Vanishing Point

Parallel lines meet at a point that is not really there, and the audience reads that point as distance. It is the cheapest way to tell a flat picture that it has depth.

The point also becomes a place in the frame. Anything sitting at it looks far away and small, and anything between the camera and it looks like it has ground to cover.

The point sits on the horizon, at the eye level of the camera. Raise the camera and the point rises with it, which is why a high angle pushes the vanishing point up the frame and shows more ground.

It does not have to be centred. A road running off to the right puts the point on the right, and the frame stays a vanishing point composition.

Put the subject near the point or far from it. Right at the point the subject reads as the destination. Close to the lens they read as leaving. Halfway along there is no relationship to read.

Use it for journeys, for scale, and for any shot that has to say there is a long way to go.

Leave it out of a tight interior with nothing running away from the lens. There is no depth to build, and asking for it returns a flat frame with a fake gradient.

One point perspective is the strict, centred, square-on version, and it needs the whole space to line up. A vanishing point can sit off to one side with only one set of lines running to it.

Layered depth builds distance out of separate planes at different distances. A vanishing point builds it out of converging lines. The two work together and neither replaces the other.

The model returns a flat scene with a blurred far background, which is atmosphere rather than perspective. Name the parallel lines that converge: the road edges, the rail tracks, the line of poles.

The second failure is a subject stranded in the middle distance with no relationship to the point. State where the subject sits relative to it.
