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 them to appear 20-30 years older. Maintain the fundamental identity and recognizable likeness of the person in the source image.

TRANSFORMATION DESCRIPTION:
Apply realistic aging effects to create a natural appearance of the person 20-30 years in the future. Add subtle to moderate wrinkles around eyes (crow's feet), forehead, and mouth area. Include age-appropriate hair changes such as natural graying, silver streaks, or thinning hair texture. Adjust facial structure to show natural maturation - slightly softer jawline, possible subtle skin texture changes, and age-appropriate skin tone variations. Maintain the person's distinctive features while making the aging believable and gradual.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic portrait photography with natural skin texture and realistic aging effects
- Lighting conditions: Soft, flattering studio lighting or natural window light that highlights facial features without harsh shadows
- Color palette: Natural skin tones with age-appropriate warmth or coolness, realistic hair color transitions to gray/silver
- Background treatment: Keep original background or apply subtle blur to maintain focus on the face
- Facial details: Realistic skin texture with fine lines, natural pores, and age spots where appropriate
- Hair texture: Detailed individual strands showing gray/silver variations, natural thinning patterns
- Expression: Maintain the person's natural expression from the original photo

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face and eyes
- Professional quality portrait photography
- Aspect ratio: 1:1 (square) or 4:3 (standard portrait) depending on original photo
- Natural skin texture preserved with realistic aging details
- No artifacts or distortions in facial features

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, exaggerated aging effects, unnatural skin texture, mismatched lighting, cartoonish appearance, artificial wrinkles, sudden drastic changes, loss of identity, inconsistent age progression

USER CUSTOMIZATION:

Additional Notes:
- The aging should appear natural and gradual, not sudden or extreme
- Focus on realistic human aging patterns rather than caricature
- Preserve the person's unique identifying marks (moles, scars, distinctive features) unless they would naturally change with age
- The transformation should look like the same person at an older age, not a different person entirely
