A woman in a white coat is posing for a picture

Generate a hyper-realistic, high-resolution (4K or higher) portrait of a human. The subject should be a female in her mid-20s, with medium-length straight blonde hair, blue eyes, and a fair skin tone. She should be dressed in a black turtleneck sweater. Position her in a dimly lit setting with a dark, blurred background to focus solely on the subject. The lighting should be soft but frontal, illuminating her face evenly. Her expression should be intense and enigmatic, with a focused gaze directly into the camera. Her mouth should be closed, portraying a subtle, serious expression. The style should be photorealistic, capturing the subtle nuances of her face and attire. The image should look as if it was taken by a high-end DSLR camera with a prime lens, and it should closely resemble the style and atmosphere of the example provided.
