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 adapting the image for professional advertising use. Maintain full facial likeness and natural expression.

TRANSFORMATION DESCRIPTION:
Transform the photo into a professional promotional portrait for a masterclass or workshop. Place the person in a confident, approachable, expert role-ideal for advertising educational or creative services. The subject should appear engaged, perhaps looking directly at the camera with a warm, authoritative smile, or gesturing naturally as if explaining a concept. The overall mood should be inspiring, trustworthy, and professional.

Optional scene integration (choose one or describe in customization):
- Studio setting: Clean, modern studio background with subtle depth of field. Soft gradient or neutral color that doesn't distract.
- Workshop environment: Warm, inviting workshop space-think creative studio, classroom, or conference room with soft background blur.
- Abstract professional background: Minimalist, elegant background with soft bokeh lights or subtle geometric patterns in brand-friendly colors (e.g., deep blue, warm amber, soft gray).

Props and styling (optional):
- Light professional attire: blazer, smart casual shirt, or creative professional wear.
- Subtle gesture: holding a tablet, book, or open hand gesture.
- Accessories: glasses, subtle jewelry, or a lanyard/name badge for event authenticity.

LIGHTING AND AESTHETIC PARAMETERS:
- Style: Photorealistic, high-quality portrait photography. Clean, crisp, modern look.
- Lighting: Soft studio lighting or warm natural window light. Gentle key light on face, soft fill to reduce harsh shadows. Avoid overexposure or deep shadows.
- Color palette: Professional, warm yet muted tones. Slightly desaturated for elegance, with a subtle warmth to skin tones. Background colors should complement the subject's clothing and skin tone.
- Background treatment: Soft bokeh or blurred background to keep focus on the face. If workshop environment, keep it subtle and non-distracting.
- Depth of field: Shallow to medium, keeping eyes and face razor-sharp.

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed, professional quality
- Sharp focus on face, especially eyes and expression
- Natural skin texture preserved, no plastic or overly airbrushed look
- Professional portrait photography quality
- Aspect ratio: 16:9 for web banners, 4:5 for social media posts, or 1:1 for profile pictures

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, unnatural skin smoothing, harsh lighting, cluttered background, distracting elements, overly saturated colors, artificial-looking smile, low resolution, pixelation, watermark, text overlays, logo, or branding.
