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 image into a professional business portrait. The person's identity must remain 100% recognizable and authentic.

TRANSFORMATION DESCRIPTION:
Transform the uploaded selfie or casual photo into a professional headshot suitable for Calendly, Linktree, LinkedIn, and business profiles. The subject should be positioned in a medium close-up or bust shot, framed from the mid-chest up, with a confident and approachable expression. The pose should be natural, facing slightly towards the camera or looking directly into the lens. The background should be clean, either a solid neutral color (soft grey, white, or muted blue) or a very subtle, out-of-focus gradient that does not distract from the face. The lighting should be soft and flattering, typical of professional studio photography.

STYLE AND AESTHETIC PARAMETERS:
- Art Style: Photorealistic, professional corporate photography. Clean, sharp, and modern aesthetic.
- Lighting Conditions: Soft studio lighting with a key light creating gentle shadows to define facial structure. Use a softbox effect to eliminate harsh lines and create a flattering glow on the skin. Avoid direct, flat flash.
- Color Palette: Natural skin tones with high fidelity. The background should be neutral (soft grey, cream, or light blue) to maintain focus on the subject. Colors should look professional and not overly saturated.
- Background Treatment: Solid color or very shallow depth of field (bokeh) to keep the background completely non-distracting. No clutter, no busy environments, no harsh patterns. The focus must be entirely on the person.
- Expression and Vibe: Professional, confident, friendly, and approachable. A slight natural smile is ideal for business contexts.

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed, professional quality
- Sharp focus on face and eyes; eyes should be crisp and clear
- Natural skin texture preserved, pores visible but skin looks healthy
- Professional portrait photography quality, suitable for digital and print business cards
- Aspect Ratio: 1:1 (square) or 4:5 (vertical portrait) - suitable for profile pictures
- No artifacts, no noise, clean edges

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, harsh shadows, overexposed skin, underexposed areas, cluttered background, busy patterns, distracting elements, unnatural skin smoothing, cartoonish effects, low resolution, pixelation, bad anatomy, extra limbs, deformed eyes.
