The woman in the white coat is holding a camera in her hand.
The woman is sleeping.
If one is sleeping, they generally are not holding a camera.
The woman can not be sleeping and holding a camera.
A woman could be asleep wearing a white coat and holding a camera in her hand. If the intent of holding a camera is to take a picture, then this is the contradiction. However, since the intent is not clear, I can find no other contradictions.
