The horizon line is always at eye-level. For example: if you are 6'4" tall, your horizon line (eye-level) will probably be 6 feet off the ground (assuming a measurement of 4" from the top of your head down to your eyes). The true horizon line, is where the lines drawn from the top and bottom of an object or other objects, meet and this horizon line is the point where the land and sky meet, and is always on a level with the eye. (Figure – 4) The level line through the middle is the horizon and this horizon line and the vanishing point are always on a level with the eye of the person who looks at the view (The Viewer) Figure. The central line of this is the horizontal line, and you see that all the lines run to the dot at the man’s head. This dot is the vanishing point, and if the houses were built right on to this point, it would be a pretty long street, and if you should look down it, the house at this point would be out of sight.
