Quick questions on Perspective and depth explained: O-Level Art

In one-point perspective there is a single vanishing point on the horizon. It is used when you look straight at something so that one set of edges runs directly away from you, such as looking down a straight road, a corridor or railway track. All the lines running away from the viewer converge on that single point, while lines facing the viewer (the fronts of buildings, cross-streets) stay horizontal, and verticals stay vertical. Objects along the receding lines get smaller and closer together as they approach the vanishing point.

In two-point perspective there are two vanishing points on the horizon, used when you view an object from an angle so you can see two of its sides, such as the corner of a building. Each set of receding edges converges on its own vanishing point, while verticals stay vertical. Two-point perspective looks more natural and dynamic than one-point for objects seen at an angle, and is the common choice for drawing buildings and boxes in a believable way.

Linear perspective is only one tool, and several other cues create depth, often more simply. Overlap, where one object partly covers another, is the strongest and simplest: the covered object reads as further back. Relative size means smaller objects appear more distant. Position (placement) means objects higher in the picture, nearer the horizon, tend to read as further away.

Forgetting that things shrink and crowd together with distance flattens the space; diminish size and spacing toward the vanishing point.

Keeping far objects as sharp and high-contrast as near ones kills the depth; soften and cool the distance.
