For the particular case of a camera it is confusing because the normal way to take photographs is to hold the camera in front of you, and the lens is on the front of the camera. I'd bet that if you asked ten people to draw a front-facing camera, or to hold a camera in a front-facing position, they would point it away from themselves and not backwards towards their own face. Cameras are not like televisions or stereos - they normally have the lens at the front and the controls at the back.
