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 a 1920s jazz musician. The core identity must remain completely recognizable - maintain the natural expression, facial structure, and all distinctive marks while applying period styling.

TRANSFORMATION DESCRIPTION:
Transform the subject into an authentic 1920s jazz musician or speakeasy performer. The person should appear as if they are a talented musician from the Jazz Age, ready to perform in a smoky underground club. Apply era-appropriate clothing, accessories, and grooming while keeping the original person's face and identity intact. The transformation should look natural and believable for this specific individual.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic vintage photography with subtle film grain texture, reminiscent of 1920s-1930s portraits
- Lighting: Dramatic chiaroscuro lighting typical of speakeasy environments - warm golden key light from above/side, deep shadows, soft ambient glow from vintage lamps
- Color palette: Warm sepia tones, rich amber and mahogany hues, deep blacks, subtle gold accents, desaturated overall with period-appropriate color grading
- Period clothing: Classic 1920s jazz attire - tailored three-piece suit (pinstripe or solid wool), crisp white dress shirt with rounded collar, silk tie or bow tie, suspenders, polished leather shoes, optional fedora or newsboy cap positioned stylishly
- Accessories: Vintage musical instrument (saxophone, trumpet, or clarinet) held naturally, pocket watch chain, leather gloves, round spectacles optional
- Grooming: Period-appropriate hairstyle - slicked-back hair with side part, finger waves, or short cropped style with neat sideburns; well-groomed facial hair if applicable (thin mustache, clean shave)
- Background: Atmospheric speakeasy setting - dimly lit brick wall with vintage posters, wooden bar interior, velvet curtains, soft bokeh lights, or elegant studio backdrop with heavy drapes
- Texture details: Visible fabric texture on wool suits, leather instrument cases, brass instrument details, wood grain on instruments

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face with natural depth of field
- Professional quality portrait photography
- Aspect ratio: 1:1 or 4:3 for classic portrait format
- Natural skin texture preservation with subtle vintage film grain overlay
- Detailed fabric and material rendering
- Cinematic composition with rule of thirds

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted features, unrealistic proportions, blurry face, loss of likeness, modern clothing elements, contemporary hairstyles, digital artifacts, over-saturated colors, cartoonish rendering, plastic-looking textures, mismatched lighting, unnatural skin smoothing, exaggerated facial expressions, incorrect period details, modern accessories (smartphones, digital watches)

FINAL INSTRUCTIONS:
Ensure the transformation feels authentic to the 1920s era while maintaining complete facial recognition. The subject should look like themselves dressed for a jazz performance in the Roaring Twenties, not like a costume or mask. All visual elements should integrate naturally with the person's existing features and proportions.
