if you want a specific expression (serious, smiling, focused)
