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 placing them in a commercial product photography context. Keep their natural expression, posture, and authentic appearance intact.

TRANSFORMATION DESCRIPTION: Transform the photo into a professional product showcase image where the person is naturally interacting with or presenting a product. The person should appear as a brand ambassador or satisfied customer, holding the product confidently or demonstrating its use. The product (which the user will describe in additional context) should be clearly visible, well-lit, and positioned naturally in the frame. Create a genuine, lifestyle-commercial aesthetic that works perfectly for Instagram posts, stories, and product listings.

- Natural, approachable model expression that builds trust with potential customers
- Sharp focus on both the face and the product with depth of field for professional look
- Color grading that enhances product visibility while maintaining natural skin tones

NEGATIVE PROMPT GUIDANCE: Avoid: distorted facial features, unrealistic product placement, blurry product details, loss of facial likeness, poor lighting, unnatural shadows, cluttered background, low resolution, amateur-looking composition, overexposed highlights, color mismatches, unnatural hand positions, product deformation, unrealistic reflections
