A photorealistic image of a young professional white woman holding a smartphone

A photorealistic image of a young professional white woman holding a smartphone to her ear as if receiving a call. She is smiling warmly and looks engaged in conversation. The woman should be wearing business casual attire. She is standing in an office or home office setting with soft, natural lighting. The focus should be on her face and the phone, with the background slightly blurred but the image should show her waist up. The image should have high resolution and look like a stock photo or professional photography, not an illustration or cartoon.
