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 overall appearance into a 19th-century nobleman.

TRANSFORMATION DESCRIPTION:
Transform the subject into a dignified nobleman from the 19th century (circa 1850s-1890s). Apply authentic period clothing including a tailored frock coat, waistcoat, cravat or high collar shirt, and formal trousers. Style the hair in a historical manner appropriate for the era - neatly combed side-parting or swept back style. The overall appearance should reflect aristocratic refinement and sophistication of the Victorian or Romantic era.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic historical portrait photography with cinematic quality
- Lighting conditions: Soft, directional studio lighting or natural window light typical of 19th-century portraiture, with gentle shadows that sculpt the face elegantly
- Color palette: Warm sepia tones, rich browns, deep burgundies, forest greens, and cream whites - authentic to historical photography and 19th-century fashion
- Texture details: Velvet and wool fabric textures visible, leather buttons, polished wood or leather chair in background
- Background treatment: Elegant interior setting with vintage furniture, damask wallpaper, or a subtle blurred background with hints of a study or drawing room
- Mood: Distinguished, contemplative, aristocratic, refined

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face with natural skin texture preserved
- Professional quality portrait photography
- Aspect ratio: 4:5 vertical portrait orientation
- Depth of field: Shallow focus on subject with background softly blurred
- Detail level: Individual fabric threads visible, realistic hair texture, natural skin pores

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, modern clothing elements, anachronistic accessories, unnatural skin smoothing, plastic-looking textures, exaggerated facial features, mismatched lighting, low resolution artifacts, digital noise, cartoonish style

ADDITIONAL NOTES:
The transformation should maintain the subject's natural expression while adapting it to the formal, dignified posture typical of 19th-century portraiture. Facial hair (if present in original photo) should be styled appropriately for the era. The final image should look like an authentic historical photograph or oil painting from the period, not a costume party photo.
