Edit this portrait to a unified professional style. Ensure a pure, solid white background with perfectly clean edges around the subject. Significantly enhance and upscale the original image to fix any blurriness or pixelation, ensuring high quality, sharp focus, and high clarity of the man's face (he has short brown hair, a light beard, and is wearing a plaid suit with a white shirt and dark red tie). The final result should be a high-resolution professional corporate headshot with studio lighting.
