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 into an authentic Edo period samurai warrior. Maintain recognizable facial identity and natural expression.

TRANSFORMATION DESCRIPTION: Convert the subject into a noble samurai from the Edo period (1603-1868). Dress them in traditional samurai armor (yoroi) including:
- Kabuto (helmet) with crested ornament (maedate)
- Menpo (facial armor) if appropriate, or keep face visible
- Sode (shoulder guards)
- Do (chest armor) with lacquered plates
- Traditional hakama trousers
- Kimono underlayer in deep indigo or dark rust colors
- Katana sword at the waist
- Authentic samurai topknot hairstyle (chonmage) or period-appropriate long hair tied back
The transformation should look like a historically accurate portrait, not a cartoon or fantasy character. The subject should appear as a dignified, battle-ready warrior with appropriate stoic or noble expression.

STYLE AND AESTHETIC PARAMETERS:
- Art Style: Photorealistic historical portrait, cinematic quality, period-accurate
- Lighting: Dramatic studio lighting with strong rim light, reminiscent of ukiyo-e woodblock prints but photorealistic. Soft key light on face, deep shadows for mood
- Color Palette: Earth tones - deep indigos, charcoal grays, rust browns, muted gold accents. Lacquered armor should have subtle iridescent sheen. Skin tones natural and warm
- Texture: Highly detailed textures - lacquered armor plates, woven silk kimono, metal rivets, leather straps, natural skin texture with pores and fine details
- Background: Traditional Japanese setting - either a misty bamboo forest, wooden dojo interior with shoji screens, or a textured washi paper background with subtle Japanese calligraphy. Keep background slightly blurred to emphasize subject
- Composition: Classic portrait framing, subject centered, shoulders visible, looking directly at camera or slightly to the side with intense gaze

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed, ultra-sharp
- Sharp focus on face and eyes - maintain perfect facial recognition
- Professional quality, studio-grade portrait photography
- Aspect ratio: 16:9 (cinematic) or 4:3 (classic portrait)
- HDR quality with balanced highlights and shadows
- Natural skin texture preserved with pores, fine lines, and imperfections
- Armor details rendered with metallic sheen and realistic wear

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted features, unrealistic proportions, blurry face, loss of likeness, cartoonish style, anime aesthetic, fantasy elements, modern clothing, western armor, bright neon colors, oversaturated colors, deformed hands, extra fingers, asymmetrical armor, plastic-looking materials, flat lighting, low resolution, pixelation, unnatural skin smoothing

ADDITIONAL NOTES:
For best results, ensure the original photo has clear facial features with good lighting. If the uploaded photo has facial hair, it will be preserved and integrated naturally with the samurai styling. The armor should fit proportionally to the person's body type from the reference photo. If the original photo shows a specific facial expression (smiling, serious, etc.), maintain that expression while adding the samurai intensity to the eyes.
