The archer
shoots an arrow
with enormous energy. 

The arrow
flying straight ahead and parallel
with the earth's surface
after some time
shoots the archer right in his back.

The photograph
illustrates
quite similar logic.

The photographer
is holding his camera close to his eye.
He directs the optical axis 
of the camera
straight ahead and parallel
with the earth's surface
and yet
he is taking a photo of himself.
