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 webinar banner. The face must remain 100% recognizable and anatomically correct.

TRANSFORMATION DESCRIPTION:
Transform the subject into a confident, professional speaker or host suitable for a webinar or online marathon banner. The person should be positioned dynamically, perhaps looking slightly off-camera or directly at the viewer with an engaging expression. The background should be replaced with a modern, high-tech, or clean studio environment that implies authority and expertise. The overall composition should leave space for text overlay (typical banner format).

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic, cinematic corporate photography, high-end commercial look.
- Lighting conditions: Professional studio lighting with a key light creating soft shadows on the face, rim lighting to separate subject from background, and a catchlight in the eyes to make them pop. Slight blue or purple accent lights in the background for a modern tech feel.
- Color palette: Professional and vibrant. Cool tones in the background (blues, greys) contrasting with warm skin tones. High contrast and saturation to stand out on digital screens.
- Background treatment: Replace background with a blurred, modern office setting, a sleek abstract digital background, or a professional stage with soft bokeh lights. The background should be visually interesting but not distracting from the face.

TECHNICAL QUALITY PARAMETERS:
- high resolution, 4K, detailed
- sharp focus on face
- professional quality
- 16:9 aspect ratio (standard banner format)
- Ultra-detailed skin texture and hair rendering
- No pixelation or artifacts
