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 characteristics while transforming them into a knight. Ensure the facial likeness remains 100% accurate and recognizable despite the armor and helmet overlay.

TRANSFORMATION DESCRIPTION:
Transform the person into a medieval knight wearing full plate armor. The armor should be ornate and historically accurate, featuring engraved metal plates, chainmail details, and a polished steel finish. Include a knight's helmet that partially or fully covers the head, but ensure the face underneath is still the user's original face. Add a flowing cape in a rich color (red, blue, or dark velvet) draped over the shoulders. The pose should be heroic and commanding.

STYLE AND AESTHETIC PARAMETERS:
- Art Style: Photorealistic, cinematic, and epic. The image should look like a high-budget fantasy movie still or a professional concept art portrait.
- Lighting: Dramatic, high-contrast lighting. Use a rim light effect to highlight the edges of the armor and the silhouette. Soft, warm light on the face to ensure facial features are clearly visible and well-lit.
- Color Palette: Metallic tones (silver, gold, steel) contrasted with deep, rich colors of the cape and background. The overall mood is heroic, noble, and slightly dark.
- Background: A medieval castle interior, a misty battlefield, or a grand hall with stone pillars. The background should be slightly blurred (bokeh) to keep focus on the person and armor.

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed, ultra-realistic textures on metal and fabric.
- Sharp focus on face and armor details.
- Professional quality, 8k render, ray tracing, studio photography lighting.
- Aspect ratio: 3:4 or 9:16 (portrait orientation).

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic armor proportions, blurry face, loss of likeness, cartoonish style, low resolution, deformed hands, extra limbs, text, watermark, signature. Do not make the armor look cheap or plastic.

ADDITIONAL TIPS FOR BEST RESULTS:
1. Start with a clear, front-facing portrait photo for the most accurate transformation.
2. If the AI covers the face too much with the helmet, add "face visible through helmet" or "open-faced helmet" to your customization section.
3. You can specify armor colors in the {additional_context} section (e.g., "silver armor with gold trim" or "black armor with red cape").
