On the right image all that I have done is had her turn her face slightly back towards the camera.

右边的照片，我仅仅是让她的脸向相机的方向转回一点点。

Sit in a chair or on a stool, facing to the left or right. Then turn your head slightly to look over your shoulder at the camera. The camera should be at your eye level.

坐在椅子或凳子上，脸朝左面或者右面，然后稍微转头看着镜头，照相机镜头要和你的眼睛水平。
