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 woman's face (she has brown hair parted in the middle, smiling, and is wearing a black and white houndstooth patterned collared shirt). The final result should be a high-resolution professional corporate headshot with studio lighting.
