IDENTITY PRESERVATION INSTRUCTION: Using the uploaded photo as the primary reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique identifying characteristics. The core identity must remain recognizable across both age representations.

TRANSFORMATION DESCRIPTION: Create a single, cohesive image showing the same person at two distinct ages in one frame. The composition should feature the person in their current or younger appearance on one side, seamlessly transitioning to their realistically aged version on the opposite side. The aged version should show natural aging signs: subtle wrinkles, age spots, hair texture changes (graying/thinning), and slightly altered facial structure, while maintaining the person's fundamental identity. The transition between ages should be artistic and visually harmonious, either through a split-screen composition, a morphing effect, or a reflective/mirror arrangement.

STYLE AND AESTHETIC PARAMETERS:
- Art Style: Photorealistic portrait quality with cinematic storytelling elements
- Lighting: Soft, flattering studio lighting that flatters both age representations; consistent light direction across both versions
- Color Palette: Warm, nostalgic tones with subtle desaturation for the older version to denote the passage of time
- Background: Keep background neutral and cohesive (soft bokeh, blurred interior, or abstract gradient) to avoid distraction from the facial transformation
- Facial Details: For the older version - realistic skin texture with fine lines, natural wrinkles around eyes and forehead, slight loss of elasticity; for younger version - smoother skin, more vibrant tone; both versions should look natural and authentic to the person
- Expression: Maintain similar or complementary expressions that tell a story across time

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus maintained on both faces
- Professional portrait quality with natural skin texture preserved
- Clean edges and seamless integration between the two age versions
- Aspect ratio: 16:9 (cinematic) or 4:3 (classic portrait) recommended

NEGATIVE PROMPT GUIDANCE: Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, unnatural skin texture, mismatched lighting between age versions, cartoonish aging effects, inconsistent eye color, artificial-looking wrinkles, cloned appearance (both versions looking identical), gender changes, ethnicity changes, exaggerated aging effects

USER CUSTOMIZATION: {additional_context}

ADDITIONAL TIPS FOR BEST RESULTS:
- Use a well-lit, clear photo with face visible and minimal obstructions
- Front-facing portraits work best for accurate age transformation
- If you have a specific age range in mind (e.g., 25 vs 65), mention it in {additional_context}
- For more dramatic effect, you can request specific aging features like glasses, different hairstyle, or facial hair in the older version
