1. Big and Small
Sucessively reducing the size of objects and things creates the impression that they are positioned behind each other. On the other hand, children (similar to artists in the Middle Ages) draw the sizes of objects depending on importance, not distance. The top of the picture represents the back to them.
With objects of identical shape, the smaller ones appear to sit farther back.
Not only do shapes become smaller, the distance between them becomes shorter the farther back they are.
Wide lines become thinner the more distant they are. The impression of regular repetition is important for depth perception.
The imagined horizon line staggers the areas in space.
Below is in front; above is in back— no matter how big the trees are.
The street edge defines the terrain. That’s why the gradually receding street disappears behind the hills, its smooth course broken up.
The various line widths show the spatial order of the three walls.
When clear overlaps are missing, it is not always obvious whether the small shapes are farther back than the bigger ones.
Depicted here are sounds swinging in space: quiet and loud.
Condensing generates depth. The space pulls together at compressed areas because the distance between the lines is smaller there.
